Answer: Region

## Explanation In AWS, **Regions** correspond to different geographic locations around the world. Each AWS Region is a separate geographic area that contains multiple, isolated locations known as Availability Zones. ### Key Differences: - **Region**: A geographic area containing multiple Availability Zones (e.g., us-east-1, eu-west-1) - **Availability Zone**: One or more discrete data centers within a Region with redundant power, networking, and connectivity - **Data center**: Physical facility housing computing infrastructure within an Availability Zone - **Edge location**: Points of presence used by AWS services like CloudFront for content delivery Regions are designed to be completely isolated from one another to provide fault tolerance and stability. When you need to deploy resources in different geographic locations for disaster recovery or to serve users in different parts of the world, you would use different AWS Regions.
