How it works

Algorithms

Round robin, least connections, and hashing strategies route requests based on different goals.

Layers

Layer 4 balancers route by transport connection; layer 7 balancers route by application data like URLs.

Health and failover

Balancers run health checks and remove unhealthy instances to keep the service available.

Interview concept
