Azure vs AWS: Which Cloud Certification Should You Start With?

You're standing at the edge of the cloud world and you're not sure which way to walk. Azure? AWS? The two giants look the same from far away — both sell computing power, storage, and networking over the internet. But the certifications that introduce them, Microsoft's AZ-900 and AWS's CLF-C02, take you down genuinely different paths.

This guide breaks down what each exam actually covers, how hard they are, what the job market looks like, and — most importantly — which one fits *your* situation.

What Each Certification Covers

AZ-900: Microsoft Azure Fundamentals is Microsoft's entry point into its cloud. The exam covers three big areas:

• Cloud concepts (25–30%): What cloud computing is, the difference between public, private, and hybrid cloud, and how Azure's pay-as-you-go model works.
• Azure services (40–45%): The core products — virtual machines, Azure App Service, Azure Functions, storage accounts, virtual networks, Azure SQL Database, and a tour of the AI and IoT services.
• Management and governance (25–30%): Cost management tools, resource groups, Azure Policy, role-based access control, and Microsoft's privacy and compliance framework.

CLF-C02: AWS Certified Cloud Practitioner is Amazon's equivalent. Its four domains:

• Cloud concepts (24%): Cloud models, AWS's global infrastructure (Regions, Availability Zones, edge locations), and how you pay for services.
• Security and compliance (30%): The shared responsibility model, IAM basics, encryption, and compliance programs. This domain is bigger than AZ-900's security section — AWS wants you to think "security first" from day one.
• Technology (34%): The core services — EC2, S3, Lambda, RDS, VPC, Route 53 — plus how to deploy and manage them through the console and other tools.
• Billing and pricing (12%): The AWS Pricing Calculator, Cost Explorer, AWS Budgets, and support plans.

Notice the overlap: both teach cloud concepts, core services, security basics, and pricing. The difference isn't *what* they teach so much as *whose vocabulary* they teach it in. Passing either one means you understand the cloud. Passing one makes the second much easier.

Difficulty: How Hard Is Each Exam?

Let's be honest: both are fundamentals exams, and neither expects you to actually *do* anything hands-on. You're not configuring virtual networks or deploying servers. You're answering multiple-choice questions about concepts, service names, and use cases.

That said, most people find CLF-C02 slightly harder than AZ-900. Here's why:

• CLF-C02 has more services to memorize. AWS's product catalog is enormous, and the exam expects you to know more of it — EC2 instance types, S3 storage classes, the difference between RDS and DynamoDB, and so on.
• AWS naming is less intuitive. Azure names things like "Virtual Machines" and "Storage Accounts" — you can guess what they do. AWS names things like "EC2," "S3," "CloudFormation," and "Elastic Beanstalk." Nothing about those names tells you what they are, so you're memorizing from scratch.
• CLF-C02 has 65 questions in 90 minutes. AZ-900 has 40–60 questions in 45 minutes. The time pressure is comparable, but the AWS exam packs in more questions.

AZ-900 isn't *easy*, exactly. Microsoft loves testing governance and compliance topics — Azure Policy, management groups, service-level agreements — that beginners find dry and hard to keep straight. But if you've used any Microsoft product in an office, the terminology feels familiar. That counts for a lot when you're studying.

Bottom line: both are very passable for a motivated beginner. Expect to spend 2–4 weeks studying for either one, part-time. If you're starting from zero IT background, give yourself a full month.

The Job Market: Which One Do Employers Want?

Here's where things get interesting, because the answer is "both" — but not equally everywhere.

AWS is still the market leader. It holds roughly a third of the cloud market, and job postings reflect that. If you search for "cloud" jobs on any major board, AWS skills show up in more listings than Azure. Startups, tech companies, and digital-native businesses run on AWS far more often than Azure.

Azure is the enterprise king. Walk into any large company that already runs Windows servers, Active Directory, and Office 365 — and there are a *lot* of them — and you'll find Azure. Microsoft's pitch is simple: you already trust us for your desktops and email, so let us run your cloud too. That argument works. Azure has been gaining ground steadily, and in some regions and industries (government, healthcare, finance), it's the default.

For an entry-level person with just a fundamentals cert, neither one gets you a job on its own. These certs don't qualify you to *be* a cloud engineer — they qualify you to *start talking* about cloud like you know what you're doing, which is exactly what you need for help desk roles, junior admin positions, and IT support jobs where the company is moving to the cloud.

Who Should Pick Azure (AZ-900)?

Start with AZ-900 if:

• You work (or want to work) in an enterprise environment. If the companies around you run Windows, use Active Directory, and live in Microsoft 365, Azure is the cloud they'll move to. Your AZ-900 knowledge plugs directly into that world.
• You're aiming for a Microsoft-heavy career path. Azure Administrator (AZ-104), Azure Security Engineer (AZ-500), and Azure Solutions Architect (AZ-305) all build on AZ-900. If that ladder appeals to you, start at the bottom of it.
• You prefer intuitive naming and Microsoft's ecosystem. If you've administered Windows servers or managed Office 365, the learning curve is gentler. The concepts will feel like extensions of things you already know.
• You want the slightly easier first win. There's no shame in this. Passing AZ-900 first gives you confidence, a credential, and a foundation that makes CLF-C02 easier later.

Who Should Pick AWS (CLF-C02)?

Start with CLF-C02 if:

• You want maximum job-board visibility. More listings mention AWS than any other cloud. If you're job hunting without a specific employer in mind, AWS gives you the broadest coverage.
• You're drawn to startups and tech companies. The startup world runs on AWS. If you want to work at a tech company rather than an enterprise IT department, AWS is the safer bet.
• You plan to go deeper into cloud engineering. AWS Solutions Architect Associate (SAA-C03) is one of the most respected associate-level certs in the industry, and CLF-C02 is its direct on-ramp.
• You want the harder fundamentals exam out of the way first. Some people prefer to tackle the bigger challenge first and coast on the easier one later. If that's your style, start with AWS.

Can You Do Both?

Yes — and eventually, you probably should. Here's the thing most beginners don't realize: the second cloud cert is dramatically easier than the first. Cloud concepts transfer almost perfectly. A virtual machine is a virtual machine whether Microsoft or Amazon sells it. Load balancing, auto-scaling, serverless functions, object storage — the ideas are the same, only the names change.

A common path is to earn one fundamentals cert, work with that cloud for a few months (even just the free tier), and then pick up the other one in a couple of weeks of study. Having both on your resume tells employers you're not locked into one vendor's way of thinking — and in a multi-cloud world, that's increasingly what companies want.

If you do both, the order barely matters. Pick the one that matches your first job target, get it, and circle back for the other one when you have time.

Study Path Recommendations

For AZ-900:

1. Start with Microsoft Learn's free AZ-900 learning path. It's genuinely good and it's free.
2. Focus extra time on governance — Azure Policy, management groups, resource locks, SLAs. This is where beginners lose the most points.
3. Drill service names and their use cases with practice questions until the names feel automatic.

For CLF-C02:

1. Start with AWS Skill Builder's free Cloud Practitioner Essentials course.
2. Make flashcards (or use practice tests) for the service catalog. The sheer number of AWS service names is the biggest hurdle.
3. Spend real time on the shared responsibility model and IAM basics — security is the biggest domain and AWS tests it hard.
4. Use the AWS free tier to click around the console. Seeing EC2 and S3 in the actual console makes the exam questions far less abstract.

For both: take timed practice exams under real conditions. Fundamentals exams are won and lost on recall speed and reading comprehension — you need to be comfortable with the question style before exam day.

Ready to Start?

Whichever cloud you pick, the exam itself is the same kind of challenge: dozens of multiple-choice questions testing whether you *know* the services, the concepts, and the pricing models. The best way to prepare is to test yourself relentlessly until the material feels boring — because boring means you know it.

That's exactly what CertCrack's practice exams are built for. Our AZ-900 practice exam packs 700 original questions covering every exam domain, and our CLF-C02 practice exam does the same with 865 questions — all with clear explanations for every answer, timed like the real thing, with an 80% pass mark so you know you're ready before you pay for the real exam.

Pick your cloud, start practicing, and walk into exam day ready.
