DevOps is really hot at the moment and most of my friends, colleagues, and senior developers I know are working hard to become DevOps engineers and project themselves as DevOps champions in their organization.
While I truly acknowledge the benefits of DevOps, which is directly linked to improved software development and deployment, from my limited experience I can say that it's not an easy job.
It's very difficult to choose the right path in the middle of so many tools and practices.
Being a Java blogger, many of my readers often ask me questions like how to become a DevOps engineer, which tools should I learn? and which practices should I follow. does learning Maven and Jenkins must for a DevOps guy?
How about Docker and Kubernetes? Is the infrastructure automation part of DevOps? should I learn Chef, Puppet, or Ansible are just some of those questions which keep coming to me.
I have tried hard to answer those with my minimal experience but I couldn't jot them down in a manner that is simply awesome and reusable, but, not to worry.
Today I am going to share with you an awesome resource that will help you to become the DevOps Engineer you always wanted to be, the 2025 DevOps Engineer RoadMap.
I was casually surfing through the internet yesterday when I came across thisexcellent GitHub page by Kamranahmedse, which shows a couple of useful roadmaps to become a front-end developer, back-end developer, a full-stack web developer, and last but not the least, the DevOps Engineer.
This RoadMap is awesome in any sense as it does not only highlight what is the role of a DevOps engineer but also tells which tools and technologies you need to learn to cover that area.
On top of that, it's visually appealing with nice colors(don't you like yellow and cream with blue lines?), so you can just take a printout and stick in your desk for easier reference.
Though the roadmap is good in the sense that it tells you what to learn but it doesn't tell you how to learn and where to learn.
In order to complete the roadmap, I have shared some useful online courses, both free and paid, so that you can learn and improve the tools or areas you want.
Btw, I may receive compensation if you buy a course or books I suggest on my post, depending upon if it's free or paid.
The 2025 DevOps Engineer RoadMap
Anyway, here is the 2025 DevOps RoadMap I am talking about:

Now, let's go through the RoadMap step by step and find out how you can learn the essential skills required to become a DevOps guru in 2025:
1. Learn a Programming Language
Obviously and I assume you guys know one of the three main programming language i.e. Java, Python, or JavaScript.
If you didn't, don't worry you can take a look at the below courses to learn your choice of language, though I strongly suggest you learn at least one of these three major general-purpose programming languages.
1.1 Java
If you want to learn Java then The Complete Java MasterClass is a great course, which is also recently updated for Java 17.
1.2 Python
If you want to learn Python, then The Complete Python BootCamp is my favorite resource, which will teach you Python 3, the most popular version of Python.
1.3 JavaScript
And, if you want to learn JavaScript then you should not look beyond Mosh Hamdani's JavaScript Basics for Beginners course on Udemy.
If you need more choices and don't mind learning from free resources then you can always take a look at my list of free Java, Python, and JavaScriptcourses.
2. Understand different OS concepts
This is where the Ops part comes in, earlier it was solely supported by guys and sysadmin people who were responsible for knowing about OS and hardware, but with DevOps, now developer also needs to know them.
You at least need to know about Process Management, Threads and Concurrency, Sockets, I/O Management, Virtualization, Memory storage and File systems as suggested in the roadmap.
Since most of us work in Linux, I suggest you go through the Linux Administration BootCamp course on Udemy to learn and understand Linux OS better.
If you need more choices and you don't mind learning from freely available resources then you can also take a look at this list of free Linux courses.
3. Learn to Live in terminal
For a DevOps guy, it's important to have a good command in command line, particularly if he is working in Linux. Knowing some Linux shell like Bash, or Ksh and tools like find, grep, awk, sed, lsof, and networking commands likenslookup and netstat is mandatory.
If you feel you need to refresh these commands and tools then you should join the Linux Command Line Interface (CLI) Fundamentals course on Pluralsight.
It's a good refresher for both beginner and experienced Linux users. You will need a Pluralsight membership to access the course which cost around $29 per month or $299 per year but it's totally worth it.
Pluralsight is like developer's Netflix, it has more than 6000 high-quality courses on latest technology which means you can learn anything and anywhere.
I mostly learn while traveling and commuting.
Btw, If you need more choices and want to become master on shell scripting, you can also take a look at my list of best courses to learn shell scripting.
4. Networking and Security
Gone are the days of isolation, in today's world, everything is connected to everything which makes networking and security very important.
In order to become a good DevOps engineer, you must know about basic networking and security concepts like DNS, OSI Model, HTTP, HTTPS, FTP, SSL, TLS etc.
In order to refresh this concept, you can take a look at TCP/IP and Networking Fundamentals for IT Pros By Ed Liberman course on Pluralsight.
If you need more choices, you can also check out these Udemy courses like for Networking, The Complete Networking Fundamentals is a nice course and for Security, you can also check The Complete Cyber Security Course: Network Security!.
5. What is and how to setup
As a DevOps champion, you should know what is set up in your machine and how you can set that up, only that you can think about automating it.
In general, a DevOps engineer should know how to set up a Web Server like IIS, Apache, and Tomcat.
He should also know about Caching Server, Load balancer, Reverse Proxy, and Firewall etc. If you are new into web development space, I suggest you to also check out The Web Developer Bootcamp by Colt Steele
6. Learn Infrastructure as code
This is probably the most important thing for a DevOps engineer and this is a very vast area as well. As a DevOps engineer, you should know about containers like Docker and Kubernetes, Configuration management tools likeAnsible, Chef, Salt, and Puppet, Infrastructure Provisioning like Terraform and Cloud formation. Here are some of my recommended courses to learn these tools.
If you want to learn Docker then the Docker Mastery: The Complete ToolsetFrom a Docker Captain course on Udemy is the best course to start with.
It provides comprehensive coverage of all the tools a DevOps engineer will need.
If you want to learn Kubernetes then I suggest you join the Learn DevOps: The Complete Kubernetes course. This will teach you how to build, deploy, and manage Kubernetes.
And, if you want to learn Chef then there is no better course then Chef Fundamentals: A Recipe for Automating Infrastructure on Udemy. Probably the best course to learn Chef at this moment.
If you need more choices on Docker, you can explore this list of 10 essential courses for DevOps Engineer.
7. Learn some Continuous Integration and Delivery (CI/CD) tools
This is another very important thing for DevOps gurus and champion, i.e. to set up a pipeline for continuous integration and delivery.
There are a lot of tools in the CI/CD area e.g. Jenkins, TeamCity, Drone etc.
But, I strongly recommend learning at least Jenkins, as it's most widely used and probably the most mature CI/CD tool in the market. If you don't know Jenkins then this course is best to start with.
If you want to learn Jenkins, then there is no better course than the classic Learn DevOps: CI/CD with Jenkins using Pipelines and Docker on Udemy.
It's simply the best course and I have also learned most of my Jenkins skill from this course.
Btw, if you need more choices and don't mind learning from free resources then you can also check my list of 6 free Jenkins and Maven courses for Java developers.
8. Learn to monitor software and infrastructure
Apart from setup and deployment, monitoring is another important aspect of DevOps and that's why it's important for a DevOps engineer to learn about Infrastructure and application monitoring.
There are a lot of tools in this space e.g. Nagios, Icing, Datadog, Zabbix, Monit, AppDynanic, New Relic etc.
You can choose some of them depending on which one is used in your company like AppDynamic and Nagios.
9. Learn about Cloud Provides (AWS, Azure, or GCP)
Cloud is the next big thing and sooner or later you have to move your application to the cloud, hence it's important for a DevOps engineer to at least know about some of the popular Cloud Providers and their basics.
While AWS is clearly the leader in the cloud it's not alone, Google Cloud and Azure are slowly catching up and then we have some other players like Heroku, Cloud Foundry, and Digital Ocean.
To start with I strongly suggest to join the classic AWS Server less APIs & Apps --- A Complete Introduction course in Udemy, which is simply the best.
Btw, if you need more choices and don't mind learning from free resources then you can also check my list of free AWS courses for developers and DevOps guys.

Closing Notes
Thanks for reading this article so far. You might be thinking that there is so much stuff to learn, and so many courses to join, but you don't need to worry.
There is a good chance that you may already know most of the stuff, and there are also a lot of useful free resources for DevOps Engineers which you can use, I have also linked them here and there along with best resources, which are certainly not free, but worth of money.
I am a particular fan of Udemy courses as they are very affordable and provide a lot of value in a very small amount, but you are free to choose the course you want.
At the end of the day, you should have enough knowledge and experience about the things mentioned here.
Good luck with your DevOps journey!.
It's certainly not going to be easy, but following this roadmap and guide, you are one step closer to becoming the DevOps engineer, you always wanted to be

Great article @javinpaul . Some really good resources here and you did a great job of laying out how deep DevOps tooling goes. I would add that this is only 1/3 of what 'DevOps' IS. Allow me to elaborate.
1/3 Tooling (as you laid out well very well above)
1/3 Culture: removing silos, shift left, leadership buy-in, failure-acceptance culture, and much more
1/3 Automation and decreasing daily toil. With tools comes management, reduce the management to as low as possible. With tools come data, turn that data into actionable information for humans.
Throwing around 'DevOps' as a marketing term for tools and automation does a disservice to the core concept: bringing value to the organization via product ownership; from developer to end-user. No 'walls' that segment teams away from each other. No more 'not my problem' attitudes. No more 'not my job'.
DevOps is more than tools. That's why you do not see many 'Jr. DevOps Engineers'.
That's true and thanks very much for this valuable comment. I know, it's a job which requires a lot of knowledge and experience, both environment, infra, and tools and that's why only experienced developers are migrating but still it's not the easy job and you need to spend quite a time to know what's going on and how to get most of it.
Good article at a practical lever but yes, DevOps is not about the tools. Some people still think, using Jenkins means they are DevOps engineers. DevOps is a group effort and doesn't belong to an individual or role. Since most of the beginners won't understand the term, they have misunderstood this concept. Even some companies prefer tools over people over processes. Hmmm.
But surely, the people who want to start from the beginning will find this article interesting. I think that's what the intention is if I am not mistaken.
Some? 😂
Agree, process and people are always more important than tools. Couldn't have put this better than your comment, thanks :-)
If someone is developer and turns into DevOps like me. This is the challenge I think I have faced. Not much familiar with system and setups and logging Which we can gradually improved. I have done it. I am still learning and exploring operation and system related tasks.
Learning tools will also require the knowledge I mentioned above. One thing I found easy for Dev turned DevOps is we are comfortable writing automation script. Though I had never written a single line of bash script before I turned out to be a most easiest job.
In the beginning, I had never understood why DevOps is the process not tools but Gradually everyone will understand the hidden treasure.
When I saw the roadmap, I though why showing same thing that is already there on github but down bellow, you have written nice information. Thanks
Thanks @taragurung. Agree, Dev turning into DevOps needs to be strong on Linux and bash scripting and that's what this DevOps RoadMap also highlights it, but it's more a process than tools. No doubt tools are important but having a mindset on automation helps a lot. Thanks for your comment and adding value.
I absolutely enjoyed reading this wonderful article on DevOps. The level of detail and clarity used to explain the concepts was incredible. Your hard work is truly commendable! I eagerly await reading your next article.
If you are interested in automating workflows as "Ops" in the CLI and Slack, I would add the Resume Generator Op as an easy entry point to learning the ropes of DevOps automation: cto.ai/docs/tutorial-build-an-op
