An application deployed on EC2 instances across multiple Availability Zones must scale to millions of requests per second and handle highly variable, bursty traffic. The solution must provide a single static IP address per Availability Zone. Which service satisfies these requirements for distributing traffic to the instances?

A Network Load Balancer (NLB) is the correct choice because it is designed for extreme performance, handling millions of requests per second with ultra-low latency, making it ideal for highly variable and bursty traffic. It also provides a static IP address per Availability Zone, a key requirement. An Application Load Balancer (ALB) operates at Layer 7 and is suitable for HTTP/HTTPS traffic, but an NLB (Layer 4) offers superior performance and static IPs. AWS Global Accelerator provides static Anycast IP addresses at the edge, improving global performance, but it's not a direct load balancer for EC2 instances within a region. Amazon SQS is a message queuing service, not a load balancer.
