A Proactive Management Framework in Active Clusters

Abstract

Abstract. 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.

Event-Driven Management Automation in the ALBM Cluster System

“…As introduced in our previous research [6], the ALBM (Adaptive Load Balancing and Management) active cluster system is composed of active switches, application servers, and the management station.…”

“…The ALBM (Adaptive Load Balancing and Management) cluster system is an active cluster system that is scalable, reliable and manageable [6]. We developed this system for various research purposes, such as active traffic management, content-based delivery, middleware services for distributed systems, and proactive distributed system management.…”
