The lifeblood of a contemporary business is data, which offers invaluable business insight and supports real-time control over crucial corporate operations.

The quantity of data that can be routinely acquired from sensors and IoT devices working in real-time from remote places and hostile operating environments is enormous, and it is available to organizations today practically anywhere in the world.

What is Edge computing?

A variety of networks and devices that are at or close to the user are referred to as edge computing, an emerging computing paradigm.

Edge is about processing data more quickly and in a larger volume near the point of generation, providing action-driven solutions in real-time.

Compared to conventional models, where processing power is centralized at an on-premise data center, it has some distinctive features.

By locating computing at the edge, businesses may better manage and utilize physical assets and develop fresh, engaging, human experiences.

Self-driving automobiles, autonomous robots, data from smart equipment, and automated retail are a few examples of edge use cases.

Edge may consist of the following elements:

Edge gadgets Every day, we utilize edge computing devices like smart speakers, wearables, and phones, which collect and process data locally while interacting with the real world.

Robots, cars, POS systems, Internet of Things (IoT) devices, and sensors can all be edge devices if they communicate with the cloud and do local computation.

Edge of the network: Edge computing does not require the existence of a separate “edge network” (it could be located on individual edge devices or a router, for example).

There is just another point on the continuum between users and the cloud when a different network is involved, and this is where 5G may be useful.

With low latency and high cellular speed provided by 5G, edge computing will have access to incredibly powerful wireless connectivity, opening up intriguing possibilities for projects like autonomous drones, remote telesurgery, smart city initiatives, and much more.

When putting computation on premises is too expensive and cumbersome but great responsiveness is required, the network edge can be especially helpful (meaning the cloud is too distant).

On-premises infrastructure, which may include servers, routers, containers, hubs, or bridges, is used to manage regional systems and provide connections to the internet.

How is edge computing implemented?

Location is the only factor in edge computing. Data is generated at a client endpoint, such as a user’s computer, in conventional enterprise computing.

Through the corporate LAN, where the data is stored and processed by an enterprise application, the data is transferred across a WAN, such as the internet.

The client endpoint is then given the results of that work. For the majority of common business applications, this client-server computing strategy has been demonstrated time and time again.

Yet, traditional data center infrastructures are having a hard time keeping up with the increase in internet-connected gadgets and the amount of data such devices produce and require.

By 2025, 75% of enterprise-generated data, according to Gartner, will be produced outside of centralized data centers.

The idea of transferring so much data in circumstances that are frequently time- or disruption-sensitive puts a tremendous amount of burden on the global internet, which is already frequently congested and disrupted.

As a result, IT architects have turned their attention from the central data center to the logical edge of the infrastructure, shifting storage and processing resources from the data center to the location where the data is generated.

Simple: If you can’t move the data closer to the data center, move the data center closer to the data.

The idea of edge computing is not new; it is based on long-standing theories of distant computing, such as remote offices and branch offices, which held that placing computing resources close to the desired location rather than relying on a single central site was more dependable and efficient.

Cloud, edge, and fog computing

The ideas of cloud computing and fog computing are strongly related to edge computing.

Despite some similarities, these ideas are distinct from one another and normally shouldn’t be utilized in the same sentence. It’s beneficial to contrast the ideas and recognize how they differ.

Highlighting their shared characteristic is one of the simplest methods to comprehend the differences between edge, cloud, and fog computing:

All three ideas are related to distributed computing and center on how computing and storage resources are physically deployed in relation to the data that is being generated. Where those resources are placed makes a difference.

To decide which model is best for you, compare edge computing, cloud computing, and edge computing.


The placement of computer and storage resources at the site where data is generated is known as edge computing.

In an ideal scenario, these places compute and store close to the data source at the network edge.

For instance, to gather and analyze data generated by sensors inside the wind turbine itself, a tiny container with multiple servers and some storage might be put on top of the device.

Another illustration is the placement of a small amount of computing and storage within a railway station to gather and interpret the vast amounts of sensor data from the rail traffic and track.

The outcomes of any such processing can then be returned to a different data center for manual inspection, archiving, and merging with the outcomes of other data for more extensive analytics.


Large-scale, highly scalable deployment of computer and storage resources to one or more geographically dispersed locations is known as cloud computing (regions).

The cloud is a favored centralized platform for IoT deployments since cloud providers’ offers include a variety of pre-packaged services for IoT operations.

The closest regional cloud facility may still be hundreds of miles from the location where data is collected, and connections rely on the same erratic internet connectivity that supports traditional data centers, despite the fact that cloud computing offers more than enough resources and services to handle complex analytics.

In actuality, cloud computing serves as an alternative to existing data centers, or perhaps as a complement to them.

Centralized computing can be brought much closer to a data source thanks to the cloud, but not at the network edge.

Using edge computing

Data processing is done closer to the data source thanks to edge computing.

Acceptance of edge computing

Just 27% of those surveyed had already used edge computing technology, although 54% think the concept is intriguing.

In order to gather and process data locally, edge computing places storage and servers where the data is. This typically only requires a partial rack of equipment to operate on the remote Network.

The computing equipment is frequently installed in shielded or hardened enclosures to shield it from extremes in temperature, moisture, and other environmental factors.

Just the results of the analysis are sent back to the main data center during processing, which frequently includes normalizing and analyzing the data stream to hunt for business information.

Business intelligence concepts might differ greatly. Examples include retail settings where it may be possible to integrate actual sales data with video monitoring of the showroom floor to identify the most desirable product configuration or consumer demand.

Predictive analytics is another example that can direct equipment maintenance and repair prior to real flaws or failures.

Even other instances frequently include utilities, like the production of electricity or water, in order to preserve the efficiency of the machinery and the standard of the output.

Architecture for edge computing

Using a network of edge devices, edge computing, in contrast to cloud computing, enables data to exist closer to the data sources.

Fog. Nevertheless, neither the cloud nor the edge is the only option for deploying computing and storage.

Even though a cloud data center may be too far away, strict edge computing may not be feasible due to resource constraints, physical dispersion, or distributed deployment.

The idea of “fog computing” can be helpful in this situation. Fog computing often takes a step back and places processing and storage resources “inside,” rather than always “at,” the data.

Fog computing settings can create staggering amounts of sensor or Internet of Things (IoT) data that are spread across enormous physical areas and are just too big to define an edge.

Smart utility grids, smart cities, and smart buildings are a few examples. Think of a “smart city,” where data is utilized to monitor, assess, and improve the city’s public transportation system, municipal services, and utilities, as well as to inform long-term urban planning.

Fog computing can run a number of fog node installations inside the scope of the environment to gather, process, and analyze data because a single-edge deployment simply cannot manage such a load.

Applications and benefits of edge computing

Businesses will be able to reinvent experiences with the help of edge and cloud.

Manufacturing and the Internet of Things are only a small portion of the potential uses for edge computing.

Edge can be used to encourage quick decisions and enhance user experiences by boosting relevance at every touchpoint.

Now, with the support of the broader cloud backbone, edge is assisting in the creation of new insights and experiences.

Among the advantages of edge computing are:

Quick reaction: Transmission of data requires time. In other use scenarios, such as telesurgery or self-driving cars, there isn’t enough time to wait for data to travel back and forth from the cloud.

In these situations, where real-time or highly quick results are required, Edge makes sense.

Large data volume: The cloud is capable of handling extremely high data volumes, but there are considerable transmission costs and physical network capacity constraints to be aware of. Processing the data at the edge may be more advantageous in some circumstances.

Privacy: Users may choose to preserve control of sensitive data locally rather than transmitting it to the cloud (or may be obliged to).

Various use cases fall under the category of “remote” in terms of connectivity, whether they are truly remote (such as an offshore oil drilling platform) or merely remote (involving mobile or transportation-related scenarios using edge).

Cost sensitivity: Processing data entails varying cost profiles across the cloud continuum, which can be improved to reduce overall system costs.

Autonomous operations: Users may require end-to-end processing within the local environment to maintain operations if access to the cloud is not possible or is expected to be intermittent or unstable.

The main benefit of edge computing is obvious: user experience is enhanced as relevance rises. Edge also makes vital data accessible to guide future innovation and new business opportunities.

More sensors provide more data, and the site where the data is created processes the data more, making it faster, more dependable, and safer.

The system produces better forecasts and more pertinent information when knowledge from the cloud is integrated, continuing a cycle of continual development.

The following are other traits of edge use cases:

Edge enables users to digest data quickly, enabling robots and sensors to make split-second decisions and carry out operations in a better, faster, and safer manner.

Intelligent machines and real-time productivity. Everything is being revolutionized by this, including quality control on the manufacturing line and smart signage.

Aiming for the best user experience and lowest cost, digital production and consumption are edge-working for content distribution, for instance, or on an offshore oil well.

Experience with extended reality: From smart health to mixed-reality gaming, these use cases can merge digital twins and optimize rich experiences in healthcare, the workplace, and entertainment.

Privacy and security are prioritized: These use cases increase dependability and safeguard privacy by processing sensitive data at the edge.

Examples include the processing of regulated data and wearable medical technology.

Always-on and untethered: Edge enables processing and decision-making for remote and mission-critical applications, such as POS or autonomous operations, independent of connectivity.

Edge computing illustrations

Let’s look at a few fringe use cases that are presently taking place and will only become better with a wider 5G rollout and other advancements.

Retail: A Shop of Tomorrow concept, a new integrated vision for the near future of retailing, is built around a flexible, customer-centered experience.

Edge technology is a crucial enabler for the human-centered experiences at the core of this paradigm and will soon be a core retail competence.

Frictionless shop checkout is one of the applications of edge. Long lineups are a retailer’s worst nightmare: 86% of customers have walked out of a store because of them, costing the US economy an estimated $37.7 billion in lost sales each year.

Customers can exit the store by a kiosk that appropriately charges their accounts without waiting in line because the edge network in the store processes data from on-site cameras using AI that is taught to recognize inventory items.

Retailers can improve customer service, stop theft, and manage their supply chains and inventories more effectively.

Edge computing opportunities and difficulties

Adoption challenges can occasionally arise for businesses wanting to reap the benefits of edge computing.

Finding the ideal edge strategy is difficult, but it’s crucial to experiment—constantly improving the plan to put your company on the road to success. The issues we encounter most frequently are:

Absence of integrated and common architectures: The appropriate infrastructure (e.g., cloud provider(s), network, and devices) is needed to get the edge up and operating. Enterprises frequently employ numerous, incompatible tech stacks, which must be synchronized for the edge to function at its best.

A dynamic ecology with a range of technological options: There are many potential partners and technological options, therefore important choices must be taken.

The environment is becoming even more complex as a result of ongoing network capabilities innovations like MEC and 5G.

Unrealized business value at the edge: It can be challenging for businesses to comprehend the entire business value that solutions at the edge have the potential to uncover.

Businesses must move past simple use cases that generate rapid returns in order to invest in attractive, practical, and viable edge computing experiences that generate long-term ROI.

Pilot purgatory and innovation fatigue: It can be challenging to industrialize and scale cutting-edge technologies for actual value, and frequently businesses are too rigid to swiftly adapt and grow beyond proof of concept.

Without having the necessary cloud expertise to know what belongs at the edge, why, and when: For businesses that are currently utilizing the cloud, Edge isn’t about retooling. It involves pushing those powers to the limit.

If you already have cloud talent on staff, you can use their expertise to deploy at the edge; setting up the hardware connection is the easy part.

At the edge, specific security challenges exist: Security needs to easily extend from the cloud to any potential edge instances, but it differs greatly from IT security in the IoT and edge domains.

The edge is home to numerous autonomous, time- and safety-sensitive operations. Devices utilized at the edge have a long design life and legacy infrastructure, which security models take into account.

If reboots have an adverse effect on productivity or safety, they may become soon comparably obsolete and rapid patching may be impossible.

Devices may also be situated remotely or in unreliable surroundings, necessitating a combination of physical and cyber security.

Combinations of heterogeneous hardware, software, and networks make it more difficult to put out security patches.
