面向SLA的云计算资源调配:挑战、架构和解决方案

SLA-Oriented Resource Provisioning for Cloud Computing: Challenges, Architecture, and Solutions

Rajkumar Buyya, Saurabh Kumar Garg, Rodrigo N. Calheiros

摘要:

云计算系统承诺为全球用户提供面向订阅的企业级计算服务。随着向大量用户提供服务的需求增加,他们需要为用户提供差异化服务,并满足他们的质量期望。数据中心中现有的资源管理系统尚未支持面向服务水平协议(SLA)的资源分配,并且因此需要增强以实现云计算和效用计算。此外,还没有完成将客户驱动的服务管理、计算风险管理和自主资源管理共同合并到基于市场的资源管理系统中以瞄准云计算的快速变化的企业需求的工作。本文介绍了面向SLA的资源管理的愿景、挑战和架构元素。建议的架构支持基于市场的配置策略和虚拟化技术的集成,以灵活地将资源分配给应用程序。从我们的工作原型系统的性能结果表明,在云中基于SLA的资源提供的可行性和有效性。

英文摘要:

Cloud computing systems promise to offer subscription-oriented, enterprise-quality computing services to users worldwide. With the increased demand for delivering services to a large number of users, they need to offer differentiated services to users and meet their quality expectations. Existing resource management systems in data centers are yet to support Service Level Agreement (SLA)-oriented resource allocation, and thus need to be enhanced to realize cloud computing and utility computing. In addition, no work has been done to collectively incorporate customer-driven service management, computational risk management, and autonomic resource management into a market-based resource management system to target the rapidly changing enterprise requirements of Cloud computing. This paper presents vision, challenges, and architectural elements of SLA-oriented resource management. The proposed architecture supports integration of marketbased provisioning policies and virtualisation technologies for flexible allocation of resources to applications. The performance results obtained from our working prototype system shows the feasibility and effectiveness of SLA-based resource provisioning in Clouds.
