Top 5 Free Courses to Learn Kubernetes for Developers and DevOps Engineers in 2024 - Best of Lot

Hello guys, DevOps is becoming an essential skill in today's Programming and Software Development world and Kubernetes is an important concept and tool for DevOps engineers. It takes container-based deployment to another level and allows you to manage it on the scale. You can use Kubernetes to scale your container environment or let Kubernetes do all the work for you by leveraging its auto-scaling feature. Many DevOps beginners think that Docker and Kubernetes are the same but they are not. Docker provides a container to deploy your application and commands to interact with those but container but Kubernetes is actually a container management technology, which decides how many containers are needed and deal with other management aspects.

In fact, Kubernetes or K8s is arguably the most important container management technology in the world at this moment and you shouldn't be surprised that the roots of Kubernetes lie in Google itself.

It's not a Google tool but created by a couple of Google developers as an open-source alternative of similar tools they have used in Google to manage containers at scale.

Kubernetes comes with some mind-boggling features like auto-scaling, it's very reliable, and also an extremely powerful container orchestration engine, probably the best at this moment.

It allows you to convert your infrastructure into a Container as a Service (Platform), bringing in some of the awe-inspiring features like Zero Down Time Deployments, Fault Tolerance, Auto Scaling, Cloud and Storage integrations, which were extremely difficult to implement.

More and more people are realizing the importance of DevOps and learning tools like Jenkins, Docker, and Kubernetes and if you also happen to be in the same boat then these free courses will provide you the springboard you need to jump into the DevOps world.

Btw, if you don't mind spending few bucks for learning something as valuable as Kubernetes, then I suggest you also check out Docker and Kubernetes: The Complete Guide course on Udemy, it's not free but you can get it for just $10 on many Udemy flash sales which happens every month. You will learn both Docker and Kubernetes, which means you can kill two birds with just one stone. It is the perfect course to start with both Docker and Kubernetes in 2024.
