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 Description
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

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:

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

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
KataKoda Linux, Docker, ML, Kubernetes, ... environments and scenarios
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.
