Which AWS service or resource will meet these requirements?

Explanations:

An Application Load Balancer (ALB) is designed to distribute incoming application traffic across multiple targets, such as EC2 instances, ensuring high availability and fault tolerance. It operates at the application layer (Layer 7) and can handle HTTP/HTTPS traffic efficiently.

AWS WAF (Web Application Firewall) is used to protect web applications from common web exploits and does not distribute traffic. It filters and monitors HTTP requests based on rules.

AWS CloudHSM is a hardware security module that helps with the management of cryptographic keys and does not relate to traffic distribution between EC2 instances.

AWS Direct Connect is a service that allows a dedicated network connection from your premises to AWS. It is used for establishing a secure connection but does not handle traffic distribution among EC2 instances.
