Traditional data centers may be located at a considerable distance from a device, which can create network latency. This slows the performance of an application and can cause frustration from end users that can't get sufficiently fast responses to their mobile device requests. New distributed computing architectures, such as MEC, can move many data center functions to the edge of the network in order to get closer to the end devices (whether it's a mobile device, robot or IoT sensor). These are known as edge data centers.
According to PwC, 5G is a key trend driving the creation of a "decentralized small cell network of edge data centers to provide low cost, low latency support for high device density" use cases.
