Description
An availability zone is a provider-assigned identifier for a physically separated and isolated area within a Region that provides high availability and fault tolerance. Availability Zone is commonly used for scenarios like analyzing cross-zone data transfer usage and the corresponding cost based on where resources are deployed.
The AvailabilityZone column is RECOMMENDED to be present in the billing data when the provider supports deploying resources or services within an availability zone. This column MUST be of type String and MAY contain null values when a charge is not specific to an availability zone.
