云计算与网格计算的比较研究

网格计算是一种能够整合零散资源并实现资源共享和协同工作的计算模式;云计算是网格计算、并行计算、分布式计算的发展,是一种新兴的商业计算模式。它具有与网格计算不同的新的特点。该文在研究网格计算与云计算概念的基础上从体系结构、专注方向、资源管理、作业调度等多种角度对网格计算与云计算进行了分析和研究。云计算所采用的商业理念、成熟的资源虚拟化技术以及非标准化的规范,使其体系结构、资源管理、作业调度等方面呈现出了不同的特点,也更适宜于为用户提供按需服务的目标,但在安全方面仍需不断完善。

Comparing Researh of Cloud Computing and Grid Computing

Grid computing a computing mode of merging scattered resources and realizing resources sharing and cooperative working;Cloud computing is the development of Grid computing,parallel computing and distributed computing,is a new business computing mode.It has some new characters,compared with grid computing.On the base of grid computing and cloud computing,Research the differences between grid computing and cloud computing,from kinds of degrees such as protocol architecture,direction of concentrating,resources...
