AWS DevOps vs Azure DevOps Certification

What each exam actually certifies

Read the two blueprints side by side and the family resemblance is obvious — both certify the automation of software delivery and operations, and both expect fluency in infrastructure as code, release engineering and monitoring. The divergence is ecosystem framing.

AZ-400's blueprint is notable for how much of it is not Azure-branded: GitHub features prominently throughout the pipeline and source-control domains, reflecting GitHub's position inside Microsoft. If your organisation hosts code on GitHub — regardless of where it deploys — the AZ-400 syllabus overlaps your daily work more than its name suggests. It is also worth knowing that GitHub's own certification exams moved to Microsoft-style delivery in 2025 (GitHub Foundations is GH-900, GitHub Actions GH-200), making them cheap, natural warm-ups for AZ-400's pipeline content.

DOP-C02 certifies the same discipline expressed entirely in AWS services, at the depth AWS reserves for its Professional tier — AWS's own framing is engineers who provision, operate and manage AWS environments with automation. Consult the official DOP-C02 exam guide for the current domain list rather than third-party summaries; AWS updates guides between full version changes.

Both platforms leave a shared toolbox uncertified: Kubernetes, Terraform and similar cross-platform tools have their own credentials (CKA, Terraform Associate) that travel with you across employers, whichever cloud badge you choose.

Total cost over three years, not just the exam fee

Sticker prices mislead here, because validity and renewal rules differ sharply.

• AWS route: $300 for DOP-C02 (regional pricing varies), valid three years. Renewal means retaking the current professional exam — though active AWS cert holders get a 50% discount voucher towards their next exam, which softens both the initial climb (if you hold an Associate cert) and recertification. Budget for the retake cycle as a real recurring cost.
• Azure route: two exams to enter — AZ-104 plus AZ-400, each priced by country (Microsoft prints no flat USD figure; associate/expert exams are commonly cited around US$165 by third parties, but treat that as unofficial). After that, renewal is where Microsoft wins outright: role-based certifications expire after one year but renew free through an online, unproctored, open-book assessment on Microsoft Learn, retakeable without limit within the renewal window. Held for six years, the Azure credential's exam spend is front-loaded and then effectively zero; the AWS credential bills you again every third year.

If you fail either provider's exam, retakes are permitted after a waiting period (24 hours for a first Microsoft retake, with longer waits later; AWS retakes follow its published policy) — but every attempt is a fresh fee, unlike Kubernetes-style exams that bundle a free retake.

Market demand: what the numbers support

Both credentials target the same well-paid role family. US salary aggregators put DevOps engineer pay in six figures on average — Glassdoor showed roughly $145,000 average total pay and Indeed about $134,000 as of August 2026 — with the usual caveat that pay varies widely by location, experience and employer, and no figure is specific to either certification.

On platform footprint, Synergy Research Group's Q3 2025 data puts AWS at 29% of the cloud infrastructure market, Microsoft at 20% and Google at 13%, with AWS's share drifting down from around 32% in 2021 while Microsoft and Google gained. Read practically: AWS-skilled DevOps engineers face the largest pool of employers; Azure-skilled ones face a large and growing pool, weighted towards enterprises standardised on Microsoft. AWS also reported over 1.42 million active certifications as of January 2025 — recognition for its credentials is not in question, but neither is competition among holders.

Two engineers, two right answers

Scenario one: a platform engineer with three years running EKS clusters and Terraform on AWS, whose employer has no Azure footprint. DOP-C02 is the obvious move — no prerequisite detour, direct validation of daily work, and the professional tier signals seniority in the ecosystem where this engineer's next three job applications will land.

Scenario two: a .NET developer at an enterprise that hosts code on GitHub, deploys to Azure and manages identity through Entra. The AZ-104 → AZ-400 staircase costs an extra exam but produces two credentials aligned to the actual estate — and the annual free renewal keeps both current with negligible ongoing cost. Sitting DOP-C02 instead would certify a platform this developer never touches.

The genuinely torn candidate — no platform commitment, choosing a lane from scratch — is really asking a platform question, not a certification question; that decision framework lives in Azure vs AWS for DevOps careers.

How to prepare for whichever you choose

1. Download the official exam guide (AWS) or study guide (Microsoft, aka.ms study-guide links on the exam page) and audit yourself honestly against each skill area.
2. Close gaps with hands-on work, not videos — both exams punish candidates who have read about pipelines but never debugged one.
3. Use the provider's free assets: AWS Skill Builder question sets for DOP-C02; Microsoft Learn's free practice assessment and exam sandbox for AZ-400.
4. Finish with timed, full-length practice to expose weak domains and build stamina for the scenario-question format. ExamPractice has question sets for both exams — AWS DevOps Engineer Professional DOP-C02 practice questions and AZ-400 practice questions — with free samples on each page and a timed simulation mode for subscribers. Analyse the results by domain and restudy the weak ones; memorising answers defeats the purpose and does not survive contact with either exam's scenario style.

Mistakes candidates make choosing between these two

• Booking DOP-C02 as a first AWS exam. It is permitted — AWS has no prerequisites — but the professional tier assumes fluency that most engineers build through associate-level work first. If you have never sat an AWS exam, an Associate cert first also earns the 50% voucher that discounts the professional attempt.
• Treating the AZ-104 prerequisite as a formality. It is a full associate exam covering identity, storage, compute, networking and monitoring. Developers who schedule AZ-400 for "next month" without an Azure administration background usually discover the staircase is real.
• Comparing sticker prices instead of lifecycle costs. A three-year view — AWS retakes versus Microsoft's free annual renewal — changes the arithmetic materially, as covered above.
• Studying to a course instead of the current blueprint. Both providers revise exams: Microsoft retired an entire prerequisite route (AZ-204) in 2026, and AWS refreshes exam guides between version changes. Always start from the official guide dated this year.
• Assuming the certification substitutes for platform choice. If you are undecided on the platform itself, deciding that first — on job-market evidence, not exam preference — makes this comparison trivial.

Frequently asked questions

Can I take AZ-400 before AZ-104?

You can sit the exams in either order, but the DevOps Engineer Expert certification is only awarded once you hold Azure Administrator Associate. Most candidates take AZ-104 first because its content underpins AZ-400 anyway.

Is DOP-C02 harder than AZ-400?

As a single sitting, most candidates find DOP-C02 the tougher exam — 75 scenario questions over three hours at AWS's highest role tier. But the Azure credential requires passing two exams, so total effort is closer than single-exam difficulty suggests. No official pass rates exist for either.

Do these certifications expire at the same rate?

No. AWS certifications last three years and renew by retake; Microsoft role-based certifications last one year but renew free via an online open-book assessment.

Does either certification require the other provider's knowledge?

No. Each is platform-specific. Cross-platform DevOps tools are better evidenced by separate credentials such as the Certified Kubernetes Administrator or HashiCorp's Terraform Associate.

Is there a Google equivalent?

Yes — the Google Professional Cloud DevOps Engineer ($200, valid two years). It belongs in a three-way comparison of provider tracks; see AWS vs Azure vs Google Cloud certification.

The deciding question to ask yourself

Strip away the exam trivia and one question settles this: where will your pipelines run for the next three years? Certify the platform you will actually operate. If that is AWS, book DOP-C02 and respect its three-hour scenario format. If it is Azure or a GitHub-centred shop, accept the AZ-104 staircase and bank the free annual renewals. And if you cannot answer the question yet, resolve the platform choice first — the certification choice then makes itself.
