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.
Availability zones play an essential role in how subnets are used in a VPC.
An auto-scaling group can span multiple availability zones.

API
The only way to access AWS resources is via API calls: the AWS management console, AWS CLI and custom applications that are using various SDKs all interact via resources in the same way.
Signing API Calls
All API calls are signed for authentication and authorization with a user's API access key.
