  • pending - The Capacity Reservation request was successful but the capacity provisioning is still pending.

  • targeted - The Capacity Reservation only accepts instances that have matching attributes (instance type, platform, and Availability Zone), and explicitly target the Capacity Reservation. This ensures that only permitted instances can use the reserved capacity.
