A Proactive Management Framework in Active Clusters

An active Web cluster system is an active network that has a collection of locally distributed servers that are interconnected by active switches, providing a Web application service. In this paper, we introduce the ALBM (Adaptive Load Balancing and Management) active cluster system that provides proactive management. The architecture of the ALBM active cluster and its underlying components are presented. We focus on system-level and service-level management of the active cluster system by presenting the corresponding proactive ALBM framework. The system-level framework considers performance counters of resource state dynamics; the service-level framework concerns service quality and proactive actions based on event occurrences. The experimental results on adaptive load balancing are presented in terms of system-level proactive management. In addition, a proactive event message service tool is introduced for providing effective services and management in terms of service-level proactive management.
