3.1.6 Availability Zone

An availability zone is a host-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.

AvailabilityZone adheres to the following requirements:

• AvailabilityZone is RECOMMENDED to be present in a Cost and Usage FOCUS dataset when the host provider supports deploying resources or services within an availability zone.
• AvailabilityZone MUST be of type String.
• AvailabilityZone MUST conform to StringHandling requirements.
• AvailabilityZone MUST be null when a charge is not specific to an availability zone.
