Instance selection methods

Amazon ECS Managed Instances provides two methods for selecting instance types:

• Specific instance type selection: You explicitly specify the EC2 instance type to use for your tasks.

• Attribute-based instance type selection: You specify the attributes (such as vCPU, memory, and architecture) that your application requires, and Amazon ECS Managed Instances selects an appropriate instance type.

Specific instance type selection

With specific instance type selection, you explicitly specify the EC2 instance type to use for your Amazon ECS Managed Instances tasks. This is useful when your application requires a specific instance type with particular hardware characteristics.

Attribute-based instance type selection

With attribute-based instance type selection, you specify the attributes that your application requires, and Amazon ECS Managed Instances selects an appropriate instance type that meets those requirements. This provides more flexibility and can help ensure that your tasks are placed successfully even if specific instance types are not available.

When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values.

The following attributes are supported for attribute-based instance type selection:

cpuArchitecture

The CPU architecture.

Valid values: X86_64 | ARM64

instanceGeneration

Indicates whether current or previous generation instance types are included.

• For current generation instance types, specify current. The current generation includes EC2 instance types currently recommended for use. This typically includes the latest two to three generations in each instance family. For more information, see Instance types in the Amazon EC2 User Guide.

• For previous generation instance types, specify previous.

• To include both current and previous generation instance types, specify all.

Valid values: current | previous | all

Default: Any current or previous generation.

burstablePerformance

Indicates whether burstable performance instance types are included, excluded, or required. For more information, see Burstable performance instances in the Amazon EC2 User Guide.

Valid values: included | excluded | required

Default: excluded

cpuManufacturer

Lists which specific CPU manufacturers to include.

• For instance types with Intel CPUs, specify intel.

• For instance types with AMD CPUs, specify amd.

• For instance types with AWS CPUs (such as AWS Graviton), specify amazon-web-services.

Note

Don't confuse the CPU hardware manufacturer with the CPU hardware architecture. Instances will be launched with a compatible CPU architecture based on the Amazon Machine Image (AMI) that you specify.

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

Default: Any manufacturer.

networkBandwidth

The minimum and maximum amount of network bandwidth, in gigabits per second (Gbps).

Default: No minimum or maximum limits.

networkInterfaceCount

The minimum and maximum number of network interfaces.

Default: No minimum or maximum limits.

localStorage

Indicates whether instance types with instance store volumes are included, excluded, or required. For more information, see Amazon EC2 instance store in the Amazon EC2 User Guide.

Valid values: included | excluded | required

Default: included

localStorageType

Indicates the type of local storage that is required.

• For instance types with hard disk drive (HDD) storage, specify hdd.

• For instance types with solid state drive (SSD) storage, specify ssd.

Valid values: hdd | ssd

Default: Any local storage type.

Billing and purchase options

Amazon ECS Managed Instances supports several features to help optimize the cost of your containerized workloads:

• Savings Plans (SPs): Amazon ECS Managed Instances benefit from Savings Plans that you've purchased for the instance types used by your tasks. No additional configuration is required.

• Reserved Instances (RIs): Amazon ECS Managed Instances tasks can benefit from RIs that you've purchased for the instance types used by your tasks. No additional configuration is required.

• Spot Instances: You can configure Amazon ECS Managed Instances capacity provider to use EC2 Spot instances by setting capacityOptionType=Spot

• Capacity Reservations: You can configure Amazon ECS Managed Instances capacity provider to use your EC2 Capacity Reservations by setting capacityOptionType=Reserved and providing a capacity reservation group. You can also specify following reservation preferences: use reservations-only to ensure instances launch exclusively in reserved capacity for maximum predictability, reservations-first to prefer reservations while maintaining flexibility to fall back to on-demand capacity when needed, or reservations-excluded to prevent your capacity provider from using reservations altogether.
