What Is Edge Computing? (Definition of Edge Computing)

Edge computing refers to processing, analyzing, and storing data closer to where it is generated to enable rapid, near real-time analysis and response. In recent times, some organizations have centralized their operations by storing and computing data in the cloud. However, the needs of new use cases enabled by billions of distributed devices have rendered this approach unsustainable, ranging from improved warehouse and inventory management solutions to vision-enhanced robotic production lines to advanced smart city traffic control systems.

Furthermore, the growing use of edge devices—from the Internet of Things (IoT) devices like smart cameras, mobile point-of-sale kiosks, medical sensors, and industrial PCs to gateways and computing infrastructure—for faster, near real-time actionable insights at the data source is driving exponential growth in the amount of data generated and collected.

It’s estimated that by 2025, 75 percent of data will be created outside of central data centers, where most processing takes place today.

By 2025, it’s expected that 75% of data will be created outside of central data centres, where most processing currently takes place. 1 To take it a step further, about 90% of all data acquired by businesses today will never be used. 2 Edge computing uses high-performance processing, low-latency connection, and secure platforms to reap the benefits of data received from devices.

Benefits of Edge Computing

Shifting some data functions such as storage, processing, and analysis away from the cloud and closer to where data is generated might provide several major advantages:

  • Reduced latency and increased speed. Moving data processing and analysis to the edge improves system response time, allowing for faster transactions and better experiences, which are critical in near-real-time applications such as autonomous car operation.
  • Network traffic control has been improved. The bandwidth and expenses of sending and storing huge amounts of data can be reduced by reducing the amount of data delivered over the network to the cloud.
  • Increased reliability. The amount of data that may be transmitted by a network at one time is restricted. The ability to store and process data at the edge enhances reliability when the cloud connection is broken for locations with poor internet connections.
  • Security has been enhanced. An edge computing system, when properly implemented, can improve data security by limiting data transfer over the internet.

Edge Computing Versus Cloud Computing

Key Differences:

Suitable Companies

Edge Computing is said to be appropriate for processes with high latency. As a result, medium-sized businesses with limited budgets can save money by using edge computing.

Cloud Computing is more suitable for projects and organizations which deal with massive data storage.


In Edge Computing, Several different platforms may be used for programming, all having different runtimes.

In Cloud Computing, Actual programming is better suited in clouds as they are generally made for one target platform and uses one programing language.


Edge Computing requires a robust security plan including advanced authentication methods and proactively tackling attacks.

But Cloud Computing requires less of a robust security plan.

Some Frequently Asked Questions

Q) Edge Computing is an Extension of Which Technology?

Edge is an extension of the cloud and requires a common platform-based approach: Adding new technologies like edge to existing cloud platforms makes it much easier to manage and optimize applications.

Think of edge as an extension of the cloud rather than a replacement, says Seth Robinson, senior director of technology analysis at technology association CompTIA.

Q) What is a Recent Innovation in Edge Computing Enhanced by 5G?

Advanced driver assistance systems (ADAS) have taken on a new role in driverless vehicles thanks to edge computing and 5G. Mercedes, for example, uses edge servers and 5G wireless connection to minimize latency and improve bandwidth for sensors while also ensuring real-time authentication.

Q) How Can Edge Computing be Used to Improve Sustainability?

Edge computing helps to reduce network traffic and data center utilization. The amount of data traveling the network may be considerably reduced with Edge Computing, saving up bandwidth. In the context of its surroundings, data on the edge is likewise much more likely to be relevant and indeed utilized.

Q) Which Factors Have Made Edge Computing Cheaper and Easier?

High latency, data privacy, fast performance, and geographical flexibility are some of the factors covered by edge computing that make it cheaper and easier.
