Quick answer: Choose AZ-900 if your organization or target employers use Microsoft Azure, or if you work in a Microsoft-centric environment. Choose AWS Cloud Practitioner (CLF-C02) if you’re in a startup, consulting role, or plan to work with AWS-first companies. Both are entry-level, vendor-specific certifications that validate foundational cloud knowledge, but they differ in difficulty, study time, and career impact.
Why Compare These Two Certifications?
The AZ-900 (Microsoft Azure Fundamentals) and AWS Cloud Practitioner (CLF-C02) are the most popular entry-level cloud certifications on the market. Both require no prior cloud experience and serve as a starting point for cloud careers. However, they are not interchangeable—each aligns with a different ecosystem, job market, and career trajectory.
If you’re deciding between them, you’re likely asking: Which one gives me the best return on time and effort? This guide breaks down each factor so you can make an informed choice without wasting weeks on the wrong exam.
Difficulty and Study Time
Both exams are designed for beginners, but they differ in scope and depth.
- AZ-900 covers Azure core concepts, pricing models, SLAs, compliance, and basic cloud principles. It’s conceptual—you won’t need to configure VMs or storage accounts. Most candidates pass with 20–30 hours of study.
- AWS Cloud Practitioner (CLF-C02) covers AWS global infrastructure, billing, security, and basic services like EC2, S3, and IAM. It’s slightly broader because AWS has more services. Expect 25–40 hours of study.
Verdict: AZ-900 is marginally easier due to narrower scope. Both are passable with focused effort.
Salary Impact and Job Market Demand
Neither certification alone guarantees a salary bump, but they can open doors to entry-level roles.
- AZ-900 is often required for Microsoft partner roles or government contracts. Average salary for Azure entry-level roles (e.g., Azure Administrator) is $70k–$90k in the US. Azure skills are in high demand in enterprises migrating from on-premises.
- AWS Cloud Practitioner is more recognized in startups and tech-first companies. AWS holds ~32% of the cloud market (vs Azure’s ~23%). Entry-level AWS roles (e.g., Cloud Support Associate) pay $65k–$85k on average.
Verdict: AWS has a larger job market, but Azure roles often pay slightly more due to enterprise budgets. Both are strong.
Career Paths After Certification
Your first cert shapes your learning path. Here’s what follows each:
- After AZ-900: Azure Administrator (AZ-104) → Azure Solutions Architect (AZ-305) or Azure DevOps Engineer (AZ-400). Focuses on Microsoft stack (Active Directory, SQL Server, .NET).
- After AWS Cloud Practitioner: AWS Solutions Architect (SAA-C03) → AWS DevOps Engineer (DOP-C02) or AWS Security Specialty. Focuses on Linux, Python/Node.js, and open-source tools.
Verdict: Choose based on your preferred ecosystem. Azure ties you to Microsoft; AWS ties you to a broader open-source world.
Recommendation Matrix
Use this simple decision guide:
| Your Situation | Recommended Cert | Why |
|---|---|---|
| Company uses Azure, Office 365, or Active Directory | AZ-900 | Direct alignment with existing tools |
| Company uses AWS or is cloud-native | CLF-C02 | Immediate relevance to daily work |
| You’re a sysadmin transitioning to cloud | AZ-900 (if on Windows) or CLF-C02 (if on Linux) | Matches your OS familiarity |
| You’re a student or career changer | CLF-C02 | AWS has more free training and broader job listings |
| You want to work at a startup | CLF-C02 | Startups overwhelmingly use AWS |
| You want to work at a large enterprise or government | AZ-900 | Azure dominates these sectors |
| You’re undecided or want maximum flexibility | Both | Start with one, then the other—they complement each other |
Exam Format and Cost
- AZ-900: 40–60 questions, 85 minutes, $99 USD. Pass mark: 700/1000. Online or in-person.
- CLF-C02: 65 questions, 90 minutes, $100 USD. Pass mark: 700/1000. Online or in-person.
Both offer free practice tests and official learning paths. AZ-900 has a slightly higher pass rate (~70% vs ~65% for CLF-C02) due to simpler content.
Which One Should You Take First?
If you’re still unsure, consider your next certification. The AZ-900 leads to Azure-specific roles, while CLF-C02 leads to AWS-specific roles. Neither is “better” universally—your decision should be based on your target job market.
For most people starting out: AWS Cloud Practitioner is the safer bet because AWS has a larger market share and more entry-level job postings. However, if you work in a Microsoft-heavy environment (e.g., healthcare, finance, government), start with AZ-900.
Final Takeaway
Both certifications are valuable, but they are not interchangeable. Choose AZ-900 if Azure aligns with your career goals; choose CLF-C02 if AWS does. If you’re still unsure, start with AWS Cloud Practitioner—it’s the more versatile entry point.
