DevOps

DevOps Roadmap

• The following path is opinionated. You can find alternative paths in the alternative roadmaps section
• Do NOT attempt to learn everything, especially if you are a complete beginner (the burnout will make you regret you ever heard the word DevOps)
• Learn enough to say "I know what is DevOps and I understand how to practice it". You can learn everything else by demand or when you feel ready

The must list

The second must list :) Seriously though, don't try to master everything in this list and start with something that you are interested in. The order has no meaning in this case.

Alternative Roadmaps

There are other DevOps roadmaps and learning plans out there. If you feel the one above is little bit too much or just want to look at other options, maybe you'll find the following useful

Learn about DevOps

Learn Git

Make sure you are comfortable with the following list once you done learning Git basics

• Commit changes to a project
• Submit pull/merge requests
• Working with branches
• Rebase changes (change order, squash, ...)

Programming

Practicing DevOps without knowing programming is like eating cornflakes with ketchup - it's just doesn't makes sense (yes, my analogies are the worst).
Here is a list of some good sites to practice programming in general:

A better approach might be to actually write some DevOps related scripts or projects. Start simple. Here are some ideas:

• Write a script that gets a number of instances and a name of a platform (AWS, local, Azure, ...) as parameters and provisions those instances on the chosen platform
• Write a script to parse logs and extract some specific information you are interested in
• Write a script that extracts information from some website using web scraping libraries

Operating Systems

Deep dive into operation system internals. Linux should be your first choice. Here is a list of resources that will help you learn Linux.
Also, don't waste a second on picking the right distribution. For learning OS concepts and internals, any distribution would work fine.

Once you are familiar with the commands and feel comfortable enough to keep deep diving, learn some OS concepts:

• Memory Management
• Processes
• Kernel
• Virtualization
• Storage

Linux Master Application

A completely free application for testing your knowledge on Linux

System Design

System Design can be a complex topic. For that reason, I've created a separate repository for you to learn it properly.

Tooling, Apps & Services

Interactive practice and learning sites

Learning by doing proved to be a very effective way to learn new things. If you are at a point where you don't feel comfortable enough to do it by yourself and you look for some guidance, the following sites might assist you

Community

Another great way to learn is to learn from the experience of others. For that, the are some excellent DevOps communities.

Conferences

Books

Read book! Practice is important and the best way to learn practical things but reading about cultures, methods, concepts, ... has its own important role in your path towards mastering DevOps and SRE.
