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 a FOCUS dataset 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.
