Load balancers distribute incoming requests across a pool of healthy backend servers to ensure scalability and reliability.
π Common Algorithms
1. Round Robin
Distributes requests sequentially in a circular order.
- Best for: Homogeneous servers with equal capacity and short-lived requests.
2. Least Connections
Directs requests to the server with the fewest active sessions.
- Best for: Long-lived connections (like databases, streaming, or WebSockets) where server load varies heavily.
3. IP Hash
Hashes the client's IP address to map them consistently to the same backend server.
- Best for: Stateful applications requiring session persistence ("sticky sessions").
