capacityOptionType

The capacity option type. This determines whether Amazon ECS launches On-Demand, Spot or Capacity Reservation Instances for your managed instance capacity provider.

Valid values are:

• ON_DEMAND - Launches standard On-Demand Instances. On-Demand Instances provide predictable pricing and availability.

• SPOT - Launches Spot Instances that use spare Amazon EC2 capacity at reduced cost. Spot Instances can be interrupted by Amazon EC2 with a two-minute notification when the capacity is needed back.

• RESERVED - Launches Instances using Amazon EC2 Capacity Reservations. Capacity Reservations allow you to reserve compute capacity for Amazon EC2 instances in a specific Availability Zone.

The default is On-Demand
