Elixir-Style Actors in Go :: Random Bits of Wisdom
My foray into Elixir brought forward many more similarities between it and Go, than I originally expected. One of them is how both handle concurrency. With respect to that, creating Elixir-style stateful actors in Go is surprisingly easy. Answering the question, whether one needs them, or can make use of them, I’d leave to the user.

Monitoring and Tracing Your Go Services - GothamGo 2017
“If a Go microservice falls down in the middle of a server farm, does my pager make a sound?†If your service is automatically monitored, then the answer is “yes!â€. But what if your service isn’t monitored yet? Or what if your monitors alert you when the server is offline, but not on subtler problems like latency spikes or CPU load? Fortunately, there’s a quick and easy way to get high-resolution
