The answer moves with two things: how much you already touch production systems and which cloud your employer runs. The fees behind the best devops certifications stretch from a little over $70 for a Terraform Associate exam to roughly $500 for a Red Hat performance exam, and the study time runs from a few weeks to a few months. This guide ranks the seven credentials that show up most often in job ads, with costs, exam formats and the roles each one unlocks, so you can pick one and start this month.
No single certificate makes you a DevOps engineer. The best devops certifications are the ones that prove a skill your next job actually screens for.
Which best devops certifications do employers ask for most?
Job ads cluster into three families. Containers and Kubernetes cover the runtime side, infrastructure as code covers how servers get built, and platform automation covers the pipelines that move code. These are the best devops certifications for 2026 because each one maps to tools that appear in real job ads. The table below ranks them by how often they show up in postings and by the roles each one opens. Prep times are planning estimates for someone studying two evenings a week, and they assume real lab time.
| Certification | Price | Exam format | Prep time | Roles it unlocks |
|---|---|---|---|---|
| CKA Certified Kubernetes Administrator | $445 with one free retake | 2 hour live cluster, hands-on | 6 to 8 weeks | Platform engineer, SRE, Kubernetes admin |
| CKS Certified Kubernetes Security Specialist | $445 with one free retake | 2 hour live cluster, hands-on | 6 to 8 weeks after CKA | Cloud security, DevSecOps |
| Terraform Associate | $70.50 plus tax | 1 hour multiple choice | 4 to 6 weeks | Infrastructure as code engineer |
| Docker Certified Associate | $199 | 90 minutes, 55 questions | 3 to 4 weeks | Container engineer, junior DevOps |
| AWS DevOps Engineer Professional | $300 | 180 minutes, 75 questions | 10 to 14 weeks | Senior platform and release engineer |
| Microsoft AZ-400 DevOps Engineer Expert | $165 | 100 minutes, scenario questions | 8 to 12 weeks | Azure pipeline and release engineer |
| Red Hat RHCE with Ansible | About $500 in the Red Hat Learning catalog | Hands-on, no multiple choice | 8 to 12 weeks | Linux automation, RHEL platform |
Read the job descriptions before you pick. Our guide to what a DevOps engineer does in 2026 lists the tools employers name most often, and DevOps engineer roles and responsibilities splits the work into platform, pipeline and reliability tracks. If pay is the deciding factor, Docker and Kubernetes fresher salary for 2026 shows what these skills are worth at the start of your career.
How much does each DevOps certification cost in 2026?
The Cloud Native Computing Foundation charges $445 for the CKA, and the CKS costs the same $445. Both prices include one free retake, which is rare in this field. Mirantis charges $199 or 200 EUR for the Docker Certified Associate, and one payment covers one attempt with no free second try.
HashiCorp charges $70.50 plus local tax for the Terraform Associate, and the exam page says no free retake is included. AWS charges $300 for the DevOps Engineer Professional, while Microsoft charges $165 for AZ-400 in the United States. Red Hat sells EX294 through the Red Hat Learning catalog, where the exam alone and the exam plus course carry separate prices, and training guides quote about $500 for the standalone exam.
Two discounts change these numbers. Once you hold one AWS Certification, AWS gives you 50 percent off the next exam, which takes the Professional DevOps exam down to $150. Red Hat Learning subscribers get exam access included in the subscription, and the Linux Foundation exam bundles come with practice simulator sessions.
How long is each exam and how hard is it?
Format tells you what kind of preparation you need. The CKA and CKS are two hour, online proctored, performance-based exams on a live cluster, so there is no multiple choice to game. The CKA blueprint puts Troubleshooting at 30 percent, with Cluster Architecture at 25 percent, Services and Networking at 20 percent, Workloads and Scheduling at 15 percent, and Storage at 10 percent. KodeKloud's CKA course runs about 25 hours of video across 309 lessons, and the exam purchase includes two Killer.sh simulator sessions that mimic the real environment.
The CKS covers six security domains. Supply Chain Security, Microservice Vulnerabilities and Runtime Monitoring each carry 20 percent, while Cluster Hardening and System Hardening carry 15 percent each and Cluster Setup carries 10 percent. That mix rewards candidates who can lock down a running cluster rather than recite definitions.
| Exam | Length and questions | Pass signal | Hardest part |
|---|---|---|---|
| CKA | 2 hours on a live cluster | Not published by CNCF | Speed under a timer |
| CKS | 2 hours on a live cluster | Not published by CNCF | Multi step security tasks |
| Docker Certified Associate | 90 minutes, 55 questions | Not published by Mirantis | Storage and networking detail |
| Terraform Associate | 1 hour, multiple choice | Not published by HashiCorp | State and module questions |
| AWS DevOps Engineer Professional | 180 minutes, 75 questions | 750 out of 1000 | Multi account design |
| Azure AZ-400 | 100 minutes, scenario based | 700 out of 1000 | Security and compliance design |
Microsoft publishes a passing score of 700 out of 1000 for AZ-400, while AWS scores the professional DevOps exam on the same 1000 point scale with 750 to pass. CNCF, Mirantis and HashiCorp do not publish cut scores for their exams at all, so treat any number you see online for those three as an estimate.
Which certification should you take first with no experience?
Start with the cheapest exam that proves you can use the tools. The Terraform Associate costs $70.50 and takes one hour, so it is the lowest risk way to find out whether infrastructure as code interests you. If you have never touched containers, the Docker Certified Associate at $199 fits into three or four weeks of evening study and is designed for people with 6 to 12 months of Docker work.
Do not skip the fundamentals. A cloud fundamentals exam gives you the vocabulary that every later DevOps exam assumes. Our comparison of DevOps on AWS versus Azure explains why the platform you learn first decides which certification buys you the most, and the same guide shows the pricing of the services you will use in labs.
What order works if you already run production systems?
If you already ship code, the order that pays back fastest runs from operations depth to platform breadth. The Kubernetes path goes CKA first, then CKS, because the CNCF says CKS candidates must have passed the CKA before they can book, although the CKA does not need to be an active certificate. The cloud path goes Terraform Associate first, then the AWS DevOps Engineer Professional, because AWS asks for two or more years of hands-on experience and a good deal of scripting for the professional exam.
The Red Hat route runs through RHCSA and then EX294, since Red Hat expects system administration skills before it expects Ansible playbooks. Ansible skills also translate directly into the pipeline work that many teams call release engineering. If your employer runs Red Hat Enterprise Linux, this path pays off faster than any cloud credential.
Which credential is worth the money and which one is not?
The Docker Certified Associate is the weakest signal in the table, and the reason is simple. Docker sold its enterprise business to Mirantis, which now runs the exam, and recruiters have mostly moved on to asking for Kubernetes skills instead. It is still a fine, cheap way to prove container basics, so take it only if you need a fast entry-level badge.
Certifications also do not replace proof of work. Interviewers ask what you built, how it broke and what you changed, so keep a small pipeline or cluster running and write about it. Understanding how DevOps differs from Agile delivery helps you answer those questions well, and our Agile versus DevOps comparison for 2026 gives you the wording.
Pick one credential from the table that matches the tools in your target job ads, and give it one full study cycle. The best devops certifications stack well, so each one answers a question the previous one could not. Add the next badge only after the first one is on your resume and your lab work matches what the exam tested.
