DevOps Resources

devops resources

DevOps resources – Linux, Jenkins, AWS, SRE, Prometheus, Docker, Python, Ansible, Git, Kubernetes, Terraform, OpenStack, SQL, NoSQL, Azure, GCP


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

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

TopicWhat to learnAlternativesDescription
Version ControlGitVersion Control is used everywhere and Git is the leading version control technology
ProgrammingAt least one programming languageNone. Don’t settle for learning only shell scriptingAnyone who practice DevOps should know programming to some extent
Operating SystemLinuxOther distribution of Linux ๐Ÿ˜€Operating Systems is another must when it comes to DevOps
ProtocolsDHCP, UDP, TCP, HTTP, SSHNot as an alternative, you can simply learn later: NFS, NTP, FTPLearn how these protocols work and what they are used for
ApplicationsWeb Server, Load Balancer, Cache, DatabaseLearn how they work and try out some implementations (e.g. MySQL for databases and httpd for web servers)
System DesignAvailability, Reliability, Scalability, PerformanceLearn how to design infrastructure and systems

The second must list ๐Ÿ™‚ 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.

TopicWhat to learnAlternativesDescription
Configuration Management and IaCAnsible and TerraformCM: Chef, Puppet and Salt. IaC: Pulumi and CloudFormation
CloudAzure, AWS, GCP
ContainersPodman and KubernetesDocker instead of Podman. Nomad instead of Kubernetes
CI/CDJenkins, GitHub ActionsGitlab CI, Circle CI, Argo CD
Logging and DashboardsElastic Stack, Report Portal, GrafanaGraylog, Splunk
MonitoringPrometheusNagios, 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, …)

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:

HackerRankPractice Coding skills
ExercismOver 48 languages and 2600 exercises
LeetCodePractice 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.

Linux JourneyWritten guides + exercises + quiz

Linux SurvivalInteractive 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

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

Community

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