Load Balancing — System Design Roadmap
Distributing traffic across servers to improve scalability and availability
Steps in Load Balancing
- Load Balancing Algorithms — intermediate · Round robin, least connections, weighted and consistent-hashing based load balancing
- Layer 4 vs Layer 7 Load Balancing — intermediate · Load balancing at the transport layer vs the application layer
- Health Checks & Failover — intermediate · Detecting unhealthy servers and rerouting traffic automatically
- Global Server Load Balancing (GSLB) — intermediate · Routing users to the nearest healthy data center or region
