Which AWS service will meet this requirement?

Explanations:

AWS Lambda is a serverless compute service that automatically manages the infrastructure and allows you to run code in response to events.

AWS CloudFormation is a service for provisioning and managing AWS resources using templates, not a compute service.

AWS Elastic Beanstalk is a platform as a service (PaaS) that simplifies the deployment of applications but is not serverless as it involves managing the underlying resources.

Elastic Load Balancing is used to distribute incoming application traffic across multiple targets, but it does not provide serverless compute capabilities.
