Which AWS service will meet these requirements?

Explanations:

Amazon EC2 (Elastic Compute Cloud) is primarily a compute service that provides scalable virtual servers for running applications. While it is essential for hosting applications, it does not provide DNS management or routing capabilities needed for globally accessible eCommerce.

Amazon VPC (Virtual Private Cloud) is a networking service that allows you to create a private network in the cloud. It helps in configuring security and connectivity but does not serve as a DNS web service for connecting users to applications.

Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service that provides DNS management, routing, and health checking. It allows the company to direct users to the nearest resources, ensuring a globally accessible eCommerce platform.

Amazon RDS (Relational Database Service) is a managed database service that provides scalable database solutions. While it is important for data management in an eCommerce platform, it does not handle DNS or routing tasks necessary for user connectivity.
