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

  • reservations-then-balanced - Auto Scaling will first attempt to launch into your Capacity Reservations, and then balance any remaining capacity across healthy Availability Zones.
