availabilityZoneRebalancing

Indicates whether to use Availability Zone rebalancing for the service.

For more information, see Balancing an Amazon ECS service across Availability Zones in the Amazon Elastic Container Service Developer Guide.

The default behavior of AvailabilityZoneRebalancing differs between create and update requests:

• For create service requests, when no value is specified for AvailabilityZoneRebalancing, Amazon ECS defaults the value to ENABLED.

• For update service requests, when no value is specified for AvailabilityZoneRebalancing, Amazon ECS defaults to the existing service’s AvailabilityZoneRebalancing value. If the service never had an AvailabilityZoneRebalancing value set, Amazon ECS treats this as DISABLED.
