Are You Wishing to Get Started Learning DevOps This Year?

I’ll be giving you a quick five-minute guide on how to get yourself started learning DevOps this year. By the way, DevOps is one of the most sought-after IT skills this year, and gaining the right skills can easily give you the opportunity to occupy a role related to cloud computing and DevOps.

Understanding DevOps

Now, how do you get yourself started with DevOps? Let me begin this video by giving you some very important things to understand regarding the term “DevOps.”

DevOps is a practice that involves two major teams: the development teams and the operations teams. The development teams consist of the developers who write application code. This code can be written in various programming frameworks, such as Python, C, Java, and .NET.

When I talk about applications, you might wonder what an application is. Your YouTube app, Facebook, Zoom, and Microsoft Teams are all applications, and they are built using specific programming frameworks. The development teams responsible for writing this code work together with the operations teams, which include DevOps engineers, code testers, and quality assurance engineers.

The first thing you must understand is that DevOps is a practice that combines these development and operations teams to effectively and efficiently improve the entire lifecycle of the software development process. This basic understanding is crucial as you embark on your DevOps journey.

Key Concepts in DevOps

If you want to get started with DevOps and cloud computing, there are some key things you must understand. DevOps, being a practice, involves a set of tools that help enforce the principles that guide this practice.

If you’re looking to get started with DevOps or if you’ve been studying it but are unsure if you’re gaining the right knowledge, check the link in my channel description. I have a special end-to-end DevOps course that can help you understand these concepts, starting from basic DevOps principles like version control to advanced topics like CI/CD.

Principles of DevOps

Remember, DevOps is a practice guided by several principles. Some of these principles include:

Continuous Integration (CI)

Continuous Deployment (CD)

Infrastructure as Code (IaC)

Continuous Monitoring

Collaboration and Communication

With these principles in mind, what are the key tools you must master to get started with DevOps this year?

Essential Tools for DevOps

The very first tool I recommend is learning a version control system, such as Git. This is a fundamental concept for beginning your DevOps journey.

You must also have a basic understanding of a cloud platform. You cannot effectively be a DevOps engineer without at least an intermediate understanding of a cloud platform, as many resources you will provision will be on platforms like Microsoft Azure, Amazon Web Services (AWS), or Google Cloud.

After understanding a cloud platform, familiarize yourself with different build tools. For Java-based applications, these include:

Apache Maven for builds

SonarQube for code analysis

Nexus Repository for artifact management

Prometheus for continuous monitoring

Grafana for visualization or dashboarding

You should have a solid understanding of these build tools to work with various applications.

Once you’re comfortable with these tools, look into continuous integration and continuous deployment technologies like Jenkins. However, you don’t need to learn all the tools at once. For each principle, pick one tool and master it.

For version control, choose GitHub. For a cloud platform, pick either AWS or Azure. For continuous deployment, you might choose Jenkins or GitHub Actions. I always recommend starting with Jenkins. After learning Jenkins, you should learn container management tools like Docker, and most importantly, Kubernetes as a container orchestration tool.

These are the key technologies that, if mastered, will enable you to effectively defend your skills as a DevOps engineer during technical conversations or interviews.
