Why should I get certified in Kubernetes?

Kubernetes certifications can be a good signal to employers that you can work effectively with one of the most powerful tools in cloud computing, among several reasons. Here are many reasons why people pursue them.

1. High job demand

Kubernetes skills are consistently listed in top-paying DevOps and cloud job roles. Certified professionals stand out in a competitive hiring market. As more organizations move towards containerization and microservices, the demand for Kubernetes expertise will only continue to grow.

2. Proof of practical skill

Completing a certification program can be a good representation of practical skill, which is highly sought after in a technical field.

For example, certifications like Certified Kubernetes Administrator (CKA) and Certified Kubernetes Application Developer (CKAD) are performance-based. This will guide you through to complete real-world tasks in a live environment, proving you can do the job, and not just pass a multiple-choice test.

3. Better pay

When it comes to hiring Kubernetes professionals, 1 in 10 job positions include the need for certification. And, AWS certifications in Kubernetes have been mentioned almost 45% of the time. This would mean that attaining a certification can lead to a higher chance of getting hired in a competing company. This may lead to better opportunities for higher salaries.

Kubernetes certifications for beginners, intermediate, and advanced practitioners

The following guide categorizes Kubernetes certifications into three levels — Beginner, Intermediate, and Advanced — with details on exam costs, prerequisites, ideal candidates, and training providers.

Roadmap for certifications and training

If you're unsure where to start, here’s a suggested roadmap:

Beginner-level certifications

Beginner-level certifications are meant for individuals who have a basic understanding of Kubernetes and its concepts. These certifications can be a great starting point for those looking to enter the world of cloud computing and container orchestration.

Here are some of the most common certifications:

1. Kubernetes and Cloud Native Associate (KCNA)

The Kubernetes and Cloud Native Associate (KCNA) certification is offered by the Cloud Native Computing Foundation (CNCF). This is a beginner-level certification that covers the fundamentals of Kubernetes and cloud-native technologies. It is designed for individuals with little or no experience in using Kubernetes.

• Cost: The exam costs $250. For learning under the Linux Foundation, the course and exam bundle costs $299. For a combination of the certification and a subscription to unlimited access to e-learning + SkillCreds, it would cost you $495.
• Prerequisites: As this is meant to be an entry-level course, there are no prerequisites.
• Ideal for: Students, beginners, and IT professionals new to cloud-native technologies
• Exam format: 90-minute online multiple-choice exam, with one retake attempt
• Topics covered: Kubernetes basics, cloud-native ecosystem (e.g., containers, microservices), and CI/CD and observability tools

KCNA is the best place to start if you're new to Kubernetes or looking to understand the broader cloud-native landscape. The certification will remain valid for two years before it expires.

2. Google Cloud Digital Leader

The Google Cloud Digital Leader certification is designed for beginners who want to be exposed to Google Cloud's core products and to demonstrate their knowledge of cloud computing basics. This certification would cover other areas beyond using Kubernetes with Google Cloud Platform (GCP).

• Cost: A standard exam would cost $99 plus tax, and a renewal exam would cost $60 plus tax.
• Prerequisites: None, but having some experience collaborating with technical professionals would be recommended.
• Ideal for: Beginners exploring cloud platforms with light exposure to Kubernetes
• Exam format: Multiple choice, either through online or on-site proctoring
• Coverage: Cloud infrastructure, Kubernetes on GCP, and security, billing, and cloud operations

This certification is a good introduction suitable for business stakeholders and early-career professionals who want a good focus on Google Cloud products beyond just using k8s. Certificates are valid for 3 years.

Intermediate-level Kubernetes certifications

Intermediate-level certifications are aimed at those who have a good understanding of cloud platforms and are looking to expand their skills and knowledge. These certifications require more technical knowledge and hands-on experience, making them ideal for professionals who are ready to dive deeper into Kubernetes.

Here are some examples of such certifications:

3. Certified Kubernetes Administrator (CKA)

The Certified Kubernetes Administrator (CKA) certification is designed for professionals who want to demonstrate their ability to design, install, configure, and manage Kubernetes clusters. The exam covers a wide range of topics, including cluster architecture, networking, security, storage, troubleshooting, and more. It also requires hands-on experience with Kubernetes.
