Hello, my name is Ahmed AbouZaid and this is my "lite" technical blog!

I'm a passionate DevOps engineer, Cloud/Kubernetes specialist, Free/Open source geek, and an author.

DevOps transformation, automation, data, and metrics are my preferred areas. And I like to help both businesses and people to grow.
