Amazon ECS Managed Instances now supports AWS Trainium and AWS Inferentia

Posted on: Jun 3, 2026

Amazon Elastic Container Service (Amazon ECS) Managed Instances now supports AWS Trainium and AWS Inferentia, purpose-built AI accelerators designed to deliver scalable performance and cost efficiency for training and inference across a broad range of generative AI workloads. Amazon ECS Managed Instances is a fully managed compute option designed to eliminate infrastructure management overhead while giving you access to the full capabilities of Amazon EC2. By offloading infrastructure operations to AWS, ECS Managed Instances helps you quickly launch and scale your workloads, while enhancing performance and reducing your total cost of ownership.

With ECS Managed Instances, you get the application performance you want and the simplicity you need. Now you can create an ECS Managed Instances capacity provider and select the desired accelerated instance types, including Inferentia2, Trainium1, and Trainium2, then add NEURON_CORE=all configuration to the ResourceRequirement section of your task definition. This will instruct Amazon ECS to launch the instances you’ve specified and place a single task per instance, automatically allocating all the resources of the accelerator to your workload for optimal performance.

To get started with ECS Managed Instances, use the AWS Console, Amazon ECS MCP Server, or your favorite infrastructure-as-code tooling to enable it in a new or existing Amazon ECS cluster. You will be charged for the management of compute provisioned, in addition to your regular Amazon EC2 costs.
