Why each option
The AWS Cloud global infrastructure is composed of AWS Regions, which are geographically isolated areas, and Availability Zones, which are isolated locations within a Region.
Availability Zones are distinct locations within an AWS Region that are engineered to be isolated from failures in other Availability Zones. They provide high availability and fault tolerance for applications.
Amazon ElastiCache is a managed in-memory data store service, not a component of the global infrastructure.
AWS Regions are physical locations around the world where AWS clusters data centers. Each Region consists of multiple, isolated, and physically separate Availability Zones.
Amazon S3 is an object storage service, not a foundational component of the global infrastructure, although it utilizes the infrastructure.
Amazon VPC is a virtual network dedicated to an AWS account within an AWS Region, not a foundational global infrastructure component itself.
