Common code approach: from rich libraries to rich environment

We run over 800 microservices in our on-premise and public clouds. They are developed by hundreds of engineers in various technologies: from the most popular Java and Kotlin, through Scala, Clojure, Python, NodeJS, Golang, to less mainstream like Elixir or Swift. All these applications need to handle common technical concerns: logging, monitoring, service discovery, tracing, internationalization, security and more. How to provide common solutions to these requirements in such a heterogeneous setup? In this post I’m going to explain how we originally solved this problem with common libraries and how we are currently changing our runtime environment to make things even easier.
