面向Internet数据中心的资源管理

摘要

Internet data centers are developing towards a diversified, intelligent, automated, large-scaled, and standardized direction. With the increasing of scale and complexity, it brings great challenges in how to effectively manage resources. Currently, resource management has become a major issue in Internet data centers, and its importance and urgency cannot be ignored. This paper analyzes two major challenges of resource management with which the Internet data center is facing: (1) meeting the compatibility of concurrent and multiple application SLAs (service level agreements); (2) improving the energy efficiency of system service. Based on the challenges, this paper thoroughly analyzes and summarizes the related work of resource management guaranteeing the SLA, reducing power, and incorporating the objectives of guaranteeing the SLA and reducing power simultaneously during the last ten years. Finally, the paper summaraizes the research and points out future research directions.%Internet数据中心向多元化、智能化、自动化、规模化与标准化道路发展,其规模越来越大、越来越复杂,这为如何有效管理资源带来极大的冲击与挑战.当前,资源管理已成为Internet数据中心亟待解决的重要问题,其重要性与紧迫性已不容忽视.分析了Internet数据中心资源管理面临的两大挑战:(1)满足并发多应用SLAs(servicelevel agreements)的兼容性；(2)提高系统服务的能量有效性.以挑战为主线,对近十几年来国内外在满足SLA、降低功耗、同时满足SLA和降低功耗方面所取得的资源管理研究成果进行了全面的概括总结和分析,最后进行总结并对未来的研究发展趋势提出观点.
