The whole point of edge computing is to get code closer to the people using it. Instead of sending every request to a server halfway across the world, an application can process work at a nearby location and return a response without making that long round trip. On paper, it sounds almost effortless. In practice, a request can still take longer than expected before the application has done anything useful. That delay is often blamed on the network, but the network isn't always the problem. Depending on the platform and runtime, the application may need to initialize its execution environment, load code, evaluate modules, or wait for an external service before it can respond. These costs can be small individually, yet noticeable when they occur at the beginning of a request. This is where serverless edge computing gets interesting. Moving code closer to the user solves one part of the latency problem. It doesn't automatically solve everything that happens between receiving a req...
