Explanation
Network Load Balancer (NLB) operates at Layer 4 (TCP/UDP) and is purpose-built for extreme performance - handling millions of requests per second with ultra-low latency (single-digit milliseconds), making it the only option designed for that scale. The Classic Load Balancer is a legacy option that works across both Layer 4 and 7 but lacks the performance optimizations of modern alternatives. The Application Load Balancer operates at Layer 7 (HTTP/HTTPS) and excels at content-based routing and microservices, but trades raw throughput for intelligence. DNS Round Robin is not a true load balancer at all - it simply rotates DNS records, with no health checking, session persistence, or latency awareness.
Memory tip: Think "N for Network = N for Nanosecond-fast" - NLB handles network-level traffic at the highest speed, while ALB handles application-level smarts.
