云计算关键技术之弹性伸缩控制技术认知研究

Research on the cognition of elastic retractable control technology——one of the key technology of cloud computing

云计算的弹性伸缩控制技术因其以弹性可伸缩方式提供资源,提高了资源利用率和用户满意度,较好地解决了资源利用率和应用系统之间的矛盾,而成为云计算的关键技术。弹性伸缩控制技术,是指对一个系统适应负载变化进行调控的能力。弹性伸缩有纵横之分,弹性伸缩的需求是刚性、动态的。虚拟化技术的应用,使得弹性伸缩控制技术的优势发挥得更加充分。在弹性伸缩控制技术支持下,整合了动态负载均衡及资源配置机制的云计算中心,可以很好地解决大规模系统的有效管理问题,具有良好的应用前景。

Elastic retractable control technology is one of the key technology of cloud computing,as it can provide resources based on the elastic retractable way,improve the resource utilization and user satisfaction,and better solve the contradiction between resource utilization and application system.Elastic retractable control technology is the ability of controlling a system to adapt to the change of load.Elasticity has vertical and horizontal.The demand of elasticity is rigid,dynamic.The application of virtualization technology can make the advantage of elastic retractable control technology play more fully.Under the aegis of elastic retractable control technology,cloud computing centre which integrates the dynamic load balancing and resource allocation mechanism can better solve the effective management of large-scale system and has a good application prospect.
