Amazon ECS (Elastic Container Service) is specifically designed to facilitate the deployment and management of containerized applications. It allows developers to run and scale Docker containers in a cluster of Amazon EC2 instances. ECS provides the tools and services to easily manage the lifecycle of containers while handling tasks such as scheduling and load balancing. With ECS, you benefit from integration with other AWS services, the ability to define task definitions that outline the containers and how they interact, and options for serverless deployments with Fargate.

The other options serve different purposes:

Amazon RDS (Relational Database Service) is focused on providing managed relational database services, not container handling.

Amazon EC2 (Elastic Compute Cloud) allows provisioning of virtual servers in the cloud and can run containers, but it does not provide the orchestration capabilities that ECS offers, making it less suitable for managing containerized applications directly.

AWS Lambda is a serverless compute service that lets you run code without provisioning servers, but it primarily focuses on event-driven applications rather than managing and orchestrating containers.

Thus, ECS is the most appropriate choice for running and managing containerized applications effectively within the AWS ecosystem.
