What are the Best Kubernetes Certifications?

1. Certified Kubernetes Administrator (CKA)

CKA is my #1 choice for Kubernetes certification.

CKA certification is a sought-after certification when it comes to DevOps Engineer Jobs. Whether you are an experienced IT professional or a fresh college graduate, CKA certification will add value to your resume. It is mainly due to the nature of the exam. Unlike other certifications where exams have multiple-choice questions, CKA is a hands-on certification exam where you need to solve Kubernetes tasks and solve cluster issues from the command line. This certification is aimed at sysadmins and DevOps engineers who are involved with day-to-day Kubernetes operations.

The Certified Kubernetes Administrator (CKA) program provides assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators.

2. Certified Kubernetes Application Developer (CKAD)

I recommend CKAD certification for all developers & engineers who focus more on cloud-native microservices application development & deployment.

CKAD certification focuses more on the application aspects of Kubernetes. If you are a developer or a Devops engineer who wants to showcase your ability to deploy applications on Kubernetes with cloud-native best practices, CKAD certification is for you.

The Certified Kubernetes Application Developer (CKAD) exam certifies that candidates can design, build and deploy cloud-native applications for Kubernetes.

3. Certified Kubernetes Security Specialist (CKS)

CKS exam is recommended for engineers involved in cloud-native security.

CKS certification focuses more on Kubernetes security. When it comes to containerized environments, security plays a key role. From building a container image to deploying it on kubernetes, security best practices have to be applied to reduce the attack surface. This certification covers the security aspects from building images to deployment. You have to learn container security best practices and associate cncf security tooling such as Falco and Trivy to prepare of this exam.

The Certified Kubernetes Security Specialist (CKS) program provides assurance that a CKS has the skills, knowledge, and competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime. CKA certification is required to sit for this exam.

4. Kubernetes and Cloud Native Associate (KCNA)

KCNA is recommended for students, IT managers, and engineers who need foundational knowledge of the cloud-native ecosystem.

KCNA exam focuses on Kubernetes and related tools in the cloud-native landscape. This exam is easy as compared to CKA, CKAD, and CKS. It is a multiple-choice exam with 60 questions and a 90 minutes exam time.

The Kubernetes and Cloud Native Associate (KCNA) exam demonstrates a user’s foundational knowledge and skills in Kubernetes and the wider cloud native ecosystem.
