Question

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?

Accepted Answer

**Network Load Balancer (NLB)** is the correct choice because it satisfies every requirement:

1. **UDP Support**: NLB operates at **Layer 4 (Transport Layer)** and natively supports **TCP, UDP, and TLS** protocols. Game servers typically use UDP for real-time communication because it avoids the overhead of TCP's connection management and retransmission.

2. **Ultra-Low Latency**: NLB is designed for **extreme performance**. It uses a flow-based architecture that processes packets at the network level without deep packet inspection, resulting in latencies in the **microsecond range** — far lower than ALB's millisecond-range latency.

3. **Millions of Requests Per Second**: NLB can handle **millions of requests per second** and scales automatically to meet traffic spikes. It is architected
