Wanna learn some Containers and Kubernetes internals? Struggle to understand what this Cloud Native buzz is about? On a mission to master the server-side craft? Then you are at the right place!
This blog focuses on the fundamentals behind such overhyped technology like Docker, Kubernetes, or Service Mesh. I keep the articles experiential and put a great deal of effort into the explanatory drawing.
Below is an opinionated attempt to organize some of my writings. For the full list, check out the Archive.
