Cloud foundations certs are the lowest-tier credentials each major cloud issues. Azure Fundamentals (AZ-900) and AWS Cloud Practitioner (CLF-C02) are marketed to beginners, non-technical stakeholders, and professionals who need cloud vocabulary without operational depth. They serve real purposes for specific audiences, and they waste time for others. The question of which one to take first (or whether to take either at all) depends on your background and your target next step.
This guide compares AZ-900 and CLF-C02 on exam structure, target audience, preparation time, value to hiring managers, and which makes sense as an entry point in 2026.
Side by Side Comparison
| Attribute | Azure AZ-900 | AWS CLF-C02 |
|---|---|---|
| Full name | Microsoft Certified: Azure Fundamentals | AWS Certified Cloud Practitioner |
| Tier | Fundamentals | Foundational |
| Exam fee (2026) | $99 USD | $100 USD |
| Question count | 40-60 items | 65 items |
| Exam time | 60 minutes | 90 minutes |
| Passing score | 700 / 1000 | 700 / 1000 |
| Format | Multiple choice, drag and drop | Multiple choice, multi-select |
| Prerequisite | None | None |
| Validity | No expiration | 3 years |
| Retake policy | 24 hours after first fail | 14 days |
| Target audience | Business users, new hires, IT beginners | Business users, new hires, IT beginners |
AZ-900 has the unusual property of no expiration. Microsoft treats Fundamentals certs as a permanent entry-level credential. AWS CLF-C02 expires on the standard 3-year cycle.
Target Audience Reality
Both certs are positioned for similar audiences:
- Sales professionals selling cloud services
- Project managers working with cloud-native teams
- New IT hires pre-orientation
- Career switchers who need vocabulary before technical certs
- Business stakeholders approving cloud budgets
Both certs are NOT positioned for:
- Working cloud engineers (go straight to associate tier)
- Developers with any backend experience (skip and start SAA or DVA)
- Systems administrators with hands-on experience (skip and start AZ-104 or SAA)
The most common mistake with either fundamentals cert is taking it when the candidate's actual background justifies skipping it.
"Cloud Practitioner and AZ-900 are vocabulary certs. If you already know what a VM, a load balancer, and a VPC are, you do not need either. If those terms are new, both are reasonable entry points." Adrian Cantrill, cloud training instructor
What AZ-900 Tests
AZ-900 covers high-level Azure concepts. Domain areas:
- Cloud concepts (what is cloud, deployment models, consumption-based pricing)
- Azure architecture and services (regions, availability zones, core compute and storage)
- Management and governance (cost management, policy, RBAC, service level agreements)
Questions are short, definitional, and scenario-light. A typical AZ-900 question asks "Which Azure service provides managed Kubernetes?" or "Which of the following is a characteristic of cloud computing?" Candidates who can define basic cloud terminology pass with minimal prep.
What CLF-C02 Tests
CLF-C02 covers AWS concepts and foundational services. Domain weights for 2026:
| Domain | Weight |
|---|---|
| Cloud Concepts | 24% |
| Security and Compliance | 30% |
| Cloud Technology and Services | 34% |
| Billing, Pricing, and Support | 12% |
CLF-C02 is broader than AZ-900 and slightly deeper. The security and compliance domain at 30 percent is larger than Azure's equivalent weighting. Candidates need to recognize shared responsibility, understand basic IAM concepts, and identify AWS support plan differences.
Preparation Time
AZ-900 Prep
- 1 to 3 weeks at 5 hours per week for candidates with any IT background
- 4 to 6 weeks for candidates new to IT
Study stack: Microsoft Learn AZ-900 learning path (free and sufficient for most candidates), John Savill's AZ-900 crash course (YouTube), Whizlabs practice tests.
CLF-C02 Prep
- 2 to 4 weeks at 5 hours per week for candidates with any IT background
- 5 to 8 weeks for candidates new to IT
Study stack: AWS Skill Builder CLF-C02 course (official and free), Stephane Maarek's Ultimate AWS Certified Cloud Practitioner course, Tutorials Dojo practice tests.
Both are quick-turn certs. Neither requires hands-on lab work, though both benefit from free-tier console familiarity.
Difficulty for Beginners
Community pass rates from Reddit and discussion forums:
| Attempt | AZ-900 | CLF-C02 |
|---|---|---|
| First attempt (no IT background) | ~75% | ~70% |
| First attempt (IT background) | ~90% | ~88% |
| Second attempt | ~92% | ~95% |
Both are beginner-friendly. AZ-900 has slightly higher first-attempt pass rates because its 40-60 question count and 60-minute window reduce fatigue.
Job Market Value
Entry-level cloud job listings that mention either cert as preferred (not required) in Q1 2026:
| Filter | AZ-900 preferred | CLF-C02 preferred |
|---|---|---|
| Entry cloud engineer | ~2,400 | ~5,800 |
| Support engineer | ~1,800 | ~3,500 |
| Sales engineer | ~900 | ~1,400 |
| PM or analyst | ~1,200 | ~2,100 |
CLF-C02 appears more frequently on job listings because the AWS commercial footprint is larger. Neither cert alone typically unlocks roles beyond entry-level or cross-functional positions.
Salary Impact
| Role | AZ-900 holder entry | CLF-C02 holder entry |
|---|---|---|
| Junior cloud support | \(55,000-\)72,000 | \(55,000-\)75,000 |
| IT analyst | \(58,000-\)75,000 | \(60,000-\)78,000 |
| Sales engineer | \(70,000-\)95,000 | \(72,000-\)98,000 |
| PM with cloud team | \(85,000-\)110,000 | \(85,000-\)112,000 |
Salary delta is negligible. Fundamentals certs produce a signaling effect, not a compensation multiplier. Candidates looking for salary uplift should target associate-tier certs (AZ-104, SAA-C03) instead.
"Cloud Practitioner tells hiring managers you cared enough to learn vocabulary. It does not tell them you can configure anything. For an $8,000 salary bump, take SAA. For a vocabulary warm-up, take CLF." Andrew Brown, ExamPro founder
Decision Matrix
Take AZ-900 First If
- Your target cloud employer runs Microsoft 365, Windows Server, Dynamics
- You have zero IT background and need a vocabulary foundation
- Your role is non-technical but cloud-adjacent (PM, analyst, sales)
- You want a credential that does not expire
- You plan to continue to AZ-104 within 6 months
Take CLF-C02 First If
- Your target cloud employer is AWS-first or cloud-native commercial
- You have zero IT background and need a vocabulary foundation
- Your role is non-technical but cloud-adjacent
- You plan to continue to SAA-C03 within 6 months
Skip Both If
- You already work in IT (systems, network, developer, DBA)
- You have passed any other technical certification
- You are comfortable reading AWS or Azure documentation directly
- Your goal is an associate-tier credential and you have 10+ weeks of study time
Value as a Standalone Credential
Neither AZ-900 nor CLF-C02 alone is a career-making credential. Both are stepping stones. The value proposition is:
- Low cost (\(99 to \)100)
- Fast turnaround (2 to 4 weeks for most candidates)
- Confidence build before the bigger cert
- Employer tuition reimbursement unlock (some companies require a pass to approve further training budget)
- Resume line that signals direction
A fundamentals cert on a resume sits alongside (not instead of) associate credentials. Candidates who stop at fundamentals level report marginal hiring impact compared to candidates who continue to associate tier.
Parallel Tracks Neither Cert Addresses
Both AZ-900 and CLF-C02 skip:
- Hands-on configuration (no console work required)
- IAM policy writing
- Networking configuration
- Code deployment patterns
- Cost optimization analysis at depth
- Architecture design
These are associate-tier skills. Candidates who want to do cloud work should plan fundamentals as a 2 to 4 week warm-up, then invest 10 to 16 weeks in associate-tier prep.
Recertification Note
AZ-900 does not expire. CLF-C02 expires after 3 years. The recertification gap matters less than it sounds because most candidates who pass either cert move to associate tier within 12 to 18 months, and the associate cert renewal covers the fundamentals scope implicitly.
| Cert | Expires | Renewal Cost |
|---|---|---|
| AZ-900 | No | N/A |
| CLF-C02 | 3 years | \(50 (discount) or \)0 if upskilled |
Target Audience Edge Cases
Non-Technical Professionals
For PMs, sales, analysts, and procurement specialists, both certs are worth taking. The pass credential on LinkedIn signals cloud literacy to internal stakeholders. Choose based on which cloud your employer primarily uses.
Career Switchers
For candidates switching from non-IT careers (teaching, healthcare, finance administration) into IT, one fundamentals cert plus one associate cert is the minimum for resume credibility.
Experienced IT Pros
For systems admins, network engineers, developers, and DBAs, both certs are skippable. Resume value is minimal, prep time is better spent on associate tier.
Students and Recent Grads
Fundamentals certs are a reasonable final-year-of-college credential. They demonstrate interest and provide a resume line for entry-level applications. Stack with an associate cert within 6 months of graduation.
Cross Domain Considerations
Cloud careers require clear writing even at entry level. Support tickets, handoff notes, and internal updates are daily deliverables. The professional writing templates at Evolang cover structures useful for entry-level IT communication.
Candidates planning future consulting work should start thinking about entity structure early. The business formation guides at Corpy cover LLC and sole proprietor tradeoffs for US professionals.
Deep focus even for short certs requires good study environments. The productivity environment coverage at Down Under Cafe supports study session structure. For spaced-recall on cloud vocabulary, the study protocols at When Notes Fly work well for fundamentals-level memorization.

"The best use of a fundamentals cert is a two-week commitment that confirms your learning instinct for cloud. If you enjoy the AZ-900 material, AZ-104 is next. If you dread it, try cybersecurity or networking instead." Tim Warner, Pluralsight Azure trainer
Quick Decision Framework
- Do you already work in IT? Skip both fundamentals certs.
- Is your target cloud Azure? Take AZ-900.
- Is your target cloud AWS? Take CLF-C02.
- Are you targeting cross-cloud roles? Pick AZ-900 because it does not expire, providing a permanent resume line.
- Budget 2 to 4 weeks, \(99 to \)100, and move on to associate tier.
Common Mistakes
- Over-studying fundamentals. Three weeks is enough for most candidates.
- Stopping at fundamentals level for technical roles. Associate tier is required for technical hiring impact.
- Taking both AZ-900 and CLF-C02 without a specific reason. One fundamentals cert is a warm-up; two is redundant.
- Paying for expensive bootcamps for fundamentals. Microsoft Learn (AZ-900) and AWS Skill Builder (CLF-C02) are free and sufficient.
- Skipping the next step. Fundamentals without associate follow-up is a credential in limbo.
Cost of Ownership Over 5 Years
| Metric | AZ-900 | CLF-C02 |
|---|---|---|
| Initial exam | $99 | $100 |
| Renewal in 5 years | $0 (no expiry) | \(50 (if retaken) or \)0 if upskilled |
| Total 5-year spend | $99 | \(100-\)150 |
Neither cert is expensive to own. The opportunity cost (3 weeks of study time) matters more than the dollar cost.

Frequently Asked Questions
Is AZ-900 or CLF-C02 worth it for someone already working in IT?
Usually no. Both are vocabulary certs aimed at non-technical professionals or career switchers. IT professionals with any hands-on experience should skip both and go directly to associate-tier certs like AZ-104 or SAA-C03 for meaningful career impact.
Does AZ-900 really never expire?
Correct. Microsoft classifies Fundamentals certs as permanent credentials without an expiration date. This differs from AWS, which applies a 3-year validity to CLF-C02. The no-expiration policy makes AZ-900 a one-time investment.
Can I skip fundamentals and go directly to associate tier?
Yes, and most technical candidates do. Associate certs have no prerequisites. Fundamentals certs serve candidates who want a 2 to 4 week confidence-building warm-up before a longer associate-tier prep investment.
Which is easier, AZ-900 or CLF-C02?
AZ-900 is marginally easier based on community pass rates, primarily because its shorter duration and lower question count reduce fatigue. CLF-C02 has slightly more security-domain weight and broader service coverage, making it slightly harder.
Will a fundamentals cert alone get me a cloud job?
Rarely for technical roles. For non-technical cloud-adjacent roles (sales engineer, PM, business analyst), a fundamentals cert paired with relevant prior experience can be sufficient. For engineering roles, associate-tier is the effective minimum.
Should non-technical professionals take both AZ-900 and CLF-C02?
Usually one is enough. Pick the one that matches your employer's primary cloud. Taking both is reasonable for consultants or sales engineers serving multi-cloud clients, but overlapping vocabulary means the second cert adds marginal new knowledge.
How much should I spend on AZ-900 or CLF-C02 prep materials?
Under \(30 total. Microsoft Learn for AZ-900 and AWS Skill Builder for CLF-C02 are both free and sufficient. One third-party practice test set (\)20 to $30) can be a good confidence check before booking the exam.
