Which definition best describes AWS Regions?

"Separate, isolated geographic areas that contain availability zones"

AWS region is a geographic area where AWS has established data centers, known as Availability Zones. Each AWS region is designed to be isolated from other regions to provide fault tolerance and stability.

Popular AWS regions include but are not limited to regions in North America (e.g., us-east-1, us-west-2), Europe (e.g., eu-west-1), Asia-Pacific (e.g., ap-southeast-1), and more.

When deploying resources on AWS, users can choose the region that best aligns with their specific requirements, taking into consideration factors such as latency, compliance, and service availability. The selection of the right region is an essential aspect of designing a well-architected and efficient AWS infrastructure.
