Edge computing

Edge computing is a distributed computing model that brings computation and data storage closer to the sources of data, so that a user is likely to be physically closer to a server than if all servers were in one place. This often makes applications faster.^[1] More broadly, it refers to any design that pushes computation physically closer to a user, so as to reduce the latency compared to when an application runs on a single data centre.^[2]

The term began being used in the 1990s to describe content delivery networks—these were used to deliver website and video content from servers located near users.^[3] In the early 2000s, these systems expanded their scope to hosting other applications,^[4] leading to early edge computing services.^[5] These services could do things like find dealers, manage shopping carts, gather real-time data, and place ads.

The Internet of Things (IoT), where devices are connected to the internet, is often linked with edge computing. However, it's important to understand that edge computing and IoT are not the same thing.^[6]
