Technologies are changing very rapidly and today there is a lot of discussion about Edge Computing Vs Cloud Computing. Both technologies have their advantages as well as their principles and architecture.
In this article, we will learn in detail about edge computing and cloud computing and will also understand the difference between these two. We will understand the different uses of these two technologies in simple words. So let’s get started.
Defining Edge Computing and Cloud Computing
Edge Computing
Edge Computing is a technical mechanism in which data processing and storage is done close to the source of the data. This means that when we have a lot of data, such as from smartphones, sensors, or Internet of Things (IoT) devices, it is stored where the data is generated, rather than sending it to a different server.
Edge computing eliminates the need for long wait times for servers to process data, thereby reducing response times.
Also, processing data locally instead of sending it over the network saves bandwidth and hence it saves the network load.
Cloud Computing
Cloud Computing is an ongoing technology which makes computer resources and services available through the Internet. In Cloud Computing, the data and software are not stored on the user’s computer or server instead it is available on a remote server, which requires an internet connection to access.
The major advantage of Cloud Computing is on-demand availability. This simply means that Cloud Computing provides the resources such as servers, storage, and software when users need them. Only when the user uses it, the user will have to pay a charge for it. This facility is called Pay-As-You-Go.

Conclusion
Hope you now understand the Edge Computing Vs Cloud Computing concept. So, Edge computing is a subset of Cloud Computing. At one side the Cloud computing is all about hosting applications in a core data center while Edge Computing is hosting applications closer to end users. It can be either in a smaller edge data center or on the customer premises. Even in this tight competition, the cloud computing will remain be a crucial part of IT infrastructure.
