What Type of Load Balancing Algorithms Are Available?

Updated on 15 September, 2025

Overview of traffic distribution algorithms supported by Vultr Load Balancers for optimizing request handling across backend servers


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.
