Hi, and welcome to Ivan's Weblog!
Here I write about Containers and other Cloud Native stuff, the underlying technologies, and, of course, Programming. This blog is yet another incarnation of the "Learn in Public" idea. However, I strive to keep my articles experiential. Also, as a visual learner, I put a great deal of effort into drawing diagrams, so I hope you'll enjoy it!
Below you can find an opinionated attempt to organize some of my writings. For the full list of posts, check out the Archive.
