AWS Certified Cloud Practitioner (CRWT) case studies
AWS CRWT · Put your knowledge to work in context.
The AWS Certified Cloud Practitioner is AWS's foundational, vendor-specific cloud credential. It is aimed at people who need a working command of AWS terminology, core services, the shared responsibility model, and the commercial side of cloud adoption - including sales, project management, support, finance, and technical staff early in their cloud journey - rather than at engineers who design and operate workloads daily. The AWS CRWT case studies are 5 cases and about 3,847 words.
