A company currently manages its own Docker environment on Amazon EC2 and wants a managed alternative that handles cluster sizing, scheduling, and environment maintenance. Which AWS service provides that functionality?

AWS Fargate is a serverless compute engine for containers that works with Amazon ECS and Amazon EKS. It eliminates the need to provision, configure, and scale clusters of virtual machines, allowing users to focus on building applications. Fargate handles the underlying infrastructure, including cluster sizing, scheduling, and environment maintenance, making it an ideal managed alternative for a company currently managing its own Docker environment on EC2. AWS Lambda is a serverless compute service for running code without provisioning or managing servers, but it's for functions, not container orchestration. Amazon RDS is a managed relational database service. Amazon Athena is an interactive query service for analyzing data in Amazon S3 using standard SQL.
