An online video game company must maintain ultra-low latency for its game servers. The game servers run on Amazon EC2 instances. The company needs a solution that can handle millions of UDP internet traffic requests each second. Which solution will meet these requirements MOST cost-effectively?

A Network Load Balancer (NLB) is the most cost-effective solution for this scenario because it is designed for extreme performance and static IP addresses, making it ideal for handling millions of UDP requests per second with ultra-low latency. NLBs operate at Layer 4 (transport layer) and can handle volatile traffic patterns. Application Load Balancers (ALBs) operate at Layer 7 (application layer), adding more latency and are not optimized for UDP traffic. Gateway Load Balancers (GLBs) are designed for deploying and managing virtual appliances, not direct game server traffic. Launching identical game servers in separate regions would increase latency for users connecting to the non-local region and significantly increase costs without directly addressing the load balancing requirement for a single region.
