Kubernetes is one of the most popular tools for container orchestration that help manage containers at scale.

The Certified Kubernetes Administrator (CKA) is a certification developed by The Linux Foundation and the Cloud Native Computing Foundation (CNCF) for Kubernetes administrators, cloud administrators, and other IT professionals who manage Kubernetes instances.

Kubernetes has been there for less than a decade but has grown in popularity to be one of the most loved platforms in the world. It is one of the most preferred systems by businesses operating on cloud platforms and technology. It automates the deployment, management, and scaling of containerized applications. 

Below are four primary reasons why people love Kubernetes:

  • Kubernetes is a fully open source platform, unlike other container orchestration tools. 
  • The software not only runs on the cloud but can even run on-prem, in a colocation facility, or even in all these places at once as a hybrid cloud solution.
  • Kubernetes is a powerful tool that uses code to define or manage every aspect of the software. It makes processes more scalable, reliable, and repeatable.
  • It is less fragmented than others, as the skills and resources of Kubernetes can be reused across various environments or configurations.
