The DevOps ecosystem has been rapidly growing over the past five years, but I’ve been asked the same question, which is difficult to answer in just a few sentences What is the best way to become a DevOps engineer?
I recently developed Jobs for DevOps, a dedicated job board specifically for the DevOps community. I am using this opportunity to provide the learning roadmap to answer the same question.
1. Begin by educating yourself about The Culture
DevOps is a movement and an idea before it is a job. This is the reason the cultural aspect is crucial.
2. Learn A Programming Language
A successful DevOps engineer is skilled both in development in operations and development.
Python Go, Nodejs, you have many options! It is optional to be able to use the same programming language as your business operates, but programming knowledge is helpful to possess.

3. Learn to Manage Servers
One of the most important duties that a DevOps professional performs is to manage servers. Understanding how servers work is essential; for this, an adequate knowledge of Hardware (CPU and architecture, memory ..) is necessary. Another thing to know is the operating system and specifically Linux. Start by selecting an operating system such as Ubuntu.
If you’re a beginner in Linux, You can test it on your desktop or laptop and begin playing around to get familiar with it.
You can also use DigitalOcean, Amazon Lightsail, or Linode to set up a low-cost server and start learning Linux.
4. Learn Networking and Security Basics
These are competencies for networking and security engineers. Not so! You must know how HTTP, DNS, FTP, and other protocols operate, secure the software you have installed, be aware of security vulnerabilities in the code, and set up an infrastructure system.
5. Learn Scripting
With the ever-growing number of tools that can serve as an alternative to writing the script you want, it is still an essential skill, and you’ll need it in the future. From my experience, Bash is one of the most frequently used scripting languages. Python is also considered to be a powerful scripting language that can be used to run faster and write smaller amounts of code.
6. Learn to Install and Configure Middleware
Apache and Nginx are the most commonly used Middleware in the DevOps industry. Knowing how to set up and configure virtual hosts, reverse proxy servers, domain names, and SSL can help you greatly during your day-to-day tasks.
7. Discover How to deploy software
Once you have learned how to configure and deploy Nginx, it is essential to deploy applications to an actual server.
Create a Hello World application by using Python, Nodejs, and PHP. Implement these three programs. You can utilize Nginx as a reverse proxy for any of the three.
8. Learn GIT
GIT is among the most popular versioning systems used within IT. GIT is one of the versioning systems used in the IT industry. It’s not necessary to be a GIT expert, but its technology will guide you through your DevOps encounters.
GIT fundamentals are defined in the official GIT documentation.
9. Learn How To Develop Software
The process of building is before the running. Software development is typically about making a software release that can be run on the production server. A DevOps professional should be aware of this vital aspect of the software development lifecycle.
Create an application using your preferred language, look at the various methods to install the dependencies, and develop your code.
DevOps Post Graduate Program, as well as DevOps Engineering Training, can allow engineers to act as an inner commando team, helping solve a variety of issues, which, though maybe not appealing or obvious to the general public, are crucial to the success of a business.
10. Learn How to automate Your Software Factory

12. Learn Infrastructure As Code
IaC is essential to automatize your infrastructure and provide your environment with simple scripts and other tools. DevOps is about decreasing the time to market while maintaining high-quality software; IaC can assist you in this.
Select a cloud service (AWS, GCP ..etc.), and you’ll be able to access many free online tools to get started with your infrastructure. It is also possible to learn to use “cloud managers” techniques, and some CM tools such as Saltstack can help set up infrastructure on AWS or GCP in case you’re looking for more, go for the latest technologies like Terraform.
13. Understand to Control Software & Infrastructure
The software that is in production, as well as the infrastructure hosting it needs to be closely monitored. Monitoring and alerting are two of the essential capabilities you must master.
Zabbix, Icinga, Sensu Prometheus. You can study numerous tools, but you must compare these tools and choose one that best meets your needs. You could also learn how to set up and utilize the ELK stack.
14. Learn About Containers & Orchestration
Containers such as Docker are becoming a mandatory ability! You must have capabilities in building, creating and deploying containers and managing them for development or production environment.
15. Learn How to deploy and manage Serverless applications
Serverless is among the most popular technologies of 2017, and it is expected that sooner it will be a necessity in numerous job descriptions.
AWS Lambda, Azure Functions, Google Cloud Functions, IBM OpenWhisk or Auth0 WebTask, you can make the option of learning one of them.
