What Type of Load Balancing Algorithms Are Available?

Vultr Load Balancers support two traffic distribution algorithms to optimize request handling across backend servers:

• Round Robin: Traffic is distributed sequentially and evenly across all backend servers, without considering the current load on each server. It is suitable for stateless applications or servers with similar performance characteristics.
• Least Connections: Traffic is directed to the server with the fewest active connections, helping balance workloads for applications with long-lived or resource-intensive sessions. This prevents any single server from becoming a bottleneck while others remain underutilized.

Choosing the appropriate algorithm depends on application requirements and traffic patterns, enabling Load Balancers to maintain optimal performance and responsiveness.
