An ''availability zone'' is a distinct location within a [[#Region|region]] engineered to be isolated from failures in other availability zones. Think about it as ''location'': by placing resources in different availability zones you can protect the application from the failure of a single location.

Availability Zones
An availability zone is a distinct location within a region engineered to be isolated from failures in other availability zones. Think about it as location: by placing resources in different availability zones you can protect the application from the failure of a single location. Each region provides low-latency network connectivity with other zones within the same region. Example of availability zones within a region: us-west-2b.
