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 | VictoriaMetrics, Prometheus | Nagios, Centreon, 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
- Virtualization
- Storage
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
