The Best DevOps Certifications to Get Hired in 2025
A clear comparison of AWS, Azure, and Kubernetes (CKA) certifications — costs, career impact, and which DevOps course path is right for you.
If you're researching what a DevOps engineer does and how to become one, certifications are one of the fastest ways to prove your skills to employers. In 2025, hiring managers still use credentials as a filter — and the right DevOps course can shortcut months of self-study into a structured, verifiable path.
This guide compares the three most requested DevOps certifications in job postings: AWS Certified DevOps Engineer – Professional, Azure DevOps Engineer Expert, and the Certified Kubernetes Administrator (CKA). We break down cost, difficulty, career impact, and who each cert is best for.
AWS Certified DevOps Engineer – Professional
AWS dominates cloud job postings, and the AWS Certified DevOps Engineer – Professional is the gold standard for cloud-native DevOps roles. It validates your ability to design, deploy, and manage continuous delivery systems on AWS — including IAM, CloudFormation, CodePipeline, and ECS/EKS.
- Cost: ~$300 USD for the exam; prep courses range from $30–$200
- Difficulty: High — AWS recommends 2+ years of hands-on experience
- Career impact: Strong salary bump; frequently required for senior AWS-facing roles
- Best for: Engineers targeting startups or enterprises running on AWS
Azure DevOps Engineer Expert (AZ-400)
Microsoft Azure is the default cloud for many large enterprises, especially in regulated industries. The Azure DevOps Engineer Expert certification (exam AZ-400) proves you can combine people, process, and technology to deliver value continuously through Azure DevOps Services, GitHub Actions, and Azure infrastructure.
- Cost: ~$165 USD for the exam; Microsoft Learn offers free prep paths
- Difficulty: Moderate — broad but less deep than AWS
- Career impact: Excellent for government, finance, and Fortune 500 pipelines
- Best for: Engineers in Microsoft-centric or hybrid-cloud organizations
Certified Kubernetes Administrator (CKA)
Kubernetes is the default container orchestrator, and the CKA from the Cloud Native Computing Foundation (CNCF) is the most respected hands-on credential in the space. Unlike multiple-choice cloud certs, the CKA is a practical exam where you fix and deploy real clusters under time pressure.
- Cost: ~$395 USD; includes one free retake and a killer.sh simulator
- Difficulty: Very high — pure hands-on terminal work with tight timers
- Career impact: Universally respected; opens doors at any company using containers
- Best for: Platform engineers, SREs, and anyone building or maintaining K8s clusters
Quick comparison
| Certification | Cost | Difficulty | Ideal Role |
|---|---|---|---|
| AWS DevOps Pro | ~$300 | High | Senior Cloud / AWS DevOps |
| Azure DevOps Expert | ~$165 | Moderate | Enterprise / Microsoft shops |
| CKA | ~$395 | Very high | Platform / SRE / K8s Engineer |
Which DevOps course should you take first?
Start with the ecosystem you already touch at work or in your lab. If you're building on AWS, pursue the AWS DevOps Pro. If your company is Azure-first, AZ-400 is the logical move. If you want a credential that transfers across any cloud, the CKA is the most portable proof of skill.
Many successful DevOps engineers hold two of these — typically a cloud cert (AWS or Azure) plus the CKA. That combination signals you can both provision infrastructure and orchestrate workloads at scale.
How to prepare without burning out
Set a 90-day study window. Spend the first 30 days on fundamentals through a structured DevOps course, the next 30 on hands-on labs, and the final 30 on practice exams and flashcards. Track your daily progress in the Planner and review weekly in Review.
Certifications alone won't make you a DevOps engineer — but they will get your resume past automated filters and signal to hiring managers that you can operate at a professional level. Pair each cert with real projects from the Projects tracker and you'll be interview-ready faster than you expect.
