Which AWS service eliminates the need to provision and manage the container hosts?

Explanations:

AWS Fargate is a serverless compute engine for containers that eliminates the need to provision and manage servers. Users can run containers without managing the underlying infrastructure.

Amazon FSx for Windows File Server is a fully managed native Microsoft Windows file system. It is not related to container management and does not eliminate the need for provisioning container hosts.

Amazon Elastic Container Service (Amazon ECS) is a container orchestration service that requires users to manage the underlying EC2 instances unless using Fargate as the launch type.

Amazon EC2 provides virtual servers in the cloud, requiring users to provision and manage the instances that run the containers, which contradicts the requirement of eliminating container host management.
