Load Balancing Algorithms

Choose the right algorithm for your specific use case

Round Robin

Equal distribution across all backends

Distributes requests evenly across all available backend servers in a circular order. Each backend receives an equal share of traffic regardless of current load or capacity.

Best For:

Homogeneous server environments with identical capacity
Stateless applications without session requirements
Simple deployments with predictable traffic patterns
