Q782. 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?

Correct Answer: C. Configure a Network Load Balancer with the required protocol and ports for the internet traffic. Specify the EC2 instances as the targets.

Explanation

To meet the requirements of maintaining ultra-low latency for game servers that handle millions of UDP internet traffic requests each second in a cost-effective manner, the most suitable solution is:C. Configure a Network Load Balancer with the required protocol and ports for the internet traffic. Specify the EC2 instances as the targets.A Network Load Balancer (NLB) is designed to handle high volumes of traffic with ultra-low latency. It operates at the transport layer (Layer 4) of the OSI model and is well-suited for UDP traffic. By configuring an NLB with the required protocol and ports, and specifying the EC2 instances as the targets, the game servers can handle the millions of UDP internet traffic requests efficiently while maintaining low latency.Here's why the other options are not the most suitable choices:A. Configuring an Application Load Balancer (ALB): ALBs operate at the application layer (Layer 7) of the OSI model and are primarily designed for handling HTTP and HTTPS traffic. While ALBs can handle UDP traffic as well, they may introduce additional processing overhead and may not provide the same level of performance and ultra-low latency as an NLB for UDP traffic.B. Configuring a Gateway Load Balancer (GWLB): GWLB is designed for handling traffic between virtual networks and is not specifically optimized for handling internet traffic or UDP traffic. It may not provide the required level of performance and ultra-low latency for UDP internet traffic requests.D. Launching an identical set of game servers on EC2 instances in separate AWS Regions: While launching game servers in multiple AWS Regions can provide redundancy and fault tolerance, it does not directly address the requirement of handling millions of UDP internet traffic requests each second with ultra-low latency. It may introduce additional complexity and costs without directly improving the performance of handling UDP traffic.Therefore, the most cost-effective solution to maintain ultra-low latency for game servers that handle millions of UDP internet traffic requests each second is:C. Configure a Network Load Balancer with the required protocol and ports for the internet traffic. Specify the EC2 instances as the targets.
