Elastic Load Balancing
In plain terms
AWS's service for distributing traffic across resources.
Going deeper
ELB automatically spreads incoming traffic across multiple targets (instances, containers) for availability and scale, with health checks. It's AWS's managed load balancer.
Under the hood
Types include Application (L7), Network (L4), and Gateway load balancers for different needs.
Examples
Distributing web traffic, ALB/NLB, high availability, auto-scaling, AWS apps.
Think of it like...
Like an automatic host directing arrivals across all open service counters.
