With edge computing method, there is no need to transfer all the data between the cloud and the device, ensuring that the performance remains consistent.
Edge computing is a form of computing that is a process in which the computing resources are placed outside of the data centre that the computing supports. With this method, there is no need to transfer all the data between the cloud and the device, ensuring that the performance remains consistent.
Types of edge computing
There are a total of three types of edge computing – Cloud edge computing, Device edge computing, and Compute edge computing.
1. Cloud edge computing
Cloud edge computing mainly refers to data centres that are run by cloud providers like Azure, AWS, etc. The main characteristic of cloud edge computing is that this form of computing is centralised and operates at a large scale. While there are many other advantages of cloud edge computing, there are several disadvantages as well. The main disadvantage of this form of computing is that the availability of infrastructure is quite high. This is because there is no assurance that the network connection will be available at the edge. Also, the internet activity cost from and to the cloud is quite costly.
Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data. This is expected to improve response times and save bandwidth. “A common misconception is that edge and IoT are synonymous.
From a performance standpoint, edge computing is able to deliver much faster response times. That’s because locating key processing functions closer to end users significantly reduces latency. In traditional networking, data is typically collected on the edge and transmitted back to centralized servers for processing.
2. Device edge computing
Also known as nano DC, this form of edge computing comprises more than one microserver. Device edge computing would be limited in terms of processing power and would also have few customisations to it. This form of edge computing can be found in areas and networks that do not require or are associated with data centres. The main disadvantage of device edge computing is that it can only use a limited amount of power. They also have limited capabilities.
3. Compute edge computing
Compute edge computing is a form of computing that is quite modest and can be operated from anywhere with a limited amount of server racks as well. Frequently, these computing devices can be placed near or close to IoT equipment. One benefit of this form of computing is that the network latency at the edges is lower than in the cloud.
