Data center scalability is the ability to increase or decrease workloads cost-effectively and without disrupting business operations. Scalable data centers make organizations agile, enabling them to support business growth, meet changing customer needs, and weather downturns without compromising quality. This blog describes various methods for achieving data center scalability before providing tips and best practices to make scalability easier and more cost-effective to implement.

How to achieve data center scalability

There are four primary ways to scale data center infrastructure, each of which has advantages and disadvantages.

 

4 Data center scaling methods

Method Description Pros and Cons
1. Adding more servers Also known as scaling out or horizontal scaling, this involves adding more physical or virtual machines to the data center architecture. ✔ Can support and distribute more workloads

✔ Eliminates hardware constraints

✖ Deployment and replication take time

✖ Requires more rack space

✖ Higher upfront and operational costs

2. Virtualization Dividing physical hardware into multiple virtual machines (VMs) or virtual network functions (VNFs) to support more workloads per device. ✔ Supports faster provisioning

✔ Uses resources more efficiently

✔ Reduces scaling costs

✖ Transition can be expensive and disruptive

✖ Not supported by all hardware and software

3. Upgrading existing hardware Also known as scaling up or vertical scaling, this involves adding more processors, memory, or storage to upgrade the capabilities of existing systems. ✔ Implementation is usually quick and non-disruptive

✔ More cost-effective than horizontal scaling

✔ Requires less power and rack space

✖ Scalability limited by server hardware constraints

✖ Increases reliance on legacy systems

4. Using cloud services Moving some or all workloads to the cloud, where resources can be added or removed on-demand to meet scaling requirements. ✔ Allows on-demand or automatic scaling

✔ Better support for new and emerging technologies

✔ Reduces data center costs

✖ Migration is often extremely disruptive

✖ Auto-scaling can lead to ballooning monthly bills

✖ May not support legacy software

It’s important for companies to analyze their requirements and carefully consider the advantages and disadvantages of each method before choosing a path forward. 

Best practices for data center scalability

The following tips can help organizations ensure their data center infrastructure is flexible enough to support scaling by any of the above methods.

Run workloads on vendor-neutral platforms

Vendor lock-in, or a lack of interoperability with third-party solutions, can severely limit data center scalability. Using vendor-neutral platforms ensures that teams can add, expand, or integrate data center resources and capabilities regardless of provider. These platforms make it easier to adopt new technologies like artificial intelligence (AI) and machine learning (ML) while ensuring compatibility with legacy systems.

Use infrastructure automation and AIOps

Infrastructure automation technologies help teams provision and deploy data center resources quickly so companies can scale up or out with greater efficiency. They also ensure administrators can effectively manage and secure data center infrastructure as it grows in size and complexity. 

For example, zero-touch provisioning (ZTP) automatically configures new devices as soon as they connect to the network, allowing remote teams to deploy new data center resources without on-site visits. Automated configuration management solutions like Ansible and Chef ensure that virtualized system configurations stay consistent and up-to-date while preventing unauthorized changes. AIOps (artificial intelligence for IT operations) uses machine learning algorithms to detect threats and other problems, remediate simple issues, and provide root-cause analysis (RCA) and other post-incident forensics with greater accuracy than traditional automation. 

Isolate the control plane with Gen 3 serial consoles

Serial consoles are devices that allow administrators to remotely manage data center infrastructure without needing to log in to each piece of equipment individually. They use out-of-band (OOB) management to separate the data plane (where production workflows occur) from the control plane (where management workflows occur). OOB serial console technology – especially the third-generation (or Gen 3) – aids data center scalability in several ways:

  1. Gen 3 serial consoles are vendor-neutral and provide a single software platform for administrators to manage all data center devices, significantly reducing management complexity as infrastructure scales out.
  2. Gen 3 OOB can extend automation capabilities like ZTP to mixed-vendor and legacy devices that wouldn’t otherwise support them.
  3. OOB management moves resource-intensive infrastructure automation workflows off the data plane, improving the performance of production applications and workflows.
  4. Serial consoles move the management interfaces for data center infrastructure to an isolated control plane, which prevents malware and cybercriminals from accessing them if the production network is breached. Isolated management infrastructure (IMI) is a security best practice for data center architectures of any size.

How Nodegrid simplifies data center scalability

Nodegrid is a Gen 3 out-of-band management solution that streamlines vertical and horizontal data center scalability. 

The Nodegrid Serial Console Plus (NSCP) offers 96 managed ports in a 1RU rack-mounted form factor, reducing the number of OOB devices needed to control large-scale data center infrastructure. Its open, x86 Linux-based OS can run VMs, VNFs, and Docker containers so teams can run virtualized workloads without deploying additional hardware. Nodegrid can also run automation, AIOps, and security on the same platform to further reduce hardware overhead.

Nodegrid OOB is also available in a modular form factor. The Net Services Router (NSR) allows teams to add or swap modules for additional compute, storage, memory, or serial ports as the data center scales up or down.

financial services

The banking and financial services industry deals with enormous, highly sensitive datasets collected from remote sites like branches, ATMs, and mobile applications. Efficiently leveraging this data while avoiding regulatory, security, and reliability issues is extremely challenging when the hardware and software resources used to analyze that data reside in the cloud or a centralized data center.

Edge computing decentralizes computing resources and distributes them at the network’s “edges,” where most banking operations take place. Running applications and leveraging data at the edge enables real-time analysis and insights, mitigates many security and compliance concerns, and ensures that systems remain operational even if Internet access is disrupted. This blog describes four edge computing use cases in banking, lists the benefits of edge computing for the financial services industry, and provides advice for ensuring the resilience, scalability, and efficiency of edge computing deployments.

4 Edge computing use cases in banking

1. AI-powered video surveillance

PCI DSS requires banks to monitor key locations with video surveillance, review and correlate surveillance data on a regular basis, and retain videos for at least 90 days. Constantly monitoring video surveillance feeds from bank branches and ATMs with maximum vigilance is nearly impossible for humans, but machines excel at it. Financial institutions are beginning to adopt artificial intelligence solutions that can analyze video feeds and detect suspicious activity with far greater vigilance and accuracy than human security personnel.

When these AI-powered surveillance solutions are deployed at the edge, they can analyze video feeds in real time, potentially catching a crime as it occurs. Edge computing also keeps surveillance data on-site, reducing bandwidth costs and network latency while mitigating the security and compliance risks involved with storing videos in the cloud.

2. Branch customer insights

Banks collect a lot of customer data from branches, web and mobile apps, and self-service ATMs. Feeding this data into AI/ML-powered data analytics software can provide insights into how to improve the customer experience and generate more revenue. By running analytics at the edge rather than from the cloud or centralized data center, banks can get these insights in real-time, allowing them to improve customer interactions while they’re happening.

For example, edge-AI/ML software can help banks provide fast, personalized investment advice on the spot by analyzing a customer’s financial history, risk preferences, and retirement goals and recommending the best options. It can also use video surveillance data to analyze traffic patterns in real-time and ensure tellers are in the right places during peak hours to reduce wait times.

3. On-site data processing

Because the financial services industry is so highly regulated, banks must follow strict security and privacy protocols to protect consumer data from malicious third parties. Transmitting sensitive financial data to the cloud or data center for processing increases the risk of interception and makes it more challenging to meet compliance requirements for data access logging and security controls.

Edge computing allows financial institutions to leverage more data on-site, within the network security perimeter. For example, loan applications contain a lot of sensitive and personally identifiable information (PII). Processing these applications on-site significantly reduces the risk of third-party interception and allows banks to maintain strict control over who accesses data and why, which is more difficult in cloud and colocation data center environments.

4. Enhanced AIOps capabilities

Financial institutions use AIOps (artificial intelligence for IT operations) to analyze monitoring data from IT devices, network infrastructure, and security solutions and get automated incident management, root-cause analysis (RCA), and simple issue remediation. Deploying AIOps at the edge provides real-time issue detection and response, significantly shortening the duration of outages and other technology disruptions. It also ensures continuous operation even if an ISP outage or network failure cuts a branch off from the cloud or data center, further helping to reduce disruptions and remote sites.

Additionally, AIOps and other artificial intelligence technology tend to use GPUs (graphics processing units), which are more expensive than CPUs (central processing units), especially in the cloud. Deploying AIOps on small, decentralized, multi-functional edge computing devices can help reduce costs without sacrificing functionality. For example, deploying an array of Nvidia A100 GPUs to handle AIOps workloads costs at least $10k per unit; comparable AWS GPU instances can cost between $2 and $3 per unit per hour. By comparison, a Nodegrid Gate SR costs under $5k and also includes remote serial console management, OOB, cellular failover, gateway routing, and much more.

The benefits of edge computing for banking

Edge computing can help the financial services industry:

  • Reduce losses, theft, and crime by leveraging artificial intelligence to analyze real-time video surveillance data.
  • Increase branch productivity and revenue with real-time insights from security systems, customer experience data, and network infrastructure.
  • Simplify regulatory compliance by keeping sensitive customer and financial data on-site within company-owned infrastructure.
  • Improve resilience with real-time AIOps capabilities like automated incident remediation that continues operating even if the site is cut off from the WAN or Internet
  • Reduce the operating costs of AI and machine learning applications by deploying them on small, multi-function edge computing devices. 
  • Mitigate the risk of interception by leveraging financial and IT data on the local network and distributing the attack surface.

Edge computing best practices

Isolating the management interfaces used to control network infrastructure is the best practice for ensuring the security, resilience, and efficiency of edge computing deployments. CISA and PCI DSS 4.0 recommend implementing isolated management infrastructure (IMI) because it prevents compromised accounts, ransomware, and other threats from laterally moving from production resources to the control plane.

IMI with Nodegrid(2)

Using vendor-neutral platforms to host, connect, and secure edge applications and workloads is the best practice for ensuring the scalability and flexibility of financial edge architectures. Moving away from dedicated device stacks and taking a “platformization” approach allows financial institutions to easily deploy, update, and swap out applications and capabilities on demand. Vendor-neutral platforms help reduce hardware overhead costs to deploy new branches and allow banks to explore different edge software capabilities without costly hardware upgrades.

Edge-Management-980×653

Additionally, using a centralized, cloud-based edge management and orchestration (EMO) platform is the best practice for ensuring remote teams have holistic oversight of the distributed edge computing architecture. This platform should be vendor-agnostic to ensure complete coverage over mixed and legacy architectures, and it should use out-of-band (OOB) management to provide continuous remote access to edge infrastructure even during a major service outage.

How Nodegrid streamlines edge computing for the banking industry

Nodegrid is a vendor-neutral edge networking platform that consolidates an entire edge tech stack into a single, cost-effective device. Nodegrid has a Linux-based OS that supports third-party VMs and Docker containers, allowing banks to run edge computing workloads, data analytics software, automation, security, and more. 

The Nodegrid Gate SR is available with an Nvidia Jetson Nano card that’s optimized for artificial intelligence workloads. This allows banks to run AI surveillance software, ML-powered recommendation engines, and AIOps at the edge alongside networking and infrastructure workloads rather than purchasing expensive, dedicated GPU resources. Plus, Nodegrid’s Gen 3 OOB management ensures continuous remote access and IMI for improved branch resilience.

ZPE Systems – AI Data Center Infrastructure
Artificial intelligence is transforming business operations across nearly every industry, with the recent McKinsey global survey finding that 72% of organizations had adopted AI, and 65% regularly use generative AI (GenAI) tools specifically. GenAI and other artificial intelligence technologies are extremely resource-intensive, requiring more computational power, data storage, and energy than traditional workloads. AI data center infrastructure also requires high-speed, low-latency networking connections and unified, scalable management hardware to ensure maximum performance and availability. This post describes the key components of AI data center infrastructure before providing advice for overcoming common pitfalls to improve the efficiency of AI deployments.

AI data center infrastructure components

A diagram of AI data center infrastructure.

Computing

Generative AI and other artificial intelligence technologies require significant processing power. AI workloads typically run on graphics processing units (GPUs), which are made up of many smaller cores that perform simple, repetitive computing tasks in parallel. GPUs can be clustered together to process data for AI much faster than CPUs.

Storage

AI requires vast amounts of data for training and inference. On-premises AI data centers typically use object storage systems with solid-state disks (SSDs) composed of multiple sections of flash memory (a.k.a., flash storage). Storage solutions for AI workloads must be modular so additional capacity can be added as data needs grow, through either physical or logical (networking) connections between devices.

Networking

AI workloads are often distributed across multiple computing and storage nodes within the same data center. To prevent packet loss or delays from affecting the accuracy or performance of AI models, nodes must be connected with high-speed, low-latency networking. Additionally, high-throughput WAN connections are needed to accommodate all the data flowing in from end-users, business sites, cloud apps, IoT devices, and other sources across the enterprise.

Power

AI infrastructure uses significantly more power than traditional data center infrastructure, with a rack of three or four AI servers consuming as much energy as 30 to 40 standard servers. To prevent issues, these power demands must be accounted for in the layout design for new AI data center deployments and, if necessary, discussed with the colocation provider to ensure enough power is available.

Management

Data center infrastructure, especially at the scale required for AI, is typically managed with a jump box, terminal server, or serial console that allows admins to control multiple devices at once. The best practice is to use an out-of-band (OOB) management device that separates the control plane from the data plane using alternative network interfaces. An OOB console server provides several important functions:

  1. It provides an alternative path to data center infrastructure that isn’t reliant on the production ISP, WAN, or LAN, ensuring remote administrators have continuous access to troubleshoot and recover systems faster, without an on-site visit.
  2. It isolates management interfaces from the production network, preventing malware or compromised accounts from jumping over from an infected system and hijacking critical data center infrastructure.
  3. It helps create an isolated recovery environment where teams can clean and rebuild systems during a ransomware attack or other breach without risking reinfection.

An OOB serial console helps minimize disruptions to AI infrastructure. For example, teams can use OOB to remotely control PDU outlets to power cycle a hung server. Or, if a networking device failure brings down the LAN, teams can use a 5G cellular OOB connection to troubleshoot and fix the problem. Out-of-band management reduces the need for costly, time-consuming site visits, which significantly improves the resilience of AI infrastructure.

AI data center challenges

Artificial intelligence workloads, and the data center infrastructure needed to support them, are highly complex. Many IT teams struggle to efficiently provision, maintain, and repair AI data center infrastructure at the scale and speed required, especially when workflows are fragmented across legacy and multi-vendor solutions that may not integrate. The best way to ensure data center teams can keep up with the demands of artificial intelligence is with a unified AI orchestration platform. Such a platform should include:

  • Automation for repetitive provisioning and troubleshooting tasks
  • Unification of all AI-related workflows with a single, vendor-neutral platform
  • Resilience with cellular failover and Gen 3 out-of-band management.

AI Orchestration(1)
Generative AI and other artificial intelligence technologies are still surging in popularity across every industry, with the recent McKinsey global survey finding that 72% of organizations had adopted AI in at least one business function. In the rush to capitalize on the potential productivity and financial gains promised by AI solution providers, technology leaders are facing new challenges relating to deploying, supporting, securing, and scaling AI workloads and infrastructure. These challenges are exacerbated by the fragmented nature of many enterprise IT environments, with administrators overseeing many disparate, vendor-specific solutions that interoperate poorly if at all.

The goal of AI orchestration is to provide a single, unified platform for teams to oversee and manage AI-related workflows across the entire organization. This post describes the ideal AI orchestration solution and the technologies that make it work, helping companies use artificial intelligence more efficiently.

AI challenges to overcome

The challenges an organization must overcome to use AI more cost-effectively and see faster returns can be broken down into three categories:

  1. Overseeing AI-led workflows to ensure models are behaving as expected and providing accurate results, when these workflows are spread across the enterprise in different geographic locations and vendor-specific applications.
    .
  2. Efficiently provisioning, maintaining, and scaling the vast infrastructure and computational resources required to run intensive AI workflows at remote data centers and edge computing sites.
    .
  3. Maintaining 24/7 availability and performance of remote AI workflows and infrastructure during security breaches, equipment failures, network outages, and natural disasters.

These challenges have a few common causes. One is that artificial intelligence and the underlying infrastructure that supports it are highly complex, making it difficult for human engineers to keep up. Two is that many IT environments are highly fragmented due to closed vendor solutions that integrate poorly and require administrators to manage too many disparate systems, allowing coverage gaps to form. Three is that many AI-related workloads occur off-site at data centers and edge computing sites, so it’s harder for IT teams to repair and recover AI systems that go down due to a networking outage, equipment failure, or other disruptive event.

How AI orchestration streamlines AI/ML in an enterprise environment

The ideal AI orchestration platform solves these problems by automating repetitive and data-heavy tasks, unifying workflows with a vendor-neutral platform, and using out-of-band (OOB) serial console management to provide continuous remote access even during major outages.

Automation

Automation is crucial for teams to keep up with the pace and scale of artificial intelligence. Organizations use automation to provision and install AI data center infrastructure, manage storage for AI training and inference data, monitor inputs and outputs for toxicity, perform root-cause analyses when systems fail, and much more. However, tracking and troubleshooting so many automated workflows can get very complicated, creating more work for administrators rather than making them more productive. An AI orchestration platform should provide a centralized interface for teams to deploy and oversee automated workflows across applications, infrastructure, and business sites.

Unification

The best way to improve AI operational efficiency is to integrate all of the complicated monitoring, management, automation, security, and remediation workflows. This can be accomplished by choosing solutions and vendors that interoperate or, even better, are completely vendor-agnostic (a.k.a., vendor-neutral). For example, using open, common platforms to run AI workloads, manage AI infrastructure, and host AI-related security software can help bring everything together where administrators have easy access. An AI orchestration platform should be vendor-neutral to facilitate workload unification and streamline integrations.

Resilience

AI models, workloads, and infrastructure are highly complex and interconnected, so an issue with one component could compromise interdependencies in ways that are difficult to predict and troubleshoot. AI systems are also attractive targets for cybercriminals due to their vast, valuable data sets and because of how difficult they are to secure, with HiddenLayer’s 2024 AI Threat Landscape Report finding that 77% of businesses have experienced AI-related breaches in the last year. An AI orchestration platform should help improve resilience, or the ability to continue operating during adverse events like tech failures, breaches, and natural disasters.

Gen 3 out-of-band management technology is a crucial component of AI and network resilience. A vendor-neutral OOB solution like the Nodegrid Serial Console Plus (NSCP) uses alternative network connections to provide continuous management access to remote data center, branch, and edge infrastructure even when the ISP, WAN, or LAN connection goes down. This gives administrators a lifeline to troubleshoot and recover AI infrastructure without costly and time-consuming site visits. The NSCP allows teams to remotely monitor power consumption and cooling for AI infrastructure. It also provides 5G/4G LTE cellular failover so organizations can continue delivering critical services while the production network is repaired.

A diagram showing isolated management infrastructure with the Nodegrid Serial Console Plus.

Gen 3 OOB also helps organizations implement isolated management infrastructure (IMI), a.k.a, control plane/data plane separation. This is a cybersecurity best practice recommended by the CISA as well as regulations like PCI DSS 4.0, DORA, NIS2, and the CER Directive. IMI prevents malicious actors from being able to laterally move from a compromised production system to the management interfaces used to control AI systems and other infrastructure. It also provides a safe recovery environment where teams can rebuild and restore systems during a ransomware attack or other breach without risking reinfection.

Getting the most out of your AI investment

An AI orchestration platform should streamline workflows with automation, provide a unified platform to oversee and control AI-related applications and systems for maximum efficiency and coverage, and use Gen 3 OOB to improve resilience and minimize disruptions. Reducing management complexity, risk, and repair costs can help companies see greater productivity and financial returns from their AI investments.

The vendor-neutral Nodegrid platform from ZPE Systems provides highly scalable Gen 3 OOB management for up to 96 devices with a single, 1RU serial console. The open Nodegrid OS also supports VMs and Docker containers for third-party applications, so you can run AI, automation, security, and management workflows all from the same device for ultimate operational efficiency.

This blog describes four edge computing use cases in telecom before describing the benefits and best practices for the telecommunications industry.
Telecommunications networks are vast and extremely distributed, with critical network infrastructure deployed at core sites like Internet exchanges and data centers, business and residential customer premises, and access sites like towers, street cabinets, and cell site shelters. This distributed nature lends itself well to edge computing, which involves deploying computing resources like CPUs and storage to the edges of the network where the most valuable telecom data is generated. Edge computing allows telecom companies to leverage data from CPE, networking devices, and users themselves in real-time, creating many opportunities to improve service delivery, operational efficiency, and resilience.

This blog describes four edge computing use cases in telecom before describing the benefits and best practices for edge computing in the telecommunications industry.

4 Edge computing use cases in telecom

1. Enhancing the customer experience with real-time analytics

Each customer interaction, from sales calls to repair requests and service complaints, is a chance to collect and leverage data to improve the experience in the future. Transferring that data from customer sites, regional branches, and customer service centers to a centralized data analysis application takes time, creates network latency, and can make it more difficult to get localized and context-specific insights. Edge computing allows telecom companies to analyze valuable customer experience data, such as network speed, uptime (or downtime) count, and number of support contacts in real-time, providing better opportunities to identify and correct issues before they go on to affect future interactions.

2. Streamlining remote infrastructure management and recovery with AIOps

AIOps helps telecom companies manage complex, distributed network infrastructure more efficiently. AIOps (artificial intelligence for IT operations) uses advanced machine learning algorithms to analyze infrastructure monitoring data and provide maintenance recommendations, automated incident management, and simple issue remediation. Deploying AIOps on edge computing devices at each telecom site enables real-time analysis, detection, and response, helping to reduce the duration of service disruptions. For example, AIOps can perform automated root-cause analysis (RCA) to help identify the source of a regional outage before technicians arrive on-site, allowing them to dive right into the repair. Edge AIOps solutions can also continue functioning even if the site is cut off from the WAN or Internet, potentially self-healing downed networks without the need to deploy repair techs on-site.

3. Preventing environmental conditions from damaging remote equipment

Telecommunications equipment is often deployed in less-than-ideal operating conditions, such as unventilated closets and remote cell site shelters. Heat, humidity, and air particulates can shorten the lifespan of critical equipment or cause expensive service failures, which is why it’s recommended to use environmental monitoring sensors to detect and alert remote technicians to problems. Edge computing applications can analyze environmental monitoring data in real-time and send alerts to nearby personnel much faster than cloud- or data center-based solutions, ensuring major fluctuations are corrected before they damage critical equipment.

4. Improving operational efficiency with network virtualization and consolidation

Another way to reduce management complexity – as well as overhead and operating expenses – is through virtualization and consolidation. Network functions virtualization (NFV) virtualizes networking equipment like load balancers, firewalls, routers, and WAN gateways, turning them into software that can be deployed anywhere – including edge computing devices. This significantly reduces the physical tech stack at each site, consolidating once-complicated network infrastructure into, in some cases, a single device. For example, the Nodegrid Gate SR provides a vendor-neutral edge computing platform that supports third-party NFVs while also including critical edge networking functionality like out-of-band (OOB) serial console management and 5G/4G cellular failover.

Edge computing in telecom: Benefits and best practices

Edge computing can help telecommunications companies:

  • Get actionable insights that can be leveraged in real-time to improve network performance, service reliability, and the support experience.
  • Reduce network latency by processing more data at each site instead of transmitting it to the cloud or data center for analysis.
  • Lower CAPEX and OPEX at each site by consolidating the tech stack and automating management workflows with AIOps.
  • Prevent downtime with real-time analysis of environmental and equipment monitoring data to catch problems before they escalate.
  • Accelerate recovery with real-time, AIOps root-cause analysis and simple incident remediation that continues functioning even if the site is cut off from the WAN or Internet.

Management infrastructure isolation, which is recommended by CISA and required by regulations like DORA, is the best practice for improving edge resilience and ensuring a speedy recovery from failures and breaches. Isolated management infrastructure (IMI) prevents compromised accounts, ransomware, and other threats from moving laterally from production resources to the interfaces used to control critical network infrastructure.

IMI with Nodegrid(2)
To ensure the scalability and flexibility of edge architectures, the best practice is to use vendor-neutral platforms to host, connect, and secure edge applications and workloads. Moving away from dedicated device stacks and taking a “platformization” approach allows organizations to easily deploy, update, and swap out functions and services on demand. For example, Nodegrid edge networking solutions have a Linux-based OS that supports third-party VMs, Docker containers, and NFVs. Telecom companies can use Nodegrid to run edge computing workloads as well as asset management software, customer experience analytics, AIOps, and edge security solutions like SASE.

Vendor-neutral platforms help reduce hardware overhead costs to deploy new edge sites, make it easy to spin-up new NFVs to meet increased demand, and allow telecom organizations to explore different edge software capabilities without costly hardware upgrades. For example, the Nodegrid Gate SR is available with an Nvidia Jetson Nano card that’s optimized for AI workloads, so companies can run innovative artificial intelligence at the edge alongside networking and infrastructure management workloads rather than purchasing expensive, dedicated GPU resources.

Edge-Management-980×653
Finally, to ensure teams have holistic oversight of the distributed edge computing architecture, the best practice is to use a centralized, cloud-based edge management and orchestration (EMO) platform. This platform should also be vendor-neutral to ensure complete coverage and should use out-of-band management to provide continuous management access to edge infrastructure even during a major service outage.

Automated transportation robots move boxes in a warehouse, one of many edge computing use cases in retail
Retail organizations must constantly adapt to meet changing customer expectations, mitigate external economic forces, and stay ahead of the competition. Technologies like the Internet of Things (IoT), artificial intelligence (AI), and other forms of automation help companies improve the customer experience and deliver products at the pace demanded in the age of one-click shopping and two-day shipping. However, connecting individual retail locations to applications in the cloud or centralized data center increases network latency, security risks, and bandwidth utilization costs.

Edge computing mitigates many of these challenges by decentralizing cloud and data center resources and distributing them at the network’s “edges,” where most retail operations take place. Running applications and processing data at the edge enables real-time analysis and insights and ensures that systems remain operational even if Internet access is disrupted by an ISP outage or natural disaster. This blog describes five potential edge computing use cases in retail and provides more information about the benefits of edge computing for the retail industry.

Security cameras are crucial to loss prevention, but constantly monitoring video surveillance feeds is tedious and difficult for even the most experienced personnel. AI-powered video surveillance systems use machine learning to analyze video feeds and detect suspicious activity with greater vigilance and accuracy. Edge computing enhances AI surveillance by allowing solutions to analyze video feeds in real-time, potentially catching shoplifters in the act and preventing inventory shrinkage.

2. Localized, real-time insights

Retailers have a brief window to meet a customer’s needs before they get frustrated and look elsewhere, especially in a brick-and-mortar store. A retail store can use an edge computing application to learn about customer behavior and purchasing activity in real-time. For example, they can use this information to rotate the products featured on aisle endcaps to meet changing demand, or staff additional personnel in high-traffic departments at certain times of day. Stores can also place QR codes on shelves that customers scan if a product is out of stock, immediately alerting a nearby representative to provide assistance.

3. Enhanced inventory management

Effective inventory management is challenging even for the most experienced retail managers, but ordering too much or too little product can significantly affect sales. Edge computing applications can improve inventory efficiency by making ordering recommendations based on observed purchasing patterns combined with real-time stocking updates as products are purchased or returned. Retailers can use this information to reduce carrying costs for unsold merchandise while preventing out-of-stocks, improving overall profit margins.
.

4. Building management

Using IoT devices to monitor and control building functions such as HVAC, lighting, doors, power, and security can help retail organizations reduce the need for on-site facilities personnel, and make more efficient use of their time. Data analysis software helps automatically optimize these systems for efficiency while ensuring a comfortable customer experience. Running this software at the edge allows automated processes to respond to changing conditions in real-time, for example, lowering the A/C temperature or routing more power to refrigerated cases during a heatwave.

5. Warehouse automation

The retail industry uses warehouse automation systems to improve the speed and efficiency at which goods are delivered to stores or directly to users. These systems include automated storage and retrieval systems, robotic pickers and transporters, and automated sortation systems. Companies can use edge computing applications to monitor, control, and maintain warehouse automation systems with minimal latency. These applications also remain operational even if the site loses internet access, improving resilience.

Edge computing benefits

Description

Reduced latency

Edge computing decreases the number of network hops between devices and the applications they rely on, reducing latency and improving the speed and reliability of retail technology at the edge.

Real-time insights

Edge computing can analyze data in real-time and provide actionable insights to improve the customer experience before a sale is lost or reduce waste before monthly targets are missed.

Improved resilience

Edge computing applications can continue functioning even if the site loses Internet or WAN access, enabling continuous operations and reducing the costs of network downtime.

Risk mitigation

Keeping sensitive internal data like personnel records, sales numbers, and customer loyalty information on the local network mitigates the risk of interception and distributes the attack surface.

Edge computing can also help retail companies lower their operational costs at each site by reducing bandwidth utilization on expensive MPLS links and decreasing expenses for cloud data storage and computing. Another way to lower costs is by using consolidated, vendor-neutral solutions to run, connect, and secure edge applications and workloads.

For example, the Nodegrid Gate SR integrated branch services router delivers an entire stack of edge networking, infrastructure management, and computing technologies in a single, streamlined device. The open, Linux-based Nodegrid OS supports VMs and Docker containers for third-party edge computing applications, security solutions, and more. The Gate SR is also available with an Nvidia Jetson Nano card that’s optimized for AI workloads to help retail organizations reduce the hardware overhead costs of deploying artificial intelligence at the edge.

A closeup of an IoT pulse oximeter, one of many edge computing use cases in healthcare
The healthcare industry enthusiastically adopted Internet of Things (IoT) technology to improve diagnostics, health monitoring, and overall patient outcomes. The data generated by healthcare IoT devices is processed and used by sophisticated data analytics and artificial intelligence applications, which traditionally live in the cloud or a centralized data center. Transmitting all this sensitive data back and forth is inefficient and increases the risk of interception or compliance violations.

Edge computing deploys data analytics applications and computing resources around the edges of the network, where much of the most valuable data is created. This significantly reduces latency and mitigates many security and compliance risks. In a healthcare setting, edge computing enables real-time medical insights and interventions while keeping HIPAA-regulated data within the local security perimeter. This blog describes six potential edge computing use cases in healthcare that take advantage of the speed and security of an edge computing architecture.

6 Edge computing use cases in healthcare

Edge computing use cases for EMS

Mobile emergency medical services (EMS) teams need to make split-second decisions regarding patient health without the benefit of a doctorate and, often, with spotty Internet connections preventing access to online drug interaction guides and other tools. Installing edge computing resources on cellular edge routers gives EMS units real-time health analysis capabilities as well as a reliable connection for research and communications. Potential use cases include:
.

Use cases

Description

1. Real-time health analysis en route

Edge computing applications can analyze data from health monitors in real-time and access available medical records to help medics prevent allergic reactions and harmful medication interactions while administering treatment.

2. Prepping the ER with patient health insights

Some edge computing devices use 5G/4G cellular to livestream patient data to the receiving hospital, so ER staff can make the necessary arrangements and begin the proper treatment as soon as the patient arrives.

Edge computing use cases in hospitals & clinics

Hospitals and clinics use IoT devices to monitor vitals, dispense medications, perform diagnostic tests, and much more. Sending all this data to the cloud or data center takes time, delaying test results or preventing early intervention in a health crisis, especially in rural locations with slow or spotty Internet access. Deploying applications and computing resources on the same local network enables faster analysis and real-time alerts. Potential use cases include:
.

Use cases

Description

3. AI-powered diagnostic analysis

Edge computing allows healthcare teams to use AI-powered tools to analyze imaging scans and other test results without latency or delays, even in remote clinics with limited Internet infrastructure.

4. Real-time patient monitoring alerts

Edge computing applications can analyze data from in-room monitoring devices like pulse oximeters and body thermometers in real-time, spotting early warning signs of medical stress and alerting staff before serious complications arise.

Edge computing use cases for wearable medical devices

Wearable medical devices give patients and their caregivers greater control over health outcomes. With edge computing, health data analysis software can run directly on the wearable device, providing real-time results even without an Internet connection. Potential use cases include:
.

Use cases

Description

5. Continuous health monitoring

An edge-native application running on a system-on-chip (SoC) in a wearable insulin pump can analyze levels in real-time and provide recommendations on how to correct imbalances before they become dangerous.

6. Real-time emergency alerts

Edge computing software running on an implanted heart-rate monitor can give a patient real-time alerts when activity falls outside of an established baseline, and, in case of emergency, use cellular and ATT FirstNet connections to notify medical staff.

The benefits of edge computing for healthcare

Using edge computing in a healthcare setting as described in the use cases above can help organizations:

  • Improve patient care in remote settings, where a lack of infrastructure limits the ability to use cloud-based technology solutions.
  • Process and analyze patient health data faster and more reliably, leading to earlier interventions.
  • Increase efficiency by assisting understaffed medical teams with diagnostics, patient monitoring, and communications.
  • Mitigate security and compliance risks by keeping health data within the local security perimeter.

Edge computing can also help healthcare organizations lower their operational costs at the edge by reducing bandwidth utilization and cloud data storage expenses. Another way to reduce costs is by using consolidated, vendor-neutral solutions to host, connect, and secure edge applications and workloads.

For example, the Nodegrid Gate SR is an integrated branch services router that delivers an entire stack of edge networking, infrastructure management, and computing technologies in a single, streamlined device. Nodegrid’s open, Linux-based OS supports VMs and Docker containers for third-party edge applications, security solutions, and more.

An illustration showing various use cases and benefits of edge computing

Edge computing delivers data processing and analysis capabilities to the network’s “edge,” at remote sites like branch offices, warehouses, retail stores, and manufacturing plants. It involves deploying computing resources and lightweight applications very near the devices that generate data, reducing the distance and number of network hops between them. In doing so, edge computing reduces latency and bandwidth costs while mitigating risk, enhancing edge resilience, and enabling real-time insights. This blog discusses the five biggest benefits of edge computing, providing examples and additional resources for companies beginning their edge journey.
.

5 benefits of edge computing​

Edge Computing:

Description

Reduces latency

Leveraging data at the edge reduces network hops and latency to improve speed and performance.

Mitigates risk

Keeping data on-site at distributed edge locations reduces the chances of interception and limits the blast radius of breaches.

Lowers bandwidth costs

Reducing edge data transmissions over expensive MPLS lines helps keep branch costs low.

Enhances edge resilience

Analyzing data on-site ensures that edge operations can continue uninterrupted during ISP outages and natural disasters.

Enables real-time insights

Eliminating off-site processing allows companies to use and extract value from data as soon as it’s generated.

1. Reduces latency

Edge computing leverages data on the same local network as the devices that generate it, cutting down on edge data transmissions over the WAN or Internet. Reducing the number of network hops between devices and applications significantly decreases latency, improving the speed and performance of business intelligence apps, AIOps, equipment health analytics, and other solutions that use edge data.

Some edge applications run on the devices themselves, completely eliminating network hops and facilitating real-time, lag-free analysis. For example, an AI-powered surveillance application installed on an IoT security camera at a walk-up ATM can analyze video feeds in real-time and alert security personnel to suspicious activity as it occurs.​

 

Read more examples of how edge computing improves performance in our guide to the Applications of Edge Computing.

2. Mitigates risk

Edge computing mitigates security and compliance risks by distributing an organization’s sensitive data and reducing off-site transmission. Large, centralized data stores in the cloud or data center are prime targets for cybercriminals because the sheer volume of data involved increases the chances of finding something valuable. Decentralizing data in much smaller edge storage solutions makes it harder for hackers to find the most sensitive information and also limits how much data they can access at one time.

Keeping data at the edge also reduces the chances of interception in transit to cloud or data center storage. Plus, unlike in the cloud, an organization maintains complete control over who and what has access to sensitive data, aiding in compliance with regulations like the GDPR and PCI DSS 4.0.
.

To learn how to protect edge data and computing resources, read Comparing Edge Security Solutions.

3. Lowers bandwidth costs

Many organizations use MPLS (multi-protocol label switching) links to securely connect edge sites to the enterprise network. MPLS bandwidth is much more expensive than regular Internet lines, which makes transmitting edge data to centralized data processing applications extremely costly. Plus, it can take months to provision MPLS at a new site, delaying launches and driving up overhead expenses.

Edge computing significantly reduces MPLS bandwidth utilization by running data-hungry applications on the local network, reserving the WAN for other essential traffic. Combining edge computing with SD-WAN (software-defined wide area networking) and SASE (secure access service edge) technologies can markedly decrease the reliance on MPLS links, allowing organizations to accelerate branch openings and see faster edge ROIs.
.

Learn more about cost-effective edge deployments in our Edge Computing Architecture Guide.

4. Enhances edge resilience

Since edge computing applications run on the same LAN as the devices generating data, they can continue to function even if the site loses Internet access due to an ISP outage, natural disaster, or other adverse event. This also allows uninterrupted edge operations in locations with inconsistent (or no) Internet coverage, like offshore oil rigs, agricultural sites, and health clinics in isolated rural communities. Edge computing ensures that organizations don’t miss any vital health or safety alerts and facilitates technological innovation using AI and other data analytics tools in challenging environments..
.

For more information on operational resilience, read Network Resilience: What is a Resilience System?

5. Enables real-time insights

Sending data from the edge to a cloud or on-premises data lake for processing, transformation, and ingestion by analytics or AI/ML tools takes time, preventing companies from acting on insights at the moment when they’re most useful. Edge computing applications start using data as soon as it’s generated, so organizations can extract value from it right away. For example, a retail store can use edge computing to gain actionable insights on purchasing activity and customer behavior in real-time, so they can move in-demand products to aisle endcaps or staff extra cashiers as needed.

Improving Your Zero Trust Security Posture https://zpesystems.com/zero-trust-security-posture-zs/ Tue, 16 Jul 2024 19:51:31 +0000 https://zpesystems.com/?p=225257 This blog provides advice for improving your zero trust security posture with a multi-layered strategy that mitigates weaknesses for complete coverage.

The post Improving Your Zero Trust Security Posture appeared first on ZPE Systems.

Zero Trust for the Edge(1)

The current cyber threat landscape is daunting, with attacks occurring so frequently that security experts recommend operating under the assumption that your network is already breached. Major cyber attacks – and the disruptions they cause – frequently make news headlines. For example, the recent LendingTree breach exposed consumer data, which could affect the company’s reputation and compliance status. An attack on auto dealership software company CDK Global took down the platform and disrupted business for approximately 15,000 car sellers – an outage that’s still ongoing as of this article’s writing.

The zero trust security methodology outlines the best practices for limiting the blast radius of a successful breach by preventing malicious actors from moving laterally through the network and accessing the most valuable or sensitive resources. Many organizations have already begun their zero trust journey by implementing role-based access controls (RBAC), multi-factor authentication (MFA), and other security solutions, but still struggle with coverage gaps that result in ransomware attacks and other disruptive breaches. This blog provides advice for improving your zero trust security posture with a multi-layered strategy that mitigates weaknesses for complete coverage.

How to improve your zero trust security posture

.

Strategy

Description

Gain a full understanding of your protect surface

Use automated discovery tools to identify all the data, assets, applications, and services that an attacker could potentially target.

Micro-segment your network with micro-perimeters

Implement specific policies, controls, and trust verification mechanisms to mitigate and protect surface vulnerabilities.

Isolate and defend your management infrastructure

Use OOB management and hardware security to prevent attackers from compromising the control plane.

Defend your cloud resources

Understand the shared responsibility model and use cloud-specific tools like a CASB to prevent shadow IT and enforce zero trust.

Extend zero trust to the edge

Use edge-centric solutions like SASE to extend zero trust policies and controls to remote network traffic, devices, and users.

Gain a full understanding of your protect surface

Many security strategies focus on defending the network’s “attack surface,” or all the potential vulnerabilities an attacker could exploit to breach the network. However, zero trust is all about defending the “protect surface,” or all the data, assets, applications, and services that an attacker could potentially try to access. The key difference is that zero trust doesn’t ask you to try to cover any possible weakness in a network, which is essentially impossible. Instead, it wants you to look at the resources themselves to determine what has the most value to an attacker, and then implement security controls that are tailored accordingly.

Gaining a full understanding of all the resources on your network can be extraordinarily challenging, especially with the proliferation of SaaS apps, mobile devices, and remote workforces. There are automated tools that can help IT teams discover all the data, apps, and devices on the network. Application discovery and dependency mapping (ADDM) tools help identify all on-premises software and third-party dependencies; cloud application discovery tools do the same for cloud-hosted apps by monitoring network traffic to cloud domains. Sensitive data discovery tools scan all known on-premises or cloud-based resources for personally identifiable information (PII) and other confidential data, and there are various device management solutions to detect network-connected hardware, including IoT devices.
,

  • Tip: This step can’t be completed one time and then forgotten – teams should execute discovery processes on a regular, scheduled basis to limit gaps in protection. 

Micro-segment your network with micro-perimeters

Micro-segmentation is a cornerstone of zero-trust networks. It involves logically separating all the data, applications, assets, and services according to attack value, access needs, and interdependencies. Then, teams implement granular security policies and controls tailored to the needs of each segment, establishing what are known as micro-perimeters. Rather than trying to account for every potential vulnerability with one large security perimeter, teams can just focus on the tools and policies needed to cover the specific vulnerabilities of a particular micro-segment.

Network micro-perimeters help improve your zero trust security posture with:

  • Granular access policies granting the least amount of privileges needed for any given workflow. Limiting the number of accounts with access to any given resource, and limiting the number of privileges granted to any given account, significantly reduces the amount of damage a compromised account (or malicious actor) is capable of inflicting.
  • Targeted security controls addressing the specific risks and vulnerabilities of the resources in a micro-segment. For example, financial systems need stronger encryption, strict data governance monitoring, and multiple methods of trust verification, whereas an IoT lighting system requires simple monitoring and patch management, so the security controls for these micro-segments should be different.
  • Trust verification using context-aware policies to catch accounts exhibiting suspicious behavior and prevent them from accessing sensitive resources. If a malicious outsider compromises an authorized user account and MFA device – or a disgruntled employee uses their network privileges to harm the company – it can be nearly impossible to prevent data exposure. Context-aware policies can stop a user from accessing confidential resources outside of typical operating hours, or from unfamiliar IP addresses, for example. Additionally, user entity and behavior analytics (UEBA) solutions use machine learning to detect other abnormal and risky behaviors that could indicate malicious intent.

Isolate and defend your management infrastructure

For zero trust to be effective, organizations must apply consistently strict security policies and controls to every component of their network architecture, including the management interfaces used to control infrastructure. Otherwise, a malicious actor could use a compromised sysadmin account to hijack the control plane and bring down the entire network.

According to a recent CISA directive, the best practice is to isolate the network’s control plane so that management interfaces are inaccessible from the production network. Many new cybersecurity regulations, including PCI DSS 4.0, DORA, NIS2, and the CER Directive, also either strongly recommend or require management infrastructure isolation.

Isolated management infrastructure (IMI) prevents compromised accounts, ransomware, and other threats from moving laterally to or from the production LAN. It gives teams a safe environment to recover from ransomware or other cyberattacks without risking reinfection, which is known as an isolated recovery environment (IRE). Management interfaces and the IRE should also be protected by granular, role-based access policies, multi-factor authentication, and strong hardware roots of trust to further mitigate risk.

A diagram showing how to use Nodegrid Gen 3 OOB to enable IMI.The easiest and most secure way to implement IMI is with Gen 3 out-of-band (OOB) serial console servers, like the Nodegrid solution from ZPE Systems. These devices use alternative network interfaces like 5G/4G LTE cellular to ensure complete isolation and 24/7 management access even during outages. They’re protected by hardware security features like TPM 2.0 and GPS geofencing, and they integrate with zero trust solutions like identity and access management (IAM) and UEBA to enable consistent policy enforcement.

Defend your cloud resources

The vast majority of companies host some or all of their workflows in the cloud, which significantly expands and complicates the attack surface while making it more challenging to identify and defend the protect surface. Some organizations also lack a complete understanding of the shared responsibility model for varying cloud services, increasing the chances of coverage gaps. Additionally, many orgs struggle with “shadow IT,” which occurs when individual business units implement cloud applications without going through onboarding, preventing security teams from applying zero trust controls.

The first step toward improving your zero trust security posture in the cloud is to ensure you understand where your cloud service provider’s responsibilities end and yours begin. For instance, most SaaS providers handle all aspects of security except IAM and data protection, whereas IaaS (Infrastructure-as-a-Service) providers are only responsible for protecting their physical and virtual infrastructure.

It’s also vital that security teams have a complete picture of all the cloud services in use by the organization and a way to deploy and enforce zero trust policies in the cloud. For example, a cloud access security broker (CASB) is a solution that discovers all the cloud services in use by an organization and allows teams to monitor and manage security for the entire cloud architecture. A CASB provides capabilities like data governance, malware detection, and adaptive access controls, so organizations can protect their cloud resources with the same techniques used in the on-premises environment.

Data leak prevention

Extend zero trust to the edge

Modern enterprise networks are highly decentralized, with many business operations taking place at remote branches, Internet of Things (IoT) deployment sites, and end-users’ homes. Extending security controls to the edge with on-premises zero trust solutions is very difficult without backhauling all remote traffic through a centralized firewall, which creates bottlenecks that affect performance and reliability. Luckily, the market for edge security solutions is rapidly growing and evolving to help organizations overcome these challenges. 

Security Access Service Edge (SASE) is a type of security platform that delivers core capabilities as a managed, typically cloud-based service for the edge. SASE uses software-defined wide area networking (SD-WAN) to intelligently and securely route edge traffic through the SASE tech stack, allowing the application and enforcement of zero trust controls. In addition to CASB and next-generation firewall (NGFW) features, SASE usually includes zero trust network access (ZTNA), which offers VPN-like functionality to connect remote users to enterprise resources from outside the network. ZTNA is more secure than a VPN because it only grants access to one app at a time, requiring separate authorization requests and trust verification attempts to move to different resources. 

Accelerating the zero trust journey

Zero trust is not a single security solution that you can implement once and forget about – it requires constant analysis of your security posture to identify and defend weaknesses as they arise. The best way to ensure adaptability is by using vendor-agnostic platforms to host and orchestrate zero trust security. This will allow you to add and change security services as needed without worrying about interoperability issues.

For example, the Nodegrid platform from ZPE Systems includes vendor-neutral serial consoles and integrated branch services routers that can host third-party software such as SASE and NGFWs. These devices also provide Gen 3 out-of-band management for infrastructure isolation and network resilience. Nodegrid protects management interfaces with strong hardware roots-of-trust, embedded firewalls, SAML 2.0 integrations, and other zero trust security features. Plus, with Nodegrid’s cloud-based or on-premises management platform, teams can orchestrate networking, infrastructure, and security workflows across the entire enterprise architecture.

What are edge security solutions?

Edge security solutions primarily fall into one (or both) of two categories:

  • Security Service Edge (SSE) solutions deliver core security features as a managed service. SSE does not come with any networking capabilities, so companies still need a way to securely route edge traffic through the (often cloud-based) security stack. This usually involves software-defined wide area networking (SD-WAN), which was traditionally a separate service that had to be integrated with the SSE stack.
  • Secure Access Service Edge (SASE) solutions package SSE together with SD-WAN, preventing companies from needing to deploy and manage multiple vendor solutions.

All the top SSE providers now offer fully integrated SASE solutions with SD-WAN. SASE’s main tech stack is in the cloud, but organizations must install SD-WAN appliances at each branch or edge data center. SASE also typically uses software agents deployed at each site and, in some cases, on all edge devices. Some SASE vendors also sell physical appliances, while others only provide software licenses for virtualized SD-WAN solutions. A third category of edge security solutions offers a secure platform to run other vendors’ SD-WAN and SASE software. These solutions also provide an important edge security capability: management network isolation. This feature ensures that ransomware, viruses, and malicious actors can’t jump from compromised IoT devices to the management interfaces used to control vital edge infrastructure.

Cisco

Cisco is one of the only edge security vendors to offer SASE as a managed service for companies with lean IT operations and a lack of edge networking experience. Cisco Secure Connect SASE-as-a-service includes all the usual SSE capabilities, such as ZTNA, SWG, and CASB, as well as native Meraki SD-WAN integration and a generative AI assistant. Cisco also provides traditional SASE by combining Cisco Secure Access SSE – which includes the Cisco Umbrella Secure Internet Gateway (SIG) – with Catalyst SD-WAN. Cisco Secure Connect makes SASE more accessible to smaller, less experienced IT teams, though its high price tag could be prohibitive to these companies. Cisco’s unmanaged SASE solutions integrate easily with existing Cisco infrastructures, but they offer less flexibility in the choice of features than other options on this list.

Edge isolation and security with ZPE Nodegrid

The Nodegrid platform from ZPE Systems is a different type of edge security solution, providing secure hardware and software to host other vendors’ tools on a secure, Gen 3 out-of-band (OOB) management network. Nodegrid integrated branch services routers use alternative network interfaces (including 5G/4G LTE) and serial console technology to create a control plane for edge infrastructure that’s completely isolated from breaches on the production network. It uses hardware security features like secure boot and geofencing to prevent physical tampering, and it supports strong authentication methods and SAML integrations to protect the management network. A screenshot from the Forcepoint ONE SASE solution. Nodegrid’s OOB also ensures remote teams have 24/7 access to manage, troubleshoot, and recover edge deployments even during a major network outage or ransomware infection. Plus, Nodegrid’s ability to host Guest OS, including Docker containers and VNFs, allows companies to consolidate an entire edge networking stack in a single platform. Nodegrid devices like the Gate SR with Nvidia Jetson Nano can even run edge computing and AI/ML workloads alongside SASE. .
