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.
📝 Feel free to add more resources by sumitting pull requests
- The following path is opinionated. You can find alternative paths in the next section.
- Remember, DevOps is more a culture rather than a list of tools or platforms. The reason you learn concepts and tools is to be comfortable enough to practice and apply that culture
- Learn what DevOps is all about
Let's start with the must
| Topic | What to learn | Alternatives | Description |
|---|---|---|---|
| Version Control | Git | None | Version Control is used everywhere and Git is the leading version control technology |
| Programming | At least one programming language | Anyone who practice DevOps should know programming to some extent | |
| Operating System | Linux | Windows | Operating Systems is another must when it comes to DevOps |
| Protocols | DHCP, UDP, TCP, SSH | Not as an alternative, you can simply learn later: NFS, NTP | 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 |
What's next? (Note: the order isn't important)
| 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 | OpenStack | |
| 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 (Elasticsearch and Logstash), Report Portal | Graylog, Splunk | |
| Monitoring | Prometheus and Grafana | Nagios, Datadog |

In general, you should be comfortable with:
- 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
Deep dive into operation system internals. I would say choose Linux but I must admin I'm biased. If you did choose Linux, here is a list of resources that will help you learn Linux
| 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
| Name | Description |
|---|---|
| Periodic table of DevOps tools | Table of DevOps tools per category |
| DevOps tool chest | List of DevOps tools |
| DevOps Bookmarks | NSIA |
| CNCF Cloud Native Interactive Landscape | CNCF's recommended path through the cloud native landscape |
| DevOpsBookmarks | To discover tools in the devops landscape. |
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 |
Another great way to learn is to learn from the experience of others. For that, the are some excellent DevOps communities.

| DevOps Bits | Facebook DevOps group. Disclosure: I started it :) |
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.
