Want to 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 of such overhyped technologies as Containers, Docker, or Kubernetes. As someone going through the same learning journey, I try to keep articles experiential and put a great deal of effort into the explanatory drawings. Hope you'll find the materials helpful!
Below is an opinionated attempt to organize some of my writings. For the full list, check out the Archive.
