So, you want to deploy on the edge?
Application developers often deploy their apps into a single area, generally represented by a handful of AZs in a single region. No matter where their users make requests from, those requests get served by the region where the developers’ apps run. If a user makes a request from Europe, and the apps run in US East, that adds an extra 100-150ms of latency just by round-tripping across the Atlantic. Edge computing tries to solve this problem, by letting app developers deploy their applications across the globe, so that apps serve the user requests closer to the user.
