AWS Data Center Locations

Answer - C.

AWS has the concept of a Region, which is a physical location around the world where we cluster data centers.

We call each group of logical data centers an Availability Zone.

Each AWS Region consists of multiple, isolated, and physically separate AZ's within a geographic area.

Unlike other cloud providers, who often define a region as a single data center, the multiple AZ design of every AWS Region offers advantages for customers.

The correct answer is C. Region.

Explanation: In AWS, a region is a physical location around the world where data centers are located. Each region is completely independent and contains multiple Availability Zones, which are distinct locations within the region that are engineered to be isolated from failures in other Availability Zones. This allows customers to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.

AWS currently has 25 regions globally, each consisting of multiple availability zones, as of the knowledge cutoff date of September 2021.

Option A, Sub zone, is not a valid term in AWS terminology and does not refer to any particular feature or concept.

Option B, Data center, is a physical facility used to house computer systems and related components, including telecommunications and storage systems. While AWS does operate data centers, the term "data center" does not specifically refer to a physical location with multiple data centers, as in the case of an AWS region.

Option D, Edge location, is a term used to refer to endpoints of the AWS network that are used for caching content. These edge locations are used to accelerate the delivery of content to end users, and are typically located in major cities around the world. While edge locations are a critical part of AWS's infrastructure, they are not synonymous with regions.
