What is Elastic Load Balancing?

An AWS service that automatically distributes incoming application traffic across multiple targets like EC2 instances and containers.

AWS offers three load balancer types: Application Load Balancer (HTTP/HTTPS, path-based routing, WebSocket), Network Load Balancer (TCP/UDP, ultra-low latency, millions of requests), and Gateway Load Balancer (third-party virtual appliances).

Features include health checks, auto-scaling integration, SSL termination, sticky sessions, cross-zone load balancing, and WAF integration. ALB supports host-based routing (multiple domains on one ALB) and weighted target groups for blue-green deployments.
