Top 7 Skills Required for DevOps Engineers in 2024 (with Roadmap)

From setting up entire environment infrastructures in the cloud or on-premise to automating processes, the responsibilities of a DevOps engineer are quite vast. This article outlines the seven essential skills you need to become a great DevOps engineer in 2024. This should help you understand the key role of DevOps and point you to different technologies that you need to focus on learning.

The Path

Being a DevOps engineer requires proficiency in many different tools. Let’s review each of the seven major categories in which each DevOps engineer should be skilled.

1. Linux Operating System

First on our list is the Linux Operating System. The majority of the servers, either in the cloud or bare metal, are powered by Linux distributions. The reason is simple. It's free, has a small footprint, has a gigantic community, and its stability and security are far ahead of any other operating system available today. Since DevOps commonly deals with handling different kinds of servers, chances are the majority of them would be running in Linux.

Here are the main topics that you’ll need to learn in this category:

Bash scripting
Cronjobs or Crontab (Task scheduler)
Networking (Firewall and connectivity)
Basic file system and navigation
File and content search
SSH and storage

If you don’t know what some of these are, it’s OK! Anything unknown at this moment can definitely be learned.

If you’re new and want to start learning Linux operating systems, KodeKloud has a great Linux beginners course. If you’re more seasoned and want to further, improve or validate your skills in the subject, you can get the Linux Foundation Certified System Administrator Certification.

This certificate is globally recognized and will be a great addition to your career as a DevOps engineer. KodeKloud also offers an amazing preparation course to help you nail this certification with flying colors.

If you're unsure where to start, you can refer to the Linux learning path to help you understand the order in which to take these courses.

2. Programming Language

Part of your task as a DevOps engineer would be creating a lot of different scripts. That’s why learning a programming language is necessary. In the DevOps community, two languages are at the top of the list: Golang and Python.

Why Learn Golang

Golang or Go is an open-source programming language supported by Google. Its syntax is simple and clean, making it easier to learn for beginners. One of the main features of Go is concurrency and automated garbage collection. Concurrency is the ability to process lines of code in parallel and in a multi-threaded fashion.

Go achieves concurrency natively, making it faster, and the automated garbage collection capability ensures its lightweight state and stability. Another reason you should learn the Go language is because DevOps tools, such as Docker, Kubernetes, Terraform, and Grafana, are written in Go. Understanding how these tools work under the hood will allow you to troubleshoot faster and even add more features to your tools.

Learn Golang the KodeKloud way: with video lectures, demos, exercises, and hands-on labs right on your browser. This course requires zero experience in programming or coding.

Why Learn Python

Python has been around for many years, and it’s one of the most versatile languages. It’s easy to learn due to its syntax, and there’s a lot you can do with it. Here’s a summary of what you can do with Python:

Web Development
Scripting
Software automation and testing
Machine Learning
Data Analytics

Of course, you are not required to learn all of these. What you should focus on as a DevOps engineer is scripting, software automation and testing, and, lastly, web development. You'll most likely be working on these areas as a DevOps engineer.

Getting certified in Python will definitely take you far and will open opportunities in your DevOps career. A certification will validate that your Python skills meet the global standards set by the Python Institute.

If you want to learn Python, KodeKloud has courses that will help you prepare for PCEP and PCAP.

For PCEP – Certified Entry-Level Python Programmer certification.

It will be beneficial to learn both of these programming languages. If you are unsure which one to start first, don't worry! KodeKloud has got you covered. You can follow the KodeKloud programming learning path!

3. GIT Versioning

GIT is a version control software that’s commonly used to store and keep track of any changes to your source code. In DevOps, you’ll mostly be working with application code repositories, script files, and infrastructure manifest or definition files. All of which would be stored in git repositories. This allows you to maintain and monitor any changes that have been made and also easily revert back to any version in case of issues. This makes the application or infrastructure more stable and able to recover from crashes.

You don’t need to have advanced knowledge in GIT, but just enough for you to be able to pull and push code to the repository. Learning GIT is a must for any position that’s IT-related and that includes DevOps engineers. The popular repositories in this aspect are GitHub and GitLab.

If you're someone who’s not yet familiar with the subject or just wants to refresh their knowledge in GIT, KodeKloud has a fantastic beginner course that includes everything you need to learn to get started with using GIT in your workflow.

4. CI/CD (Continuous Integration/Continuous Delivery) Tools

CI/CD tools are used to automate the interaction from the software developer pushing code to your repository to the deployment of the said code changes to their respective environments. This, in turn, speeds up the process of delivering software to your end users.

In DevOps, where automation is key to every process, learning CI/CD tools is a must. Here’s a list of the DevOps community's top 5 most widely used CI/CD tools:

Jenkins: An open-source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery.
GitLab: A central DevOps platform. It helps you automate your code's builds, integration, and verification.
CircleCI: A CI/CD tool that supports rapid software development and publishing. It allows automation across the user’s pipeline, from code building and testing to deployment.
TeamCity: This is a CI/CD server offering from JetBrains, makers of heavily robust IDE such as PyCharm and PHPStorm.
Bamboo: This is a continuous integration build server from Atlassian that performs an automatic build, test, and release in a single place.

You don’t have to learn all the tools listed here, as this usually depends on many factors. However, if you’re just starting out, there’s nothing wrong with going for the most prominent tool, which is Jenkins.

Jenkins has been around for a long time and also has a large community behind it. It also has a huge library of plugins that answer most of the features you want in CI/CD. KodeKloud has a complete Jenkins course. It covers everything you need to know to get started with the most popular CI/CD tool.

5. Infrastructure-as-code (IaC)

Infrastructure as code is an infrastructure management approach where your software infrastructure is defined or created using manifest files. Gone are the days when IT administrators or DevOps engineers set up servers by manually installing packages or applications for the servers to be provisioned. With IaC, we define each attribute or property of how we want the server to be in a small text file, and then an IaC tool automatically spins up a server based on the values declared.

This allows servers to be set up in seconds. It also allows hundreds or even thousands of servers to be uniformly provisioned quickly from a single manifest file.

Here are the top 5 most popular IAC tools:

Terraform: It is one of the widely used IaC tools. Top cloud providers such as AWS, GCP, and Azure support it.

Ansible: It is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code.
Chef - is an IAC automation tool written and built on the Ruby language
Puppet - It is an IaC that enables you to easily deploy and manage infrastructure.
AWS CloudFormation - This is an AWS IAC service offering.

For this category, you don’t have to gain expertise in all of these, but it will be helpful if you at least cover the basics for each one. This way, it will be easier for you to adapt to any tools that you come across, as this may become different depending on what’s currently being used by your company. The great thing about these tools is that they’re easy to learn since they all follow the core concept of IaC.

If you wish to learn the basics, you can refer to these great courses from KodeKloud:

If you wish to gain a deeper knowledge of these tools or are interested in getting certified, Terraform and Ansible have certifications available. Go the extra mile and further validate your skills. These courses from KodeKloud can help you prepare for the certification:

Now, that's a lot of tools to learn in this category. It might be confusing for someone starting out which tool to learn first. Fortunately, KodeKloud already prepared a great IaC learning path that's logically organized.

6. Containers and Container Orchestration

Software containerization has become the mainstream method of building and deploying applications. It allows your software to be packaged with all the dependencies required to run. There are many containerization tools out in the market, but the most popular one is Docker.

Understanding how containers work and how they are built is a very integral skill for DevOps engineers. Since most software applications are now served in containers, containers will likely be a part of the entire DevOps infrastructure in your company.

To start learning Docker, enroll in our Docker Training Course for the Absolute Beginner.

If you’re already familiar with Docker and want to delve into advanced topics and get certified, you can check out KodeKloud Docker Certified Associate Exam Course. These two courses will prepare you for everything you need to know to be an expert with containers.

Container Orchestration is the automated process of managing and running your container services or applications. It deals with deployment, load balancing, and scaling, enabling your software infrastructure to have high availability, resilience, and the ability to recover from any crashes or failures. One of the popular tools for orchestrating your containers is Kubernetes.

Kubernetes has many features and can be quite complex once you get into the advanced features. However, once you have gained proficiency with containerization tools like Docker, you should be able to grasp what Kubernetes is all about quickly. To start learning Kubernetes, enroll in our Kubernetes for the Absolute Beginners course.

7. Cloud Platforms

Businesses have been moving towards cloud platforms for some time now. Cloud platforms answer most, if not all, of the issues of on-premise infrastructure. This includes the high cost of hardware, scalability challenges, and complex maintenance, further adding up the charges.

With cloud platforms, most of these high overhead problems are maintained by the actual provider, leaving the business to focus on the application and data itself. The pay-as-you-use model with these cloud platforms allows companies to scale up and down their services as needed to attain cost-efficiency while providing great quality software.

As a DevOps engineer, you’ll most likely be working with cloud providers to build the foundation for your infrastructure. Having the knowledge and the skills necessary to develop, manage, and utilize the different services offered by cloud platforms is a very important skill. Learning cloud platforms is all about gaining proficiency and familiarity with the different services within their platform.

This, in turn, allows you to determine the exact service that will be suitable to solve a particular requirement cost-efficiently. Here are the most popular cloud platforms that you should add to your skill set as a DevOps engineer:

Amazon Web Services (AWS)
Google Cloud Platform (GCP)
Microsoft Azure

If you’re already working as a DevOps engineer, chances are that the company you’re working for already has an infrastructure running on either of these platforms. It’s also possible to have multi-cloud platforms. The best approach would be to gain further knowledge of what's already available or used by your company.

KodeKloud's Cloud learning path has courses that will introduce you to the inner workings of the AWS popular offerings ECS and AWS Lambda.

The path also has courses that will help you prepare for certifications such as:

It is recommended to gain enough (just to cover the basics) knowledge in all of them. This gives you the flexibility to work in any cloud platform, further amplifying your credibility as a DevOps engineer.

Special Mentions

Once you have gained proficiency in this article's major categories, I recommend focusing on improving on these next.

Package Managers for popular programming languages - This requires understanding how applications written in different languages are built. Knowledge of these allows you to build applications in production-ready containers.

PyPi for Python
Maven or Gradle for Java
Composer for PHP
NPM for Javascript

Web Servers - As more services are served in web applications, either on mobile or computer, a DevOps engineer may be required to set up web servers and apply the proper configuration. You should, therefore, be familiar with the following:

Nginx
Apache
NodeJS

Written and verbal communication skills - This skill will be very valuable, especially in job interviews. DevOps engineers would sometimes be required to perform some kind of reporting, maybe a performance report or a cost-analysis report. Being able to convey this complex, jargon-heavy information in a format that’s easy to understand by your non-technical managers.

Conclusion

From this article, you can see why DevOps engineers are highly paid and highly sought after. The sheer amount of technical prowess they deal with daily speaks volumes about the value they add to any company.

This article should provide the guidance you’ll need to get started if you’re aiming for a career in DevOps. If you are already in the industry, this could also serve as a checklist of what you’ll need to work on next to improve your skills further.
