By 2025, says the global research and advisory firm Gartner, companies will generate and process more than 75% of their data outside of traditional centralised data centres — that is, at the “edge” of the cloud.

What is edge computing?

  • It enables data to be analysed, processed, and transferred at the edge of a network. 
  • The idea is to analyse data locally, closer to where it is stored, in real-time without latency, rather than send it far away to a centralised data centre.


Difference between edge computing and cloud computing

  • The basic difference between edge computing and cloud computing lies in where the data processing takes place.
  • Currently existing Internet of Things (IoT) systems perform all of their computations in the cloud using data centres. 
  • On the other hand,Edge computing essentially manages the massive amounts of data generated by IoT devices by storing and processing data locally. 
  • The data doesn’t need to be sent over a network as soon as it processed; only important data is sent.
  • An edge computing network reduces the amount of data that travels over the network.
