WebAssembly aka WASM is migrating from a portable enclosed browser runtime to process serious backend tasks. What makes it so interesting is the fact that the WASM container is secure, efficient, portable and fast - at least on the paper it looks like the better implementation of containers. However, this abilities make WASM very attractive to be utilized in environments with limit capabilities on security isolation, resources and computing power.

We will look into how to get started with WasmEdge and implement a simple application to talk to. Then we will discover the behavior of WasmEdge, and which use cases we can derive from it. And finally where are the limits and critically question if implementations like WasmEdge are really the future.
