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

Topic	What to learn	Alternatives	Description
Version Control	Git	-	Version Control is used everywhere and Git is the leading version control technology
Programming	At least one programming language	None. Don't settle for learning only shell scripting	Anyone who practice DevOps should know programming to some extent
Operating System	Linux	Other distribution of Linux :D	Operating Systems is another must when it comes to DevOps
Protocols	DHCP, UDP, TCP, HTTP, SSH	Not as an alternative, you can simply learn later: NFS, NTP, FTP	Learn how these protocols work and what they are used for
Applications	Web Server, Load Balancer, Cache, Database		Learn how they work and try out some implementations (e.g. MySQL for databases and httpd for web servers)
System Design	Availability, Reliability, Scalability, Performance	Learn how to design infrastructure and systems

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.

Topic	What to learn	Alternatives
Configuration Management and IaC	Ansible and Terraform	CM: Chef, Puppet and Salt. IaC: Pulumi and CloudFormation
Cloud	Azure, AWS, GCP	-
Containers	Podman and Kubernetes	Docker instead of Podman. Nomad instead of Kubernetes
CI/CD	Jenkins, GitHub Actions	Gitlab CI, Circle CI, Argo CD
Logging and Dashboards	Elastic Stack, Report Portal, Grafana	Graylog, Splunk
Monitoring	VictoriaMetrics, Prometheus	Nagios, Centreon, Datadog

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 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, ...)

Name	Description
Interactive Git Branching Learning	Visual and interactive way to learn Git branching
Learn git concepts, not commands	Article on Git concepts
Codeacademy Learn Git	Not Free

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:

Name	Comments
HackerRank	Practice Coding skills
Exercism	Over 48 languages and 2600 exercises
LeetCode	Practice programming online

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.

Name	Comments
Linux Journey	Written guides + exercises + quiz
Techmint Linux	Written articles/lessons
Linux Survival	Interactive guide

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.

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

Name	Description
Kodekloud Engineer	perform real tasks by working in a fictional organization
QWIKLBAS	AWS, GCP, ... lab practice

Community

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

Name	Comments

Linkedin DevOps	Linkedin DevOps Community
DevOps Bits	Facebook DevOps group. Disclosure: I started it :)

Conferences

Name	Comments
DevOpsDays	DevOps Conferences around the world

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.

Name	Comments
The Phoenix Project	DevOps explained through a story of a fictional company on the brink of a failure

DevOps Tooling

Note: "Provisioning" tools can be used to perform configuration management to some extent. The same applies for configuration management tools, which can be used for pprovisioning.
