AWS offers 12 certifications across 4 levels, Foundational ($100), Associate ($150), Professional ($300), and Specialty ($300), with no prerequisites required for any exam since 2019, meaning you can take any certification directly once you have the underlying skills.

At full price, earning all 12 certifications costs $2,400. AWS issues a 50% discount voucher for your next exam every time you pass one, valid for 1 year, which drops the realistic chained cost of a full path to roughly $1,350 if you plan your sequence deliberately.
No Prerequisites, But a Recommended Order Still Exists
AWS removed formal prerequisites from every certification in 2019, so nothing stops you from taking DevOps Engineer Professional as your first exam. In practice, almost no one does this successfully, since Professional and Specialty exams assume the working knowledge that Foundational and Associate certifications are built to establish.
| If You Start Here | You’re Likely To Struggle With |
| Cloud Practitioner first | Nothing, this is the intended starting point |
| Solutions Architect Associate with zero AWS experience | Service-specific scenario questions without hands-on context |
| Any Professional exam with no Associate-level experience | Depth and breadth of the exam, these assume real production experience |
| Any Specialty exam outside your working domain | Highly specific technical knowledge the exam assumes you already use daily |
AWS Certification Roadmap by Role
| Target Role | Recommended Path | Total Exam Cost |
| Cloud Generalist / Career Starter | Cloud Practitioner | $100 |
| Solutions Architect | Cloud Practitioner (optional) then Solutions Architect Associate then Solutions Architect Professional | $250 to $550 |
| Application Developer | Cloud Practitioner (optional) then Developer Associate | $150 to $250 |
| Cloud Operations Engineer | Cloud Practitioner (optional) then SysOps Administrator Associate | $150 to $250 |
| DevOps Engineer | Developer or SysOps Associate then DevOps Engineer Professional | $450 |
| Data Engineer | Cloud Practitioner (optional) then Data Engineer Associate | $150 to $250 |
| Machine Learning Engineer | AI Practitioner then ML Engineer Associate then ML Specialty | $350 to $450 |
| Security Engineer | Cloud Practitioner or SysOps Associate then Security Specialty | $250 to $450 |
| Network Engineer | SysOps Administrator Associate then Advanced Networking Specialty | $450 |
Most working cloud professionals hold 2 to 3 AWS certifications at once, not all 12. Pick the row that matches your target role and treat the rest of this catalog as reference material, not a checklist.
Foundational Level: Where Almost Everyone Should Start
| Certification | Best For | Format |
| Cloud Practitioner (CLF-C02) | Anyone new to AWS, including non-technical roles like sales and project management | 65 questions, 90 minutes, $100 |
| AI Practitioner (AIF-C01) | Anyone entering AI or machine learning roles on AWS | 65 questions, 90 minutes, $100 |
Cloud Practitioner requires no technical background and validates broad understanding of AWS services, pricing, and support models. It is not required before Associate-level exams, but most candidates without prior cloud experience find it shortens their Associate-level study time meaningfully.
Associate Level: The Working Professional Tier
| Certification | Best For | Format |
| Solutions Architect Associate (SAA-C03) | Anyone designing AWS infrastructure, the most popular AWS certification overall | 65 questions, 130 minutes, $150 |
| Developer Associate (DVA-C02) | Developers building and deploying applications on AWS | 65 questions, 130 minutes, $150 |
| SysOps Administrator Associate (SOA-C02) | Operations engineers managing and monitoring AWS environments | Performance-based and scenario questions, 130 minutes, $150 |
| Data Engineer Associate (DEA-C01) | Engineers building data pipelines and analytics infrastructure | 65 questions, 130 minutes, $150 |
| Machine Learning Engineer Associate (MLA-C01) | ML practitioners implementing and operating ML solutions on AWS | 65 questions, 130 minutes, $150 |
Solutions Architect Associate remains the single most-earned AWS certification, largely because Solutions Architect skills apply across nearly every cloud career path, not just architecture-titled roles specifically.
Professional Level: Deep, Broad, and Assumes Real Experience
| Certification | Best For | Format |
| Solutions Architect Professional (SAP-C02) | Senior architects designing complex, multi-account AWS environments | 75 questions, 180 minutes, $300 |
| DevOps Engineer Professional (DOP-C02) | Engineers owning CI/CD pipelines and infrastructure automation at scale | 75 questions, 180 minutes, $300 |
Professional exams are widely regarded as the hardest tier in the AWS catalog. They test judgment across ambiguous, multi-service scenarios rather than single-service recall, and most candidates who pass have 2 or more years of hands-on production AWS experience behind them, not just Associate-level study.
Specialty Level: Deep Expertise in One Domain
| Certification | Best For | Format |
| Security Specialty (SCS-C02) | Security engineers responsible for AWS-specific security controls | 65 questions, 170 minutes, $300 |
| Advanced Networking Specialty (ANS-C01) | Network engineers managing complex AWS networking and hybrid connectivity | 65 questions, 170 minutes, $300 |
| Machine Learning Specialty (MLS-C01) | ML practitioners with deep, hands-on modeling and deployment experience | 65 questions, 170 minutes, $300 |
Specialty exams do not build on each other the way Associate leads into Professional. Pick the one that matches your actual domain, since a Machine Learning Specialty holder gets no meaningful advantage studying for Advanced Networking Specialty next.
AWS Certification Salary by Level
| Level | Typical US Salary Range |
| Foundational (Cloud Practitioner) | $70,000 to $95,000 |
| Associate (Solutions Architect, Developer, SysOps) | $95,000 to $135,000 |
| Professional (Solutions Architect Pro, DevOps Pro) | $140,000 to $185,000 |
| Specialty (Security, Networking, ML) | $130,000 to $175,000, ML Specialty trending toward $160,000+ |
Cloud Solutions Architects with Professional-level certification frequently report total compensation between $150,000 and $220,000 in competitive markets, making the Professional tier the strongest single ROI jump in the entire AWS catalog relative to its $300 exam cost. For a detailed breakdown of Solutions Architect compensation specifically by experience level, see our AWS Certification Salary guide.
How to Reduce Your Total AWS Certification Cost
| Strategy | Savings |
| Use the 50% next-exam voucher after every pass | 50% off your next exam, valid 1 year |
| Start with Cloud Practitioner even though it’s optional | Shortens Associate-level study time, reducing indirect cost |
| Use AWS Skill Builder’s free tier | $0 for substantial official prep content |
| Avoid the exam until you consistently score 80%+ on practice tests | Avoids the full-price retake, since AWS offers no retake discount |
There is no discounted retake. If you fail, you pay the full exam fee again, which is the single biggest preventable cost in the entire AWS certification path. For a deeper comparison of the two most contested Solutions Architect-track exams, see our AWS SAA-C03 vs SAP-C02 guide, and if you’re deciding between the architecture and development tracks entirely, see AWS Solutions Architect vs Developer.
Common Mistakes When Planning Your AWS Path
Jumping straight to Professional or Specialty exams without Associate-level production experience. The lack of a formal prerequisite does not mean the exam content assumes beginner knowledge, it assumes real working experience regardless of what AWS technically requires.
Collecting certifications outside your actual career direction. A Developer Associate holder targeting a Solutions Architect role gains more from Solutions Architect Associate next than from an unrelated Specialty exam.
Letting your 50% voucher expire unused. It is valid for exactly 1 year from the date you passed the qualifying exam, and missing that window means paying full price on your next certification.
Assuming Specialty certifications build toward Professional certifications. They don’t. Specialty and Professional are 2 separate, parallel tracks, not sequential steps in the same ladder.
Underestimating Professional-level study time because Associate felt manageable. Professional exams routinely take 2 to 3 times longer to prepare for than Associate exams, even for strong Associate-level candidates.
