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.

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

  • cpuArchitecture: The CPU architecture (X86_64 or ARM64).

  • instanceGeneration: The instance generation (current, previous, or all).

  • burstablePerformance: Whether to include burstable performance instances (included, excluded, or required).

  • cpuManufacturer: The CPU manufacturer (intel, amd, or amazon-web-services).

  • networkBandwidth: The minimum network bandwidth in Gbps.

  • networkInterfaceCount: The minimum number of network interfaces.

  • localStorage: Whether local storage is required (included, excluded, or required).

  • localStorageType: The type of local storage (hdd or ssd).

Cost optimization

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

  • Reserved Instances (RIs): Amazon ECS Managed Instances tasks can benefit from RIs that you've purchased for the instance types used by your tasks.

  • Multi-task placement: Amazon ECS Managed Instances places multiple tasks on a single general-purpose instance by default, optimizing resource utilization and cost.
