Elastic Load Balancing (ELB)

ELB automatically distributes incoming application traffic across multiple targets, such as EC2 instances.

Types of Load Balancers:

  1. Application Load Balancer (ALB): Layer 7 (HTTP/HTTPS). Routing based on URL path or hostname.
  2. Network Load Balancer (NLB): Layer 4 (TCP/UDP). Used for high-performance or static IPs.
  3. Gateway Load Balancer (GWLB): For 3rd party virtual appliances.
