DevOps is really common right now, and many of my friends, colleagues, and senior developers are working hard to become DevOps engineers and project themselves as DevOps champions in their organisations.
While I fully recognise the advantages of DevOps, which are clearly relevant to better software creation and deployment, I can testify from my brief understanding that it is not a simple task. In the midst of so many processes and activities, choosing the right direction can be challenging.
As a Java blogger, I get a lot of questions about how to become a DevOps engineer and which tools I can learn. What are the best practises for me to follow? Is it appropriate for a DevOps person to learn Maven and Jenkins? What about Kubernetes and Docker? Is infrastructure automation a DevOps component? Some of the questions that keep coming up to me are whether I should study Cook, Puppet, or Openstack.
I tried my best to answer them with my limited knowledge, but I couldn’t do so in a way that was both cool and reusable, but don’t worry.

The 2021 DevOps RoadMap
Today, I’m going to be sharing with you The 2021 DevOps RoadMap, a great resource that will help you become the DevOps Developer you’ve always want to be.
Earlier this morning, I was casually browsing the internet when I came across Kamranahmedse’s excellent GitHub page, which shows a couple of useful roadmaps for becoming a front-end developer, back-end developer, full-stack web developer, and, last but not least, a DevOps Engineer.
This RoadMap is amazing in every way because it not only describes what a DevOps engineer does, but it also informs you the tools and technologies you’ll need to master in order to cover that area.
Furthermore, it is visually pleasing, with pretty colours (don’t you like yellow and cream with blue lines? ), so you can easily print it out and keep it on your desk for easy reference.
Although this roadmap is helpful in that it instructs you on what to learn, it does not instruct you on how to learn or where to learn. To round out the roadmap, I’ve also included some free and paid online DevOps courses so you can learn and develop the resources or areas you’re interested in.
DevOps RoadMap for Developers 2021
Okay, here’s the DevOps Roadmap for 2021 that I’m referring to:
Let’s take a look at the RoadMap step by step to see how you can learn the requisite skills and right certifications to become a DevOps guru in 2021:
1. Learn a Programming Language
If you didn’t, don’t worry; you can learn your prefered language by taking one of the courses mentioned below, but I strongly encourage you to learn at least one of these three big general-purpose programming languages.
Java is a programming language that is used. The Full Java MasterClass is a fantastic course for learning Java, and it was recently revised for Java 10.
If you want to learn Python, my favourite resource is The Full Python BootCamp, which teaches Python 3, the most popular version of Python.
2. Learn and Understand various OS concepts
This is where the Ops component comes in; historically, it was primarily the duty of support and sysadmins to be knowledgeable about operating systems and hardware; now, with DevOps, developers must now be knowledgeable as well.
As suggested in the roadmap, you should be familiar with Process Management, Threads and Concurrency, Sockets, I/O Management, Virtualization, Memory Storage, and File Systems.
Since many of us work with Linux, I recommend taking the Linux Administration BootCamp course on Udemy to learn more about the operating system.
If you’re searching for more options and don’t mind learning from publicly available tools, check out this list of free Linux courses.
3. Learn to Live in terminal
Develop the ability to use the terminal commands. What did I say this? Its simply because it is crucial for a DevOps engineer to be comfortable with the command line, particularly if he’s working with Linux. It is required to be familiar with a Linux shell such as Bash or Ksh, as well as tools such as find, grep, awk, sed, lsof, and networking commands such as nslookup and netstat.
If you need a refresher online class on these commands and tools, enrol in Pluralsight’s Linux Command Line Interface (CLI) Fundamentals course.
It’s an excellent refresher for both new and seasoned Linux users. To access the course, you’ll need a Pluralsight membership, which costs about $29 per month or $299 a year but is well worth it.
Pluralsight is just like Netflix for developers; it has over six thousand high-quality courses on cutting-edge technology. This will enable you to learn everything and anywhere. I practise much of what I know when travelling and commuting.
If you want more options and want to become a shell scripting master, check out my list of the best courses to learn shell scripting.
4. Networking and Security
Remember the good old days of isolation; in today’s world, everything is linked to everything else, necessitating the importance of networking and security.
Basic networking and security concepts such as DNS, OSI Model, HTTP, HTTPS, FTP, SSL, TLS, and others are needed to become a good DevOps engineer.
TCP/IP and Networking Fundamentals for IT Pros is a good place to start if you want to refresh your memory on this subject. Pluralsight course by Ed Liberman.
If you want more options, try these Udemy courses: The Complete Networking Fundamentals is a good course for networking, and The Complete Cyber Security Course: Network Security! is a good course for security.
What is it and how do you set it up?
You should know what is set up in your machine and how to set it up as a DevOps champion, and you should be able to think about automating it.
A DevOps engineer should be able to set up a Web server such as IIS, Apache, or Tomcat in general.
He should also be familiar with Caching Servers, Load Balancers, Reverse Proxy Servers, and Firewalls, among other items. If you’re new to the web development community, Colt Steele’s Web Developer Bootcamp is a great place to start.
6. Learn Infrastructure as code
This is possibly the most important aspect for a DevOps engineer to consider, and it is also a very broad subject. You should be familiar with containers such as Docker and Kubernetes, configuration management software such as Ansible, Chef, Salt, and Puppet, and infrastructure provisioning tools such as Terraform and Cloud creation as a DevOps engineer. Here are some of the courses I suggest for learning these methods.
The Docker Mastery: The Full Toolset From a Docker Captain course on Udemy is the best place to start if you want to learn Docker. It covers all of the resources that a DevOps engineer would need in detail.
I recommend taking the Learn DevOps: The Complete Kubernetes course if you want to learn Kubernetes. You’ll learn how to create, deploy, and manage Kubernetes in this course.
And, if you want to learn Chef, Chef Fundamentals: A Recipe for Automating Infrastructure on Udemy is the best place to start. Possibly the best course for learning to be a chef right now.
If you want to learn more about Docker, check out this list of 10 important DevOps Engineer courses.
7. Learn some Continuous Integration and Delivery (CI/CD) tools
Setting up a pipeline for continuous integration and distribution is another crucial activity for DevOps gurus and champions. Jenkins, TeamCity, Drone, and other CI/CD resources are only a few examples.
But, since Jenkins is the most commonly used and potentially the most mature CI/CD tool on the market, I highly encourage you to learn it. If you’re new to Jenkins, this is the best place to start.
If you want to learn Jenkins, the classic Learn DevOps: CI/CD with Jenkins using Pipelines and Docker on Udemy is the best place to start. It’s clearly the best course, and it’s where I learned the bulk of my Jenkins skills.
If you’re searching for more options and don’t mind learning from free tools, check out my list of 6 free Jenkins and Maven courses for Java developers.
8. Learn to monitor software and infrastructure
Monitoring, in addition to setup and implementation, is an essential part of DevOps, which is why a DevOps engineer can learn about infrastructure and application monitoring.
Nagios, Icing, Datadog, Zabbix, Monit, AppDynamic, New Relic, and other resources exist in this space.
You can pick any of them, such as AppDynamic and Nagios, based on which one is currently in use at your business.
9. Learn about Cloud Provides
Cloud is the next big thing, and you’ll have to migrate your application to the cloud sooner or later. As a result, a DevOps engineer should at least be familiar with some of the most common Cloud Providers and their fundamentals.
Although AWS is obviously the pioneer in the cloud, it is not alone; Google Cloud and Azure are catching up, and we also have Heroku, Cloud Foundry, and Digital Ocean to consider.
However, to begin, I highly recommend enrolling in Udemy’s classic AWS Serverless APIs & Apps — A Full Introduction course, which is simply the best.
If you’re searching for more options and don’t mind learning from free tools, check out my list of free AWS courses for developers and DevOps professionals.

In conclusion, I will say a big thank you for taking the time to read this far. You may be worried that there is too much to learn and too many classes to enrol in, but don’t be.
There’s a fair chance you already know much of this. And there are a lot of useful free resources you can use, which I’ve linked to here and there along with the best resources, which aren’t free but are well worth your money.
I am a big fan of Udemy courses because they are inexpensive and offer a lot of value for a small price, but you can choose any course you want.
At the end of the day, you should have ample information and experience in the areas covered.
Best wishes on your DevOps journey! It won’t be easy, but following this roadmap and guide will get you one step closer to becoming the DevOps engineer you’ve always wanted to be.
