The minimum and maximum total accelerator memory in mebibytes (MiB). This is important for GPU workloads that require specific amounts of video memory.

Type: AcceleratorTotalMemoryMiBRequest object

Required: No

The accelerator types to include. You can specify gpu for graphics processing units, fpga for field programmable gate arrays, or inference for machine learning inference accelerators.

Type: Array of strings

Valid Values: gpu | fpga | inference

Required: No

The instance types to include in the selection. When specified, Amazon ECS only considers these instance types, subject to the other requirements specified.

Type: Array of strings

Array Members: Maximum number of 400 items.

Length Constraints: Minimum length of 1. Maximum length of 30.

Pattern: [a-zA-Z0-9\.\*\-]+

Required: No

Indicates whether to include bare metal instance types. Set to included to allow bare metal instances, excluded to exclude them, or required to use only bare metal instances.

Type: String

Valid Values: included | required | excluded

Required: No

The minimum and maximum baseline Amazon EBS bandwidth in megabits per second (Mbps). This is important for workloads with high storage I/O requirements.

Type: BaselineEbsBandwidthMbpsRequest object

Required: No

Indicates whether to include burstable performance instance types (T2, T3, T3a, T4g). Set to included to allow burstable instances, excluded to exclude them, or required to use only burstable instances.

Type: String

Valid Values: included | required | excluded

Required: No

The CPU manufacturers to include or exclude. You can specify intel, amd, or amazon-web-services to control which CPU types are used for your workloads.

Type: Array of strings

Valid Values: intel | amd | amazon-web-services

Required: No

The instance types to exclude from selection. Use this to prevent Amazon ECS from selecting specific instance types that may not be suitable for your workloads.

Type: Array of strings

Array Members: Maximum number of 400 items.

Length Constraints: Minimum length of 1. Maximum length of 30.

Pattern: [a-zA-Z0-9\.\*\-]+

Required: No

The instance generations to include. You can specify current to use the latest generation instances, or previous to include previous generation instances for cost optimization.

Type: Array of strings

Valid Values: current | previous

Required: No

Indicates whether to include instance types with local storage. Set to included to allow local storage, excluded to exclude it, or required to use only instances with local storage.

Type: String

Valid Values: included | required | excluded

Required: No

The local storage types to include. You can specify hdd for hard disk drives, ssd for solid state drives, or both.

Type: Array of strings

Valid Values: hdd | ssd

Required: No

The maximum price for Spot instances as a percentage of the optimal On-Demand price. This provides more precise cost control for Spot instance selection.

Type: Integer

Required: No

The minimum and maximum amount of memory per vCPU in gibibytes (GiB). This helps ensure that instance types have the appropriate memory-to-CPU ratio for your workloads.

Type: MemoryGiBPerVCpuRequest object

Required: No

The minimum and maximum network bandwidth in gigabits per second (Gbps). This is crucial for network-intensive workloads that require high throughput.

Type: NetworkBandwidthGbpsRequest object

Required: No

The minimum and maximum number of network interfaces for the instance types. This is useful for workloads that require multiple network interfaces.

Type: NetworkInterfaceCountRequest object

Required: No

The price protection threshold for On-Demand Instances, as a percentage higher than an identified On-Demand price. The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon ECS selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold.

Type: Integer

Required: No

Indicates whether the instance types must support hibernation. When set to true, only instance types that support hibernation are selected.

Type: Boolean

Required: No

The maximum price for Spot instances as a percentage over the lowest priced On-Demand instance. This helps control Spot instance costs while maintaining access to capacity.

Type: Integer

Required: No

The minimum and maximum total local storage in gigabytes (GB) for instance types with local storage.

Type: TotalLocalStorageGBRequest object

Required: No
