ABSTRACT:
A load balancing system is described herein that proactively balances client requests among multiple destination servers using information about anticipated loads or events on each destination server to inform the load balancing decision. The system detects one or more upcoming events that will affect the performance and/or capacity for handling requests of a destination server. Upon detecting the event, the system informs the load balancer to drain connections around the time of the event. Next, the event occurs on the destination server, and the system detects when the event is complete. In response, the system informs the load balancer to restore connections to the destination server. In this way, the system is able to redirect clients to other available destination servers before the tasks occur. Thus, the load balancing system provides more efficient routing of client requests and improves responsiveness.
