Your business hosts an application for the US market in the AWS region us-east-1. This program runs on Amazon Elastic Compute Cloud (EC2) instances using proprietary TCP and UDP protocols. On their own PCs, end users run a real-time, front-end application. This front-end application is aware of the service's DNS hostname.
You must ensure that the system is prepared for worldwide growth. End users must have the lowest possible latency while accessing the application.

How should you approach these criteria while using AWS services?

A. Register the IP addresses of the service hosts as ג€Aג€ records with latency-based routing policy in Amazon Route 53, and set a Route 53 health check for these hosts.
B. Set the Elastic Load Balancing (ELB) load balancer in front of the hosts of the service, and register the ELB name of the main service host as an ALIAS record with a latency-based routing policy in Route 53.
C. Set Amazon CloudFront in front of the host of the service, and register the CloudFront name of the main service as an ALIAS record in Route 53.
D. Set the Amazon API gateway in front of the service, and register the API gateway name of the main service as an ALIAS record in Route 53.
