Top DevOps Certifications by Category

What Do DevOps Professionals on Reddit Really Think?

Before we dive into the list, let’s address the big question: Do hiring managers actually care about certifications? We analyzed discussions from forums like r/devops to get the real-world answer.

The consensus is nuanced and incredibly valuable:

• “Certs Get You the Interview, Experience Gets You the Job.“ This is the most common sentiment. Certifications are HR filters. They use keywords like “AWS,” “CKA,” or “Terraform” to scan resumes. A certification proves you have a validated baseline of knowledge and gets you past the first gate. The technical interview, however, is where you prove your real experience.
• “There is No ‘Best’ Cert.” The best DevOps certification is the one that aligns with your specific goals. The consensus is clear:
  • Cloud is King: The AWS Certified DevOps Engineer – Professional or Azure DevOps Engineer Expert is often seen as the most valuable if you are committed to that ecosystem. The advice is to “pick the cloud your company uses, or the one you want to work for.”
  • CKA is the Hands-On Standard: The Certified Kubernetes Administrator (CKA) is universally praised. Why? Because it’s 100% hands-on. You can’t fake it. It proves you can actually do the job, not just answer multiple-choice questions.
  • Terraform is Foundational: The HashiCorp Certified: Terraform Associate is seen as a non-negotiable, foundational cert for any modern infrastructure or DevOps role. It’s the standard for Infrastructure as Code (IaC).
• “Don’t Get a Cert for a Tool You’ve Never Used.” Real-world professionals advise using certifications to validate and structure your learning, not as a replacement for it. The knowledge gained while studying for the exam is almost always more valuable than the PDF certificate itself.

The Verdict: Yes, the top DevOps certifications are absolutely worth it. They are a necessary tool for navigating the modern job market, provide a structured learning path, and prove your skills in a verifiable way.

Top 14 DevOps Certifications: A Detailed Breakdown

Now, let’s look at each of the top DevOps certifications in detail. I’ve grouped them by their core function in the DevOps lifecycle.

Group 1: Container Orchestration (The “Must-Haves”)

Kubernetes is the de facto standard for container orchestration. These CNCF (Cloud Native Computing Foundation) certifications are 100% hands-on, performance-based, and highly respected.

1. Certified Kubernetes Administrator (CKA)

The CKA is my #1 pick for a hands-on, in-demand credential. It is a sought-after certification from the CNCF. As per the CNCF’s annual report, the CKA exam hit 176,000 enrollments in 2023 alone, proving its dominance.

This certification is aimed at sysadmins and DevOps engineers who manage, set up, and troubleshoot production Kubernetes clusters. It’s a challenging 2-hour practical exam where you solve real-world problems on the command line.

2. Certified Kubernetes Application Developer (CKAD)

While CKA is for administrators, CKAD is for developers. This certification focuses on designing, building, and deploying cloud-native applications on Kubernetes. If you are a developer who needs to containerize your app, write manifests, and deploy it, this is the cert for you.

3. Certified Kubernetes Security Specialist (CKS)

This is the advanced, expert-level certification for Kubernetes security. It focuses on security best practices, from building secure images (supply chain security) to configuring cluster security (hardening, NetworkPolicies, RBAC) and runtime security (using tools like Falco).

Crucially: You must have a valid CKA certification before you can attempt the CKS.

Group 2: The Big 3 Cloud Platforms (The “Giants”)

As the Reddit community agrees, your cloud platform knowledge is paramount. These are the top-tier DevOps certifications from AWS, Microsoft, and Google.

4. AWS Certified DevOps Engineer – Professional

This certification validates deep technical expertise in provisioning, operating, and managing distributed application systems on the AWS platform. It’s a “Professional” level exam, meaning it’s challenging and requires significant hands-on experience. It covers CI/CD, monitoring and logging, security, and high availability.

A Real-World DevOps Certification Roadmap

When we talk about a “DevOps roadmap,” it’s really a path of certifications related to DevOps practices. Based on my experience and real-world advice, here is a practical roadmap.

1. Start with Your Base: Your first cert should be closely related to your existing domain or your target job.
   • If you are a System Admin: Start with LFCS or RHCE (Ansible) to build on your Linux skills.
   • If you are a Developer: Start with DCA (Docker) and then move to CKAD.
   • If you are in IT Operations/Help Desk: Start with a cloud-platform fundamental cert, like AWS Cloud Practitioner or Azure Fundamentals (AZ-900).
2. Pick Your Cloud: You must learn a major cloud platform. Pick one (AWS, Azure, or GCP) and pursue its DevOps certification path (e.g., AWS DevOps Engineer – Professional).
3. Learn IaC: Get the HashiCorp Certified: Terraform Associate. This is a non-negotiable skill for almost all modern DevOps roles.
4. Master Containers & Orchestration: Get the Certified Kubernetes Administrator (CKA). This is the new “Linux” — a foundational skill for the entire cloud-native ecosystem.
5. Specialize: Once you have the foundation (Cloud + IaC + Kubernetes), specialize in a high-demand area:
   • Security: Get the HashiCorp Vault Associate and then the CKS.
   • Observability: Get the Prometheus Certified Associate (PCA).
   • Service Mesh: Get the Istio Certified Associate (ICA).

Most In-Demand DevOps Certifications

While all the certs on this list are valuable, a few are consistently in the highest demand in terms of job postings and salary.

Based on current DevOps trends, the most in-demand certifications are:

1. AWS Certified DevOps Engineer – Professional
2. Certified Kubernetes Administrator (CKA)
3. Microsoft Certified: DevOps Engineer Expert (Azure)
4. HashiCorp Certified: Terraform Associate

How Long Does It Really Take to Learn DevOps?

This is a common question, but DevOps is a culture and a set of practices, not a single tool.

• You can learn the core concepts (principles, CI/CD, version control, containerization) in 2 to 5 months of dedicated study.
• Reaching the next level, where you can gain a deep understanding of the tools and build solutions for an organization, takes continuous learning and hands-on experience over several years.

Conclusion

Based on my 10+ years of working as a DevOps engineer with multiple certifications, I can say that there is no single certification that fits all the required DevOps skills. The field is a collection of practices and tools.

Based on your career path, you must choose a certification that aligns with your goals.

• If you are on the DevOps Engineer/SRE/Ops path: The CKA is your best bet.
• If you are a Developer: The CKAD is the clear choice.
• If you are moving into DevSecOps: The CKS and Vault Associate certs are your target.
• If you are just starting: The KCNA or a cloud fundamentals cert is the best entry point.

In this blog, we have looked at the top DevOps certifications for you to showcase your knowledge. I highly recommend you build your own practice labs (a kubeadm cluster setup is excellent for CKA) and use high-quality practice materials from sources like PassITExams to ensure you are ready for the high-stakes, hands-on exams.
