Which AWS service supports this use case?

Explanations:

Amazon EC2 provides scalable virtual servers but requires more operational knowledge and management overhead, making it less suitable for a quick migration with limited expertise.

Amazon Lightsail is designed for simplicity, offering an easy-to-use interface and bundled resources for deploying websites and applications quickly, making it ideal for users with limited operational knowledge.

Amazon S3 is an object storage service, not a web hosting or database service, and does not provide the necessary infrastructure to run a website or database directly.

AWS Lambda is a serverless compute service ideal for running code in response to events but does not support hosting a website or a database directly, making it unsuitable for this migration scenario.
