Information about an instance type to use in a Capacity Reservation Fleet.

Attributes

availability_zone class-attribute instance-attribute
availability_zone: str | None = ...

The Availability Zone in which the Capacity Reservation Fleet reserves the capacity. A Capacity Reservation Fleet can't span Availability Zones. All instance type specifications that you specify for the Fleet must use the same Availability Zone.

availability_zone_id class-attribute instance-attribute
availability_zone_id: str | None = ...

The ID of the Availability Zone in which the Capacity Reservation Fleet reserves the capacity. A Capacity Reservation Fleet can't span Availability Zones. All instance type specifications that you specify for the Fleet must use the same Availability Zone.

ebs_optimized class-attribute instance-attribute
ebs_optimized: bool | None = ...

Indicates whether the Capacity Reservation Fleet supports EBS-optimized instances types. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using EBS-optimized instance types.

instance_platform class-attribute instance-attribute
instance_platform: str | None = ...

The type of operating system for which the Capacity Reservation Fleet reserves capacity.

instance_type class-attribute instance-attribute
instance_type: str | None = ...

The instance type for which the Capacity Reservation Fleet reserves capacity.

priority class-attribute instance-attribute
priority: int | None = ...

The priority to assign to the instance type. This value is used to determine which of the instance types specified for the Fleet should be prioritized for use. A lower value indicates a high priority. For more information, see Instance type priority in the Amazon EC2 User Guide.

weight class-attribute instance-attribute
weight: float | None = ...

The number of capacity units provided by the specified instance type. This value, together with the total target capacity that you specify for the Fleet determine the number of instances for which the Fleet reserves capacity. Both values are based on units that make sense for your workload. For more information, see Total target capacity in the Amazon EC2 User Guide.
