Which solution will meet these requirements?
Setup a transit gateway in each Region. Create inter-Region peering attachments between each transit gateway.
Set up AWS Global Accelerator with UDP listeners and endpoint groups in each Region.
Set up Amazon CloudFront with UDP turned on. Configure an origin in each Region.
Set up a VPC peering mesh between each Region. Turn on UDP for each VPC.
Explanations:
Setting up a transit gateway with inter-Region peering attachments would facilitate communication between VPCs but does not inherently optimize for UDP traffic. Additionally, this approach may introduce additional latency due to routing complexity compared to other solutions.
AWS Global Accelerator is designed to improve the availability and performance of applications with global users. It provides static IP addresses that act as a fixed entry point to the application, uses the AWS global network to optimize the path to the application endpoints in each Region, and supports UDP, making it ideal for reducing latency and packet loss for online multiplayer games.
Amazon CloudFront is primarily a content delivery network (CDN) for HTTP/HTTPS traffic and is not optimized for real-time UDP traffic. Although CloudFront can enhance performance for static and dynamic web content, it does not meet the requirements for minimizing latency and packet loss in a UDP gaming scenario.
VPC peering allows communication between VPCs but does not optimize for UDP traffic specifically. Setting up a full mesh of peering connections would also increase complexity and potential latency due to multiple hops between VPCs, making it less suitable for a high-performance gaming environment compared to Global Accelerator.
I weigh that the answer is:
Set up AWS Global Accelerator with UDP listeners and endpoint groups in each Region.
