摘要
虚拟化是云计算的本质核心问题,由于所涉及的技术问题宽泛,从纵向及横向综合进行分析。结合云桌面应用系统实例、网络中间层驱动开发实例、Windows操作系统驱动例子程序File Disk.c及Http Disk.c,通过分析操作系统内核,研究云计算原理、体系结构,以及云计算实现的技术基础,从硬件的虚拟化、系统的虚拟化两个方面展开研究,并在此基础上结合驱动技术调用操作系统内核接口实现部分操作系统内核功能。采用网络中间驱动技术实现了虚拟网卡,同时结合其他云计算系统的应用及对其维护经验,分析了云计算虚拟技术底层有关问题及解决办法,得出云计算虚拟化技术设计及实现的分层结构、调用操作系统内核接口可解决系统蓝屏并提高实时响应效率的结论。实例应用表明,云计算的体系结构的构建及实现是基于软件、硬件及系统虚拟化的。
Virtualization is the essential core of the cloud computing. Because the technical issues involved are broad, analysis with the vertical and horizontal integration point of view have been conducted. Some cases and examples have been investigated, such as cloud desktop application system which is used in colleges and universities, N-DIS programming cases, and windows operating system driver pro- gramming cases both FileDisk. c and HttpDisk. c. The research processing has been carded on two factors, one of which is virtualization of hardware, the other is virtualization of system, and in the research processing, several factors are to be considered, such as the kernel op- erating system, the theory of cloud computing and structure, and the implementation techniques of cloud computing. Based on analyzing these programming cases and examples, the bottom technologies concerned with cloud computing and virtualization problems have been resolved. Experimental results show that to design and implement cloud computing and virtualization are based on layered structure sys- tem, also based on invoking operation system kernel interface, not only Blue Screen of Death can be solved but also computing and virtu- alization system efficiency can be promoted in this way. Results of practical application show that the architecture and implementation of cloud computing architecture is based on software, hardware and system virtualization.
