What is Edge Computing?

Edge Computing has become a buzzword in the world of technology, especially in the field of IoT (Internet of Things). As the amount of data generated by IoT devices increases, traditional cloud computing infrastructure faces significant challenges. Either in terms of latency and bandwidth, or in terms of security. In response to these challenges, Edge Computing has emerged as a new paradigm for computing. Wherein data processing is closer to its source.

If you are wondering what Edge computing is, this blog post is for you. This piece of writing will dive deeper into this new tech and explore its benefits, use cases, and future potential.

So, let’s get straight to it.

Understanding Edge Computing

Edge Computing is a distributed computing paradigm where computation is performed closer to the data source than in a centralized cloud. It involves processing data at the edge of the network, where devices generate the data, rather than sending it to a remote server for processing.

It can be implemented using edge devices such as IoT gateways, routers, or edge servers that can process data in real-time and provide real-time feedback to the end user. This approach reduces the amount of data that needs to be transferred to a remote data center or cloud, which in turn reduces latency, network bandwidth, and costs.

What does Edge Computing offer?

It offers several advantages over traditional cloud computing. The following are some benefits:

Reduced latency

With Edge Computing, data is processed closer to its source, reducing the time it takes to transfer data back and forth between the device and the cloud. The result is a faster response time, which is critical for applications that require real-time processing, such as autonomous vehicles or industrial automation.

Improved security

Since data is processed locally, it is less vulnerable to cyber threats that may occur during data transfer to a remote server or cloud. This reduces the risk of data breaches and ensures data privacy.

Increased Bandwidth

It also reduces the amount of data that needs to be transferred to a remote data center or cloud, which reduces the amount of bandwidth required. This is especially useful in areas with limited network bandwidth or when working with large amounts of data.


It can be cheaper than traditional cloud computing because it downsizes the amount of data that needs to be transferred and processed in the cloud, reducing the cost of cloud computing.

Edge Computing Applications

It has a number of use cases in various industries. Here are some of the industries that are exploiting the optimum benefits of Edge computing.

Industrial IoT: Edge Computing is widely practiced in the Industrial Internet of Things sector, where it is used to optimize manufacturing processes, improve supply chain management and monitor the health of equipment in real-time.

Smart Cities: It is also used in Smart Cities to monitor traffic, control street lighting, and control waste disposal systems.

Healthcare: This new technology has high prospects in the healthcare industry. It allows patient’s monitoring in real-time, process medical imaging. Therefore, improving the accuracy of diagnoses.

Autonomous Vehicles: Edge Computing is used in autonomous vehicles to process sensor data in real time, allowing vehicles to make quick decisions and respond to changing conditions.


Edge computing vs Cloud computing

Architecture and location

Edge computing brings computing resources closer to the point of data generation. On the contrary, cloud computing relies on centralized servers located at a distance from the end-user. Edge computing devices analyze data locally, reducing the amount of data that needs to be sent over the network. Thus, enabling faster response times. Cloud computing is ideal for businesses that need to scale quickly and efficiently without worrying about the cost and maintenance of their own IT infrastructure.

Data processing and analytics

It is particularly useful for applications that require low latency and real-time data processing. For instance, autonomous vehicles, smart cities, and healthcare monitoring devices. The devices used in edge computing can analyze data locally, thereby reducing the amount of data that needs to be sent over the network and enabling faster response times. Cloud computing, on the other hand, is ideal for applications that require large-scale data processing. For example big data analytics and machine learning.

Security and privacy

Edge computing offers enhanced security and privacy. It allows for local data processing, thereby, reducing the risk of data breaches or cyber-attacks. In contrast, cloud computing relies on remote servers for data processing. Which can lead to security concerns if the servers are not properly secured. However, cloud computing providers often have advanced security measures and protocols in place to protect user data.


Cloud computing offers scalability by allowing businesses to access computing resources on-demand over the internet. This means businesses can scale up or down their computing needs based on their requirements, without worrying about the cost and maintenance of their own IT infrastructure. Edge computing may be limited in its scalability as it relies on local resources and hardware limitations.


The Future

Expectations are that it would continue to grow in popularity. Because the more devices connect to the Internet and generate massive amounts of data the more they require real-time processing. In fact, MarketsandMarkets suggests that global Edge Computing market may grow from USD 3.6 billion in 2020 to USD 101 billion by 2027 at a CAGR of almost 18%.

The COVID-19 pandemic also accelerated the adoption of Edge Computing. Hence, highlighting the need for real-time data processing and reduced network latency in remote areas.

Final thoughts

In conclusion, Edge Computing is a paradigm shift in computing that offers significant advantages over traditional computing. With numerous use cases across industries and expected growth, Edge Computing has the potential to modernize the way we process and analyze data. As more and more devices connect to the Internet, the demand for real-time data processing and analytics will continue to grow. Thereby making it a critical technology for the future of IoT.
