An application team for a startup company is deploying a new multi-tier application into the AWS Cloud. The application will be hosted on a fleet of Amazon EC2 instances that run in an Auto Scaling group behind a publicly accessible Network Load Balancer (NLB). The application requires the clients to work with UDP traffic and TCP traffic. In the near term, the application will serve only users within the same geographic location. The application team plans to extend the application to a global audience and will move the deployment to multiple AWS Regions around the world to bring the application closer to the end users. The application team wants to use the new Regions to deploy new versions of the application and wants to be able to control the amount of traffic that each Region receives during these rollouts. In addition, the application team must minimize first-byte latency and jitter (randomized delay) for the end users. How should the application team design the network architecture for the application to meet these requirements?

AWS Global Accelerator: It is a service that uses static IP addresses as Anycast, which provides a fixed entry point for your applications. Global Accelerator directs traffic over the AWS global network to optimal AWS endpoint based on health, geography, and routing policies you configure. Listeners and Endpoint Groups: Global Accelerator allows you to configure listeners for the required ports and endpoint groups for each Region where your application is deployed. Traffic Dial: The traffic dial allows you to control the percentage of traffic that is directed to each endpoint group. This is particularly useful during rollouts or canary deployments, where you want to gradually shift traffic to a new version of the application. Minimizing Latency: AWS Global Accelerator is designed to provide low-latency, high-throughput, and fault-tolerant access to your applications.
Chose B2
B, because UDP has come into picture, so no better option than a Global Accelerator.
