Step by Step Sidecar Pattern Tutorial

Sidecar Pattern is an architecture where two or more processes living in same host can communicate with each other via the loop back (localhost) essentially enabling interprocess communication. One of the most use cases of sidecar pattern is service mesh such as Linkerd and Envoy, where process or a container sits next the application and proxy the request and enables logging, service discovery and so much cool features which makes clients become thin in a microservices architecture.

In this tutorial we will learn how can we use the sidecar pattern to decouple application logic into another process and communicate between two processes using the loopback.

I think application should not send NUM to the sidecar, I must send the message string, Because log-sidecar doesn't care about the logic which makes the log message!
