Weighted Least Connections
Weighted Least Connections is a load balancing algorithm used to distribute network traffic across multiple servers or resources. It selects the server with the fewest active connections relative to its assigned weight, allowing for proportional distribution based on server capacity. This method is commonly implemented in load balancers to optimize performance and resource utilization in distributed systems.
Developers should use Weighted Least Connections when managing heterogeneous server environments where servers have varying processing capabilities, such as in cloud deployments or mixed hardware setups. It is particularly useful for applications with long-lived connections, like database pools or real-time services, as it prevents overloading weaker servers while efficiently utilizing more powerful ones. This algorithm helps maintain system stability and responsiveness under varying loads.
