Using performance model to analyze the Internet service is prevailing. However, the research of the performance model for mail server retrains in the immature status. In this paper, based on the queue theory, we propose a performance model for Domino mail server. The verification and analysis of the model are also presented. The experimental results show that this model characterizes the behavior...
With the resurgence of virtualization technology, todaypsilas Internet data centers are shifting towards virtualized data centers. Internet applications tend to see dynamically varying workloads. To address the problem of performance management for multi-tier applications hosted in virtualized Internet data center, we propose a three-level automatic provisioning framework based on feedback control...
The complexity of the high performance Web-based application challenges the traditional approaches, which fail to guarantee the reliability and real-time performance required. In this paper, we have studied the adaptive mechanisms for managing such applications and explained them based on a prototype of an adaptive application management system (AMUS) in cluster. AMUS is composed of the SLA event-driven...
The complexity of the high performance Web-based application challenges the traditional approaches, which fail to guarantee the reliability and real-time performance required. In this paper, we present a prototype of a cluster-based adaptive application management system (AAMS), which is composed of the SLA event-driven global resource manager, the server resource manager and the self-adapting application...
How to provide better services for cluster users along with the cluster technology gains ground? An integrated cluster OS with friendly user environment is a trend. On the basis of Fire-Phoenix, a fully integrated, highly reliable and scalable cluster OS, the PWP (fire-Phoenix Web Portal) aims to provide one-station services for all kinds of cluster users. The PWP is a friendly, secure and flexible...
