4 Best Kubernetes Certifications Program in 2024

In traditional systems, an application developed in one computing system often did not run efficiently on other computing systems. Also, as organizations run multiple applications on the same physical server, the occurrence of continuous resource allocation issues is merely inevitable.

There are instances when one application would consume too many resources due to which the other applications could not run efficiently. Virtualization was introduced as a solution to this problem enabling running multiple VMs on a single server's CPU.

Containerization is currently a significant trend in the market, and its adoption is on the rise. At a higher level, a new software ecosystem is forming to enable containerization. Kubernetes is now growing along with containers, cloud development, and concurrent technologies, so are its job prospects for professionals who are curious about the technology and possess the necessary skills to use the same.

Let us see what is Kubernetes. 

What is Kubernetes?

Developed and designed by Google Kube or Kubernetes is an open-source container orchestration platform responsible for automating many of the manual processes involving deploying managing and scaling containerized applications. It is advantageous to use Kubernetes while optimizing app dev for cloud as it provides the platform to schedule and run containers on clusters of physical or virtual machines (VMs). 

Kubernetes allows us to:  

  • Orchestrate containers covering multiple hosts.
  • Efficiently utilize hardware to maximize the resources needed to run the apps. 
  • Automate and control deployment and updation of applications.
  • Add storage to run apps. 
  • Scale containerized applications 
  • Declaratively manage services, which guarantees the deployed applications are always running the way you intended them to run.
  • Health-check and self-heal your apps with auto-placement, auto-restart, auto replication, and autoscaling.

What is the Kubernetes Certification?

The Cloud Native Computing Foundation aims to grow the community of Kubernetes Administrators by permitting continued growth across companies and organizations using Kubernetes. Certification is the primary step in the process, allowing administrators to establish their credibility and value in the job market. It also facilitates companies to hire high-quality teams to support their growth quickly.

The purpose behind Certified Kubernetes Administrator (CKA) program is to assure that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators. It is an online, proctored, performance-based test that requires solving multiple issues from a command line.

Career Opportunities in Kubernetes

Right now, job titles do not reflect Kubernetes hiring. So, when you look for job roles for Kubernetes, focus on the job descriptions rather than the job titles. Certification in Kubernetes would make you front-runners for the following career opportunities, or you might like to switch your profession to one of these roles:

  • DevOps Engineer 
  • Cloud Engineer
  • Systems Engineer
  • Site Reliability Engineer
  • [Senior] Java Architect
  • [Senior] Python Developer
  • Software Escalation Engineer

Virtual Machines vs Containers

VMs allowed better utilization of resources, reduced hardware costs, and enforced better levels of security. Technically speaking,

“Virtual Machines are an abstraction of the hardware layer, meaning each VM has its copy of the operating system, CPU, filesystems, processing power, and memory.”

In simple terms,

“each Virtual Machine could be considered as a computer system running with all required hardware and software components.”

Containers are similar to Virtual Machines. But, containers are an abstraction of the Application Layer, meaning they simulate software applications while sharing a standard operating system. They are portable across clouds and Operating Systems as they decouple from the underlying infrastructure.

Containerized environments prove to be a better option to run applications as they require less space and memory. A typical virtual machine is some gigabytes in size and requires a few minutes to start. Containers, on the contrary, are mere megabytes in size and start in a couple of seconds.

The Need of Kubernetes

In the production environment, managing containers efficiently is an essential requirement. Kubernetes is an open-source platform - a container-orchestration system for automating application deployment, scaling, and management, to be exact - that helps to manage all of the containers. Kubernetes provides a framework so that distributed systems run resiliently.

Primary Highlights of Kubernetes

  • Container Deployments
  • Load Balancing, Service Discovery & Autoscaling
  • Persistent Storage

The Complete Android 12 & Kotlin Development Masterclass


Kubernetes is emerging as the platform of choice, a desirable operating system for the cloud. Although this should be clear that not in the classical sense, but from the perspective of a distributed, cloud-native application.

Owing to the rise in the adoption and popularity of Kubernetes, all major cloud providers are now offering their own native Kubernetes services and Kubernetes-based services. With new releases getting dropped frequently and more and more vendors adopting the open-source container-orchestration system, it is obvious that Kubernetes is heading high.

The emergence of new and exciting job roles and career prospects for Kubernetes is, thus, natural at this point. So, for a rewarding future and career, learning Kubernetes is, of course, nothing less than an appealing option.
