InstanceRequirementsRequest
The instance requirements for attribute-based instance type selection. Instead of specifying exact instance types, you define requirements such as vCPU count, memory size, network performance, and accelerator specifications. Amazon ECS automatically selects Amazon EC2 instance types that match these requirements, providing flexibility and helping to mitigate capacity constraints.
Types
Properties
The minimum and maximum number of accelerators for the instance types. This is used when you need instances with specific numbers of GPUs or other accelerators.
The accelerator manufacturers to include. You can specify nvidia, amd, amazon-web-services, or xilinx depending on your accelerator requirements.
The specific accelerator names to include. For example, you can specify a100, v100, k80, or other specific accelerator models.
The minimum and maximum total accelerator memory in mebibytes (MiB). This is important for GPU workloads that require specific amounts of video memory.
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.
The instance types to include in the selection. When specified, Amazon ECS only considers these instance types, subject to the other requirements specified.
The minimum and maximum baseline Amazon EBS bandwidth in megabits per second (Mbps). This is important for workloads with high storage I/O requirements.
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.
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.
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.
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.
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.
The local storage types to include. You can specify hdd for hard disk drives, ssd for solid state drives, or both.
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.
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.
The minimum and maximum amount of memory in mebibytes (MiB) for the instance types. Amazon ECS selects instance types that have memory within this range.
The minimum and maximum network bandwidth in gigabits per second (Gbps). This is crucial for network-intensive workloads that require high throughput.
The minimum and maximum number of network interfaces for the instance types. This is useful for workloads that require multiple network interfaces.
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.
Indicates whether the instance types must support hibernation. When set to true, only instance types that support hibernation are selected.
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.
The minimum and maximum total local storage in gigabytes (GB) for instance types with local storage.
The minimum and maximum number of vCPUs for the instance types. Amazon ECS selects instance types that have vCPU counts within this range.
