Amazon Web Services
Cloud Practitioner, Solutions Architect, Developer & more
Official certification pageAbout AWS
Amazon Web Services launched its certification program in 2013, establishing one of the most recognized cloud credential paths in the industry. The program spans Cloud Practitioner, Developer, DevOps, Solutions Architect, SysOps, and a growing set of specialty certifications covering AI/ML, security, advanced networking, and data engineering.
Why get certified
AWS holds over 31% of the global cloud market, making these credentials directly applicable at more employers than any other cloud platform. Certified professionals consistently report salary premiums of 20–26% over non-certified peers, and AWS certs are listed as requirements or preferences in more cloud job postings than any other vendor.
AWS Certification Practice Exams
AWS organizes its certifications into Foundational, Business, Associate, Professional, and Specialty categories. The new Business category includes AI Business Strategist (AIB-C01), which tests strategic decision-making rather than hands-on implementation. The center of gravity in 2026 is AI: AWS now offers AI Practitioner, AI Business Strategist, Machine Learning Engineer Associate, and Generative AI Developer Professional paths for different roles.
Exam fees scale by category: standard Business and Foundational exams cost 100 USD, Associate exams cost 150 USD, and Professional and Specialty exams cost 300 USD. Beta pricing is lower: AIB-C01 is currently 50 USD and MLA-C02 is 75 USD. Every AWS certification is valid for 3 years, and there are no formal prerequisites, so candidates can enter at the category that matches their role and experience.
CertCompanion carries 16 AWS practice banks, including 341 AIB-C01 questions and 321 MLA-C02 questions. The catalog also covers Cloud Practitioner and AI Practitioner; Solutions Architect, Developer, Data Engineer, Machine Learning Engineer, and CloudOps at Associate; Solutions Architect, DevOps Engineer, and Generative AI Developer at Professional; and the Security, Advanced Networking, and legacy Machine Learning Specialty tracks. Every exam includes 30 free questions, so you can gauge difficulty before committing to a bank.
If you are planning a 2026 attempt, mind the transition calendar. MLA-C01 has its final English sitting on September 28, 2026, and MLA-C02 beta delivery begins September 29; AWS has not yet announced MLA-C02's general-availability date. The AIB-C01 beta is also currently bookable. Always check the live AWS exam page before scheduling because beta formats, language availability, and transition dates can change.
