An e-commerce company wants to distribute incoming traffic across the EC2 instances hosting its website. Which AWS service should it use?

The Application Load Balancer (ALB) is the correct choice because it operates at the application layer (Layer 7 of the OSI model) and is designed to distribute incoming application traffic across multiple targets, such as EC2 instances. This ensures high availability and fault tolerance for the e-commerce website. ALBs can also route traffic based on content, host, or path, which is beneficial for complex applications. AWS WAF (Web Application Firewall) is incorrect because it is a security service that helps protect web applications from common web exploits, not a load balancing service. AWS CloudHSM is incorrect because it provides hardware security modules (HSMs) in the AWS Cloud for cryptographic operations, not traffic distribution. AWS Direct Connect is incorrect because it establishes a dedicated network connection from your on-premises data center to AWS, not for distributing traffic among EC2 instances.
