Which DevOps certifications do employers actually value? CKA, AWS DevOps Professional, AZ-400, Terraform and more, ranked by hiring signal with costs and caveats.
Here is a fact that quietly reorders every "top DevOps certifications" list: several of the certifications those lists still recommend no longer exist. The Docker Certified Associate has been discontinued with no successor, Microsoft retired the AZ-204 developer exam in 2026, and AWS renamed its SysOps credential entirely. DevOps is the fastest-churning corner of the certification market, so the first quality test of any ranking — including this one — is whether the exams on it can still be booked.
Short answer: the DevOps certifications with the strongest hiring signal in 2026 are the Certified Kubernetes Administrator (CKA), AWS Certified DevOps Engineer – Professional (DOP-C02), and Microsoft's DevOps Engineer Expert (AZ-400), supported by the HashiCorp Terraform Associate (004) as the best low-cost addition. Your primary cloud platform decides between the AWS and Azure options; the CKA is valuable regardless of platform.
Everything here is ranked by employer demand and signal strength. If you are looking for the stage-by-stage sequence to follow across a career, that is the territory of our guide to building a career roadmap with certifications rather than this comparison.
DevOps job listings rarely ask for a certification by name the way security or networking listings do. They ask for capabilities — Kubernetes, CI/CD pipelines, infrastructure as code, one or two cloud platforms — and certifications function as compressed evidence of those capabilities. So this ranking scores each credential on three questions:
For context on what the roles themselves pay: major US salary aggregators placed average DevOps engineer pay between roughly $123,000 (ZipRecruiter, August 2026) and $145,000 (Glassdoor, accessed August 2026) per year, with Indeed and Built In reporting around $134,000. Those are US averages for the role, not premiums attached to any certification — no verified figure exists for what a specific DevOps certification adds, and pay varies widely by location and experience.
The CKA sits at the top of this list because it is platform-neutral, hands-on and directly aligned with the centre of gravity of modern DevOps work. The exam is two hours of performance-based tasks in live Kubernetes clusters (currently based on v1.35), delivered online through the PSI Bridge proctoring platform, with a passing score of 66%. There are no prerequisites, and it is the mandatory gateway to the Certified Kubernetes Security Specialist (CKS) if you later specialise in security.
Know the terms before you buy: the exam lists at $445 USD, certifications earned since April 2024 are valid for two years, and renewal means a full retake — there is no continuing-education path. The purchase includes a 12-month eligibility window, one free retake and two sessions of the killer.sh simulator. The curriculum was revised on 18 February 2025 (Gateway API, Helm and Kustomize, CRI/CSI/CNI troubleshooting, Pod Security Standards), so discard any course built for the older syllabus. Developer-leaning candidates sometimes prefer the Certified Kubernetes Application Developer (CKAD), which shares the format and price but tests building and deploying applications on Kubernetes rather than administering clusters — pick by role, not by rumoured difficulty, since both are intermediate exams.
For AWS-platform roles this is the flagship. DOP-C02 is a Professional-tier exam: 75 questions in 180 minutes, $300 USD, passing at a scaled 750 on AWS's 100–1,000 scale. AWS recommends two or more years of experience provisioning and operating AWS environments plus a scripting background, though no prerequisites are enforced — you can legally sit it as your first AWS exam, even if few people should.
Two structural perks improve its value. Passing DOP-C02 automatically renews the AWS Developer Associate and CloudOps Engineer Associate certifications, and any active AWS certification gives you a 50% voucher off your next AWS exam. All AWS certifications run on a three-year validity cycle. When your preparation reaches the benchmark stage, working through timed AWS DevOps Engineer Professional practice questions will show you which of the exam's domains need another study cycle before you commit the $300.
One renaming to keep straight when you read older material: the AWS SysOps Administrator Associate was not scrapped — it became the AWS Certified CloudOps Engineer – Associate (SOA-C03) in September 2025, and it remains a sensible stepping stone towards DOP-C02.
Azure's counterpart credential covers designing and implementing DevOps processes across GitHub and Azure DevOps: source control strategy, build and release pipelines, security and compliance planning, and instrumentation. It is one of only two Microsoft certifications with a mandatory prerequisite — you must already hold Azure Administrator Associate (AZ-104) or the now-retired Azure Developer Associate (AZ-204). Since AZ-204 was retired in 2026, AZ-104 is the practical entry route for new candidates.
Microsoft's terms differ from every other provider on this list: exams pass at a scaled 700 out of 1,000, pricing is set by country rather than a single USD figure, and the Expert certification expires annually but renews through a free, open-book online assessment. That makes AZ-400 cheap to maintain but means the true cost of entry includes the AZ-104 exam first. Preparation resources for the exam itself are collected on our AZ-400 Azure DevOps Solutions page.
Candidates deciding between the two most-searched options are usually asking different questions than they realise — one is a tooling credential, the other a platform credential. The comparison:
| Factor | Certified Kubernetes Administrator (CKA) | AWS Certified DevOps Engineer – Professional (DOP-C02) |
|---|---|---|
| Difficulty style | Hands-on tasks under time pressure in live clusters | Long-form multiple choice/response scenario questions |
| Prerequisites | None | None enforced; 2+ years AWS experience recommended |
| Cost (2026 list) | $445 USD, one free retake included | $300 USD, no retake included (50% voucher if you hold an active AWS cert) |
| Validity | 2 years, renewed by full retake | 3 years; also renews two Associate certs |
| Best for | Platform/container-focused roles at any cloud shop | Automation-heavy roles inside AWS environments |
| Career path | → CKS, platform engineering | → AWS specialty certs, senior AWS DevOps roles |
| Skills proven | Cluster operations, troubleshooting, networking, storage | CI/CD on AWS, infrastructure as code, monitoring, incident response |
Neither wins universally. If your target employers run AWS and their listings say "CodePipeline", "CloudFormation" or "AWS DevOps", take DOP-C02. If listings say "Kubernetes" first and the cloud platform second — or you want mobility across employers on different clouds — take the CKA. Engineers with three or more years in AWS-heavy roles frequently end up holding both, and the pairing is stronger than either alone.
HashiCorp Certified: Terraform Associate (004). The best value-per-dollar on this list: a one-hour multiple-choice exam at $70.50 USD plus tax, valid for two years, testing Terraform 1.12. Infrastructure as code appears in a very large share of DevOps listings, and this is the recognised credential for the dominant tool. Make sure any prep material targets version 004, current since January 2026 — the 003 exam is gone. HashiCorp does not publish the passing score. A lab-heavy Professional-tier Terraform certification ($295, four hours, includes a retake) exists for later in your progression.
Google Cloud Professional Cloud DevOps Engineer. The pick for GCP shops: 50–60 questions over two hours, $200 USD plus tax, valid for two years, covering SRE practices, CI/CD pipelines, observability and cost optimisation. Google publishes pass/fail results only and uses no exam codes. Its market is narrower than the AWS and Azure equivalents, so choose it when your target employers are demonstrably on Google Cloud.
GitHub Actions (GH-200). Since July 2025 GitHub exams are delivered through Pearson VUE with Microsoft-style codes; GH-200 is a 100-minute, intermediate, multiple-choice exam at $99 USD in most regions. It is a lightweight but increasingly relevant signal, since GitHub Actions is many teams' entire CI/CD layer. GitLab likewise offers a CI/CD Associate certification for GitLab-based shops — check current details on GitLab's site.
Kubernetes and Cloud Native Associate (KCNA). If the CKA looks premature, this $250 multiple-choice exam (90 minutes, two attempts included, valid two years) is the genuine entry-level Kubernetes credential. It is a stepping stone, not a substitute — treat it as preparation spending, not a CV centrepiece.
A certification list becomes a hiring asset when it tells a coherent story. A pattern that works for most candidates:
Resist adding more than one credential per layer before you have projects demonstrating each. Certificates open interviews; pipelines you have actually built pass them. Our guide on turning a certification into real-world experience covers how to build that evidence, and practice tests along the way are for diagnosing weak domains — analysing which topics you miss and drilling those — never for memorising answers.
Which DevOps certification should a beginner take first?
Start with a cloud Associate-level exam on the platform your target employers use, or KCNA if your gap is specifically Kubernetes. The Tier 1 certifications above assume real hands-on experience; sitting DOP-C02 or the CKA cold wastes money.
Is there an official pass rate for the CKA?
No. Neither CNCF nor the Linux Foundation publishes pass rates, and no provider on this list does. Ignore any source quoting one.
Do these exams include a free retake?
It varies more than people expect: CKA/CKAD/CKS include one retake and Terraform Professional includes one, while AWS, Microsoft and Google Cloud exams include none (Google enforces waiting periods of 14, then 60, then 365 days between failed attempts; Microsoft allows a first retake after 24 hours). Factor retake terms into the real cost of each exam.
How many questions are on the CKA?
The Linux Foundation does not publish a task count. The included killer.sh simulator presents 17 tasks per session, but that is the simulator's count, not the exam's.
Book the certification that removes your biggest credibility gap for the jobs you are actually reading. Missing the platform keyword? Take the relevant cloud exam. Platform covered but no container evidence? The CKA is the strongest single signal in DevOps hiring. Already senior on paper but stuck at mid-level roles? The Professional-tier flagship on your platform is the move. And before you pay any of these fees, run a full-length timed practice test to benchmark yourself — a weak-domain breakdown a month before exam day is worth far more than one the morning after a fail.
