Many different services are available in the scope of AWS; however, they roughly fall under the two major categories—foundation and platform services. Whereas the platform services completely comply with the PaaS model, the foundation services are an expansion of the basic IaaS with some platform and serverless solutions. Additionally, AWS offers many services for management, deployment, and monitoring of applications.
AWS foundational services can be functionally divided into the following groups:
Network services
Compute services
Storage services
Security and identity services
End-user applications
