Which AWS service will meet these requirements?

Explanations:

Amazon Connect is a cloud-based contact center service designed for customer service and call center needs. It does not support container management or serverless architectures.

AWS Fargate is a serverless compute engine for containers that allows users to run containers without managing the underlying infrastructure. It is ideal for migrating on-premises container infrastructure to the cloud while preventing unplanned costs.

Amazon Lightsail is a simplified cloud platform that provides virtual private servers and is not specifically designed for managing containerized applications or serverless architectures. It lacks the advanced container management features that AWS Fargate offers.

Amazon EC2 provides scalable virtual servers in the cloud but requires management of the underlying instances, which does not align with the requirement for a serverless architecture. It can lead to unplanned operational costs due to the need for instance management.
