The AWS Cloud operates in 16 geographic Regions with 44 Availability Zones around the world.
For more details, visit: https://aws.amazon.com/about-aws/global-infrastructure/.
A region is a location in any part of the world while Availability Zones (AZs) are separate data centers available in a specific region.
Each region is isolated from another region, and each Availability Zone is planned as an independent failure zone to support highly Available Resources, Fault-Tolerant Resources, and Scalable Application Architecture.
