【摘要】 随着虚拟化技术的成熟,云计算的优势逐渐显露出来,成本的低廉、资源利用率的提高、服务整合的节能以及服务使用的便捷。而获取这些优势的前提是需要一个有针对性的资源管理与应用服务平台,基于此,我们开发了CRANE云计算平台,融合了IaaS(Infrastructure as a Service)及PaaS(Platform as a Service)两个云计算服务层次,提出企业信息化云服务和科学计算云服务这两大类特色PaaS平台。CRANE平台采用虚拟化技术,在底层提供虚拟化资源,向IaaS和PaaS平台提供可定制的虚拟化环境支持。用户既可以利用PaaS平台享用通用的开发环境,又能通过IaaS平台申请所需资源,自主搭建满足自己需求的操作环境。更多还原

【Abstract】 With the maturity of virtualization technology, the advantages of cloud computing have been gradually apparent with low cost, improvement of resource utilization, energy conservation of service consolidation and convenience of using. The very first step of obtain these advantages is to build a targeted cloud platform for resources management and services provision. Therefore we have developed CRANE, a cloud computing platform integrated with the IaaS and PaaS service, and proposed two kinds of cloud services,enterprise informatization service and scientific computing service. With virtualization technology, CRANE can provide a customizable virtual environment for IaaS and PaaS platform. Users can not only make use of the common development environment of PaaS platform, but also apply the necessary resources from IaaS platform to flexibly build the environment to meet their own needs.更多还原
