Two ecosystems, one career
At some point during your cloud career you’re going to ask: AWS or Azure? Maybe your company uses one. Maybe you’re freelancing and want to pick the right bet. Maybe you’re already certified in one and wondering if the other is worth the time.
This isn’t a “both are great!” post. They’re different in ways that matter for your time, wallet, and career trajectory. Here’s a direct comparison based on how the certification programs actually work in 2026.
The quick comparison
| AWS | Azure | |
|---|---|---|
| Entry cert | CLF-C02 — $100, 65 questions, 90 min, 700 to pass | AZ-900 — ~$99, 50 questions, 45 min, 700 to pass |
| Top associate cert | SAA-C03 — $150, 65 questions, 130 min, 720 to pass | AZ-104 — $165, 50 questions, 100 min, 700 to pass |
| Cert validity | 3 years | 1 year (renewable free via Microsoft Learn) |
| Retake policy | 14-day wait, unlimited attempts | 24h first, then 14 days, max 5 per year |
| Total certifications | 12 | 31 |
| Study hours (entry) | ~25 hours (CLF-C02) | ~15 hours (AZ-900) |
| Study hours (associate) | ~50 hours (SAA-C03) | ~50 hours (AZ-104) |
Some of these numbers need context. Let’s break them down.
Entry level: CLF-C02 vs AZ-900
Both are fundamentals-level certs. Neither will get you hired on its own. But they serve different purposes.
The AWS Cloud Practitioner (CLF-C02) is a 90-minute exam with 65 questions. Passing score is 700. It costs $100 and is valid for 3 years. You’ll need roughly 25 hours of study time. It covers cloud concepts, security, technology, and billing — broad but shallow.
The Azure Fundamentals (AZ-900) is shorter: 45 minutes, 50 questions, same 700 passing score, ~$99. Most people need about 15 hours to prepare. It covers Cloud Concepts (28%), Azure Architecture and Services (37%), and Azure Management and Governance (35%). Microsoft also occasionally offers free vouchers through events and training days, which knocks the effective cost to zero if you time it right.
The AZ-900 is genuinely easier. Shorter exam, fewer questions, less study time. If you just want to get a cloud cert on your resume fast, it’s the quicker path.
The CLF-C02 goes slightly deeper and has a longer shelf life (3 years vs. 1 year). For the long game, that matters — but you can renew the AZ-900 for free through a Microsoft Learn assessment, so the 1-year validity is less punishing than it sounds.
The honest take: If you’ve never touched cloud and want a confidence boost, AZ-900 is the faster win. If you want the cert that requires no maintenance for three years, CLF-C02.
Associate level: where it actually matters
This is where the comparison gets real, because associate-level certs are what hiring managers actually look for.
AWS Solutions Architect Associate (SAA-C03): 65 questions, 130 minutes, 720 to pass, $150. Four weighted domains — Secure Architectures (30%), Resilient Architectures (26%), High-Performing Architectures (24%), Cost-Optimized Architectures (20%). About 50 hours of prep. Valid for 3 years.
Azure Administrator Associate (AZ-104): 50 questions, 100 minutes, 700 to pass, $165. About 50 hours of prep. Valid for 1 year.
The SAA-C03 is a design exam. It tests whether you can architect solutions. The AZ-104 is an admin exam. It tests whether you can operate Azure environments. They’re not really equivalent — they emphasize different skills. AWS has a separate admin-focused cert (SOA-C03, the SysOps Administrator), while Azure separates the design role into AZ-305 at the expert level.
The study time is comparable. The cost is close. The real difference is what you’re proving: architectural thinking (SAA-C03) vs. operational competence (AZ-104).
The honest take: SAA-C03 is probably the single most recognized cloud certification in the industry. If you’re picking exactly one associate cert and your job doesn’t dictate the platform, that’s the one.
Professional and expert tier
Both platforms have advanced certifications. They’re harder, more expensive, and significantly more respected.
AWS Professional certs (SAP-C02 Solutions Architect Pro, DOP-C02 DevOps Engineer Pro): 750 to pass, $300 each. SAP-C02 is 75 questions in 180 minutes. DOP-C02 is 65 questions in 130 minutes. No formal prerequisites, but you’ll want the associate cert first. These are genuinely difficult exams. Three hours of scenario-based questions with no easy ones.
Azure Expert certs (AZ-305 Azure Solutions Architect Expert): 50 questions, 100 minutes, 700 to pass. Requires AZ-104 as a prerequisite — you can’t skip ahead. Microsoft is more rigid about the path. AWS technically lets you take the professional exam without the associate, though almost nobody does.
The prerequisite structure matters. On AWS, you could theoretically jump straight to SAP-C02 if you’re confident. On Azure, you must hold AZ-104 before you can attempt AZ-305. Microsoft gates the path. AWS doesn’t.
Validity and renewal: the big difference
This is where the two programs diverge sharply, and it’s the thing most comparison articles gloss over.
AWS: 3 years, full stop. Every AWS cert is valid for 3 years. When it expires, you retake the exam. Full exam, full price. There’s no shortcut.
Azure: 1 year, renewable for free. Role-based Azure certs expire after 1 year. But you can renew them by passing a free assessment on Microsoft Learn — no proctoring, no test center, no fee. It takes about 45 minutes and you can do it from your couch.
These are genuinely different philosophies. AWS says: prove you still know this every three years by sitting a full exam. Microsoft says: prove you’re staying current every year through a lightweight assessment.
Which is better depends on how you think about maintenance. If you hate ongoing obligations, the 3-year AWS cycle means you can forget about it for a while. If you don’t want to pay $150-$300 every three years to re-certify, Azure’s free renewal is appealing.
Over six years, renewing an Azure cert costs $0 (assuming you pass the free assessments). Renewing an AWS cert costs $150-$300 for a second full exam. Over a career, this adds up.
The retake math
If you fail, the policies differ.
AWS: Wait 14 days, then try again. No limit on attempts. Every retake costs the full exam fee.
Azure: First retake after 24 hours. Then 14 days between subsequent attempts. Maximum 5 attempts in any 12-month period. If you fail 5 times in a year, you’re locked out until the clock resets.
The 24-hour turnaround on the first Azure retake is genuinely helpful. If you fail by a few points and the material is fresh, you can go again the next day.
The catalog question
AWS has 12 certifications. Azure has 31.
That’s not because Azure covers more territory — it’s because Microsoft slices the pie thinner. Azure has separate certs for AI Engineer, Data Engineer, Data Scientist, Database Administrator, and more. AWS bundles those into fewer, broader certifications.
More options can be good (you pick exactly what matches your role) or bad (the choices are overwhelming and some niche certs don’t register with hiring managers).
So which one?
Here’s the straightforward answer:
If your company uses Azure, get Azure certs. Nothing else makes sense. The knowledge transfers directly to your daily work, your employer may pay for the exams, and you’ll see immediate ROI.
If your company uses AWS, get AWS certs. Same logic.
If you’re freelancing or job-hunting and don’t have a platform commitment, AWS still has more overall market share. The SAA-C03 is the most widely-recognized cloud cert in existence. It’s a safe default.
But Azure is growing faster in enterprise. If you’re targeting large enterprises, government, or organizations that run Microsoft 365 and Windows Server, Azure certs carry more weight than AWS in those conversations.
The multi-cloud move: Some people get both. Start with whichever matches your current role, then add the other platform’s fundamentals cert. CLF-C02 + AZ-900 together takes about 40 hours of study and costs under $300. That combination signals versatility without requiring months of study.
Preparing for either
Both platforms test the same fundamental skill: can you reason about cloud architecture under time pressure? The specific services differ, but the thinking is the same — availability, security, cost, performance.
If you want to know where you stand before booking either exam, per-domain readiness scoring shows you exactly which areas need work. Whether you’re targeting your first cloud cert or adding a second platform to your resume, the prep approach matters more than the platform choice.
Pass-IT covers both — all 12 AWS certs, all 31 Azure certs, plus Google Cloud. Pick the exam that matches your career, then build a study plan that actually measures readiness instead of counting hours.
