Async is not new in Python but I was not familiar with the concept. I have used it but without fully grasping the idea, and that smells disaster. This article and a whole journey I went through has been sparked by one question. Why you shouldn’t run blocking code on the event loop? The answer is simple as it will block the whole thing. I kinda knew that as everyone says it, so you can’t miss it really. But why is it? How does it work? If you would like to know read on.

Bridge to kubernetes
When you are using kubernetes you have a cluster, and clusters are rarely small. Your gripes may come in different flavours though. The cluster won’t fit on your local box any more. You most probably have people in your team that need the cluster as well. You need the feedback faster than deploying your changes to the cluster. What to do with all those problems?
Run a bridge that will route traffic to your local version of one of the microservices. Easy. You will run your service locally that will interact with a kubernetes cluster without interrupting anyone. Sounds amazing, doesn’t it.
To illustrate this let’s run a sample app in a cluster and then do some “development” and “debugging”. This will not affect the “development” environment for other people that could use it. The code will be isolated and your team will be happy.
