ℹ️  This repository is about gathering any useful resources and information regarding DevOps and secondly, provide some roadmap for those who want to practice DevOps.
đź“ť Â Feel free to add more resources by submitting pull requests
- DevOps Roadmap
- Alternative Roadmaps
- Learn About DevOps
- Learn Git
- Programming
- Operating Systems
- DevOps Toolchain
- 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 | Prometheus | Nagios, Datadog |

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, ...)

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
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
- Virtulization
A completely free application for testing your knowledge on Linux
System Design can be a complex topic. For that reason, I've created a separate repository for you to learn it properly.

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

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