Docker & Certified Kubernetes Administrator (CKA)

What Is Container (Docker)?

Containers are a software package into an invisible box with everything that the application needs to run. That includes the operating system, application code, runtime, system tools, system libraries, and etc. Docker containers are built off Docker images.

Docker is an open-source platform based on Linux containers for developing, shipping, and running applications inside containers. we can deploy many containers simultaneously on a given host. Containers are very fast and lightweight because they don’t need the extra load of a hypervisor because they run directly within the host machine’s kernel.

What Is Kubernetes?

In organizations, multiple numbers of containers running at a time so it is very hard to manage all the containers together we use Kubernetes. Kubernetes is an open-source platform for managing containerized workloads and services. Kubernetes takes care of scaling and failover for your application running on container.

What Are The Benefits Of Kubernetes Certification?

A Kubernetes certification makes your resume look good and stand out from the competition. As companies rely more and more on Kubernetes, your expertise will be an immediate asset.

top certification like the CKA (Certified Kubernetes Administrator) gives you the mighty potential for a better salary. Passing these exams is not an easy task, so companies seeking k8s engineers are willing to pay more.

After passing the exam, Kubernetes concepts become simple and almost second-nature.
