The word “isolation” gets used loosely. A Docker container is “isolated.” A microVM is “isolated.” A WebAssembly module is “isolated.” But these are fundamentally different things, with different boundaries, different attack surfaces, and different failure modes. I wanted to write down my learnings on what each layer actually provides, because I think the distinctions matter and allow you to make informed decisions for the problems you are looking to solve.
For implementers, backpressure adds complexity without providing guarantees. The machinery to track queue sizes, compute desiredSize, and invoke pull() at the right times must all be implemented correctly. However, since these signals are advisory, all that work doesn't actually prevent the problems backpressure is supposed to solve.
