capacityDistributionStrategy

If launches fail in an Availability Zone, the following strategies are available. The default is balanced-best-effort.

• balanced-only - If launches fail in an Availability Zone, Auto Scaling will continue to attempt to launch in the unhealthy zone to preserve a balanced distribution.

• balanced-best-effort - If launches fail in an Availability Zone, Auto Scaling will attempt to launch in another healthy Availability Zone instead.
