Smart devices are growing in numbers around the world moderately. From air conditioners to vehicles all are connected with the internet and generate bulks of data. Edge computing is here to improve the processing speed across theses devices. Computation is brought to the edge of the network, or near the end devices to increase response time and decrease the bandwidth usage.
What is the global market size of edge computing?
The global market size of edge computing was around $ 3 billion in 2019. The market will see moderate growth due to the demand of using edge computing in IoT devices. The number of IoT devices are expected to increase moderately in the near future.
The other main factor is the global commercialisation of 5G network, which will bring more advancement to the world with fast network speed. The combination of 5G and edge computing will bring new shape to the industries and will help in the development of smart factories, cities and homes.
The global market value of edge computing is expected to rise at 5% in 2020, reaching $ 3.13 billion. The pandemic of COVD-19 and lockdowns around the world has greatly affected the edge computing market.
Some of the players in the edge computing market include Dell, IBM, Nokia, Amazon, Huawei, Hewlett Packard, Cisco, ClearBlade, Hitachi Vantara, and Cloudera.
There are various types of edge computing such as localised data centres, local devices and regional data centres. The local data centre of any company or organisation provides more effective computation than centralised cloud, which has a larger distance. As the local data centre is near to end devices, the response time and chances of congestion in the network are also quite low. It usually consists of 1 to 10 racks servers.
Local devices are the cheapest method to perform computing at end devices, and it is usually suitable for small enterprises. One of the examples to understand the local devices use as edge computing is the saving of security videotape on local DVD rather than directly on the centralised cloud. A regional data centre is the same as the local data centre, but it covers more area and has more computing and storage power than the local data centre. It usually consists of more than ten racks of servers.
