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.

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.

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..

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

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. The MGM hack, LendingTree breach, and CDK Global attack are just a few examples that affected thousands of people per incident and now have many organizations rethinking their resilience strategies.

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.

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.

Interlocking cogwheels containing icons of various edge computing examples are displayed in front of racks of servers

The edge computing market is growing fast, with experts predicting edge computing spending to reach almost $350 billion in 2027. Companies use edge computing to leverage data from Internet of Things (IoT) sensors and other devices at the periphery of the network in real-time, unlocking faster insights, accelerating ROIs for artificial intelligence and machine learning investments, and much more. This blog highlights 7 edge computing examples from across many different industries and provides tips and best practices for each use case.

What is edge computing?

Edge computing involves moving compute capabilities – processing units, RAM, storage, data analysis software, etc. – to the network’s edges. This allows companies to analyze or otherwise use edge data in real-time, without transmitting it to a central data center or the cloud.

Edge Computing Learning Center

Edge computing shortens the physical and logical distance between data-generating devices and the applications that use that data, which reduces bandwidth costs and network latency while simplifying many aspects of data security and compliance.

7 Edge computing examples

Below are 7 examples of how organizations use edge computing, along with best practices for overcoming the typical challenges involved in each use case. Click the links in the table for more information about each example.

Examples Best Practices
Monitoring inaccessible equipment in the oil & gas industry Use a vendor-neutral edge computing & networking platform to reduce the tech stack at each site.
Remotely managing and securing automated Smart buildings Isolate the management interfaces for automated building management systems from production to reduce risk.
Analyzing patient health data generated by mobile devices Protect patient privacy with strong hardware roots-of-trust, Zero Trust Edge integrations, and control plane/data plane separation.
Reducing latency for live streaming events and online gaming Use all-in-one, vendor-neutral devices to minimize hardware overhead and enable cost-effective scaling.
Improving performance and business outcomes for AI/ML Streamline operations by using a vendor-neutral platform to remotely monitor and orchestrate edge AI/ML deployments.
Enhancing remote surveillance capabilities at banks and ATMs Isolate the management interfaces for all surveillance systems using Gen 3 OOB to prevent compromise.
Extending data analysis to agriculture sites with limited Internet access Deploy edge gateway routers with environmental sensors to monitor operating conditions and prevent equipment failures.

1. Monitoring and managing inaccessible equipment in the oil and gas industry

The oil and gas industry uses IoT sensors to monitor flow rates, detect leaks, and gather other critical information about human-inaccessible equipment and operations. With drilling rigs located offshore and in extremely remote locations, ensuring reliable internet access to communicate with cloud-based or on-premises monitoring applications can be tricky. Dispatching IT teams to diagnose and repair issues is also costly, time-consuming, and risky. Edge computing allows oil and gas companies to process data on-site and in real-time, so safety issues and potential equipment failures are caught and remediated as soon as possible, even when Internet access is spotty.

Best practice: Use a vendor-neutral edge computing & networking platform like the Nodegrid Gate SR to reduce the tech stack at each site. The Gate SR can host other vendors’ software for SD-WAN, Secure Access Service Edge (SASE), equipment monitoring, and more. It also provides out-of-band (OOB) management and built-in cellular failover to improve network availability and resilience. Read this case study to learn more.

2. Remotely managing and securing fully automated Smart buildings

Smart buildings use IoT sensors to monitor and control building functions such as HVAC, lighting, power, and security. Property management companies and facilities departments use data analysis software to automatically determine optimal conditions, respond to issues, and alert technicians when emergencies occur. Edge computing allows these automated processes to respond to changing conditions in real-time, reducing the need for on-site personnel and improving operational efficiency.

Best practice: Keep the management interfaces for automated building management systems isolated from the production environment to reduce the risk of compromise or ransomware infection. Use edge computing platforms with Gen 3 out-of-band (OOB) management for control plane/data plane separation to improve resilience and ensure continuous remote access for troubleshooting and recovery. 

3. Analyzing patient health data generated by mobile devices in the healthcare industry

Healthcare organizations use data analysis software, including AI and machine learning, to analyze patient health data generated by insulin pumps, pacemakers, imaging devices, and other IoT medical technology. Keeping that data secure is critical for regulatory compliance, so it must be funneled through a firewall on its way to cloud-based or data center applications, increasing latency and preventing real-time response to potentially life-threatening health issues. Edge computing for healthcare moves patient monitoring and data analysis applications to the same local network (or even the same onboard chip) as the sensors generating most of the data, reducing security risks and latency. Some edge computing applications for healthcare can operate without a network connection most of the time, using built-in cellular interfaces and ATT FirstNet connections to send emergency alerts as needed without exposing any private patient data.

Best practice: Protect patient privacy by deploying healthcare edge computing solutions like Nodegrid with strong hardware roots-of-trust, Zero Trust Edge integrations, and control plane/data plane separation. Nodegrid secures management interfaces with the Trusted Platform Module 2.0 (TPM 2.0), multi-factor authentication (MFA), secure boot, built-in firewall intrusion prevention, and more.

4. Reducing latency for live streaming events and online gaming

Streaming live content requires low-latency processing for every user regardless of their geographic location, which is hard to deliver from a few large, strategically placed data centers. Edge computing decentralizes computing resources, using relatively small deployments in many different locations to bring services closer to audience members and gamers. Edge computing reduces latency for streaming sports games, concerts, and other live events, as well as online multiplayer games where real-time responses are critical to the customer experience.

Best practice: Use all-in-one, vendor-neutral devices like the Nodegrid Gate SR to combine SD-WAN, OOB management, edge security, service delivery, and more. Nodegrid services routers reduce the tech stack at each edge computing site, allowing companies to scale out as needed while minimizing hardware overhead.

5. Improving performance and business outcomes for artificial intelligence/machine learning

Artificial intelligence and machine learning applications provide enhanced data analysis capabilities for essentially any use case, but they must ingest vast amounts of data to do so. Securely transmitting and storing edge and IoT data and preparing it for ingestion in data lakes or data warehouses located in the cloud or data center takes significant time and effort, which may prevent companies from getting the most out of their AI investment. Edge computing for AI/ML eliminates transmission and storage concerns by processing data directly from the sources. Edge computing lets companies leverage their edge data for AI/ML much faster, enabling near-real-time insights, improving application performance, and providing accelerated business value from AI investments.

Best practice: Use a vendor-neutral OOB management platform like Nodegrid to remotely monitor and orchestrate edge AI/ML deployments. Nodegrid OOB ensures 24/7 remote management access to AI infrastructure even during network outages. It also supports third-party automation for mixed-vendor devices to help streamline edge operations. 

6. Enhancing remote surveillance capabilities at banks and ATMs

Constantly monitoring video surveillance feeds from banks and ATMs is very tedious for people, but machines excel at it. AI-powered video surveillance systems use advanced machine-learning algorithms to analyze video feeds and detect suspicious activity with far greater vigilance and accuracy than human security teams. With edge computing, these solutions can analyze surveillance data in real-time, so they could potentially catch a crime as it’s occurring. Edge computing also keeps surveillance data on-site, reducing bandwidth costs, network latency, and the risk of interception.

Best practice: Isolate the management interfaces for all surveillance systems using a Gen 3 OOB solution like Nodegrid to keep malicious actors from hijacking the security feeds. OOB control plane/data plane separation also makes it easier to establish a secure environment for regulated financial data, simplifying PCI DSS 4.0 and DORA compliance.

7. Extending data analysis to agriculture sites with limited Internet access

The agricultural sector uses IoT technology to monitor growing conditions, equipment performance, crop yield, and much more. Many of these devices use cellular connections to transmit data to the cloud for analysis which, as we’ve already discussed ad nauseam, introduces latency, increases bandwidth costs, and creates security risks. Edge computing moves this data processing on-site to reduce delays in critical applications like livestock monitoring and irrigation control. It also allows farms to process data on a local network, reducing their reliance on cellular networks that aren’t always reliable in remote and rural areas.

Best practice: Deploy all-in-one edge gateway routers with environmental sensors, like the Nodegrid Mini SR, to monitor operating conditions where your critical infrastructure is deployed. Nodegrid’s environmental sensors alert remote teams when the temperature, humidity, or airflow falls outside of established baselines to prevent equipment failure. 

Edge computing for any use case

The potential uses for edge computing are nearly limitless. A shift toward distributed, real-time data analysis allows companies in any industry to get faster insights, reduce inefficiencies, and see more value from AI initiatives.

Both edge computing and cloud computing involve moving computational resources – such as CPUs (central processing units), GPUs (graphics processing units), RAM (random access memory), and data storage – out of the centralized, on-premises data center. As such, both represent massive shifts in enterprise network designs and how companies deploy, manage, secure, and use computing resources. Edge and cloud computing also create new opportunities for data processing, which is sorely needed as companies generate more data than ever before, thanks in no small part to an explosion in Internet of Things (IoT) and artificial intelligence (AI) adoption. This year, IoT devices alone are predicted to generate 80 zettabytes of data, much of it decentralized around the edges of the network. AI, machine learning, and other data analytics applications, meanwhile, require vast quantities of data (and highly scalable infrastructure) to provide accurate insights. This guide compares edge computing vs cloud computing to help organizations choose the right deployment model for their use case.

Defining edge computing vs cloud computing

Edge computing involves deploying computing capabilities to the network’s edges to enable on-site data processing for Internet of Things (IoT) sensors, operational technology (OT), automated infrastructure, and other edge devices and services. Edge computing deployments are highly distributed across remote sites far from the network core, such as oil & gas rigs, automated manufacturing plants, and shipping warehouses. Ideally, organizations use a centralized (usually cloud-based) orchestrator to oversee and conduct operations across the distributed edge computing architecture.

Diagram showing an example edge computing architecture controlled by a cloud-based edge orchestrator.

Reducing the number of network hops between edge devices and the applications that process and use edge data enables real-time data processing, reduces MPLS bandwidth costs, improves performance, and keeps private data within the security micro-perimeter. Cloud computing involves using remote computing resources over the Internet to run applications, process and store data, and more. Cloud service providers manage the physical infrastructure and allow companies to easily scale their virtual computing resources with the click of a button, significantly reducing operational costs and complexity over on-premises and edge computing deployments.

Examples of edge computing vs cloud computing

Edge computing works best for workloads requiring real-time data processing using fairly lightweight applications, especially in locations with inconsistent or unreliable Internet access or where privacy/compliance is a major concern. Example edge computing use cases include:

Cloud computing is well-suited to workloads requiring extensive computational resources that can scale on-demand, but that aren’t time-sensitive. Example use cases include:

The advantages of edge computing over cloud computing

Using cloud-based applications to process edge device data involves transmitting that data from the network’s edges to the cloud provider’s data center, and vice versa. Transmitting data over the open Internet is too risky, so most organizations route the traffic through a security appliance such as a firewall to encrypt and protect the data. Often these security solutions are off-site, in the company’s central data center, or, best-case scenario, a SASE point-of-presence (PoP), adding more network hops between edge devices and the cloud applications that service them.  This process increases bandwidth usage and introduces latency, preventing real-time data processing and negatively affecting performance, which is one of the main reasons why organizations are repatriating workloads from the cloud to on-prem.

Edge computing moves data processing resources closer to the source, eliminating the need to transmit this data over the Internet. This improves performance by reducing (or even removing) network hops and preventing network bottlenecks at the centralized firewall. Edge computing also lets companies use their valuable edge data in real time, enabling faster insights and greater operational efficiencies.

Edge computing mitigates the risk involved in storing and processing sensitive or highly regulated data in a third-party computing environment, giving companies complete control over their data infrastructure. It can also help reduce bandwidth costs by eliminating the need to route edge data through VPNs or MPLS links to apply security controls.

Edge computing advantages:

  • Improves network and application performance
  • Enables real-time data processing and insights
  • Simplifies security and compliance
  • Reduces MPLS bandwidth costs

The disadvantages of edge computing compared to cloud computing

Cloud computing resources are highly scalable, allowing organizations to meet rapidly changing requirements without the hassle of purchasing, installing, and maintaining additional hardware and software licenses. Edge computing still involves physical, on-premises infrastructure, making it far less scalable than the cloud. However, it’s possible to improve edge agility and flexibility by using vendor-neutral platforms to run and manage edge resources. An open platform like Nodegrid allows teams to run multiple edge computing applications from different vendors on the same box, swap out services as business needs evolve, and deploy automation to streamline multi-vendor edge device provisioning from a single orchestrator. A diagram showing how the Nodegrid Mini SR combines edge computing and networking capabilities on a small, affordable, flexible platform.

Organizations often deploy edge computing in less-than-ideal operating environments, such as closets and other cramped spaces that lack the strict HVAC controls that maintain temperature and humidity in cloud data centers. These environments also typically lack the physical security controls that prevent unauthorized individuals from tampering with equipment, such as guarded entryways, security cameras, and biometric locks. The best way to mitigate this disadvantage is with an environmental monitoring system that uses sensors to detect temperature and humidity changes that could cause equipment failures as well as proximity alarms to notify administrators when someone gets too close. It’s also advisable to use hermetically sealed edge computing devices capable of operating in extreme temperatures and with built-in security features making them tamper-proof.

Cloud computing is often more resilient than edge computing because cloud service providers must maintain a certain level of continuous uptime to meet service level agreements (SLAs). Edge computing operations could be disrupted by network equipment failures, ISP outages, ransomware attacks, and other adverse events, so it’s essential to implement resilience measures that keep services running (if in a degraded state) and allow remote teams to fix problems without having to be on site. Edge resilience measures include Gen 3 out-of-band management, control plane/data plane separation (also known as isolated management infrastructure or IMI), and isolated recovery environments (IRE).

Edge computing disadvantages:

  • Less scalable than cloud infrastructure
  • Lack of environmental and security controls
  • Requires additional resilience measures

Edge-native applications vs cloud-native applications

Edge-native applications and cloud-native applications are similar in that they use containers and microservices architectures, as well as CI/CD (continuous integration/continuous delivery) and other DevOps principles.

Cloud-native applications leverage centralized, scalable resources to perform deep analysis of long-lived data in long-term hot storage environments. Edge-native applications are built to leverage limited resources distributed around the network’s edges to perform real-time analysis of ephemeral data that’s constantly moving. Typically, edge-native applications are highly contextualized for a specific use case, whereas cloud-native applications offer broader, standardized capabilities. Another defining characteristic of edge-native applications is the ability to operate independently when needed while still integrating seamlessly with the cloud, upstream resources, remote management, and centralized orchestration.

Choosing edge computing vs cloud computing

Both edge computing and cloud computing have unique advantages and disadvantages that make them well-suited for different workloads and use cases. Factors like increasing data privacy regulations, newsworthy cloud provider outages, greater reliance on human-free IoT and OT deployments, and an overall trend toward decentralizing business operations are pushing organizations to adopt edge computing. However, most companies still rely heavily on cloud resources and will continue to do so, making it crucial to ensure seamless interoperability between the edge and the cloud.

The best way to ensure integration is by using vendor-neutral platforms. For example, Nodegrid integrated services routers like the Gate SR provide multi-vendor out-of-band serial console management for edge infrastructure and devices, using an embedded Jetson Nano card to support edge computing and AI workloads. The ZPE Cloud management platform unifies orchestration for the entire Nodegrid-connected architecture, delivering 360-degree control over complex and highly distributed networks. Plus, Nodegrid easily integrates – or even directly hosts – other vendors’ solutions for edge data processing, IT automation, SASE, and more, making edge operations more cost-effective. Nodegrid also provides the complete control plane/data plane separation needed to ensure edge resilience.

Edge-native applications

Edge-native applications are built from the ground up to harness edge computing’s unique capabilities while mitigating the limitations. They leverage some cloud-native principles, such as containers, microservices, and CI/CD (continuous integration/continuous delivery), with several key differences.

Edge-Native vs. Cloud-Native Applications

Edge-Native Cloud-Native
Topology Distributed Centralized
Compute Real-time processing with limited resources Deep processing with scalable resources
Data Constantly changing and moving Long-lived and at rest in a centralized location
Capabilities Contextualized Standardized
Location Anywhere Cloud data center

Source: Gartner

Edge-native applications integrate seamlessly with the cloud, upstream resources, remote management, and centralized orchestration, but can also operate independently as needed. Crucially, they allow organizations to actually leverage their edge data in real-time, rather than just collecting it for later processing.
