技术领域technical field
本发明涉及云计算技术领域，特指一种基于云计算的虚拟机运行控制装置及其运行控制方法。The invention relates to the technical field of cloud computing, in particular to a cloud computing-based virtual machine operation control device and an operation control method thereof.
背景技术Background technique
计算机的应用模式大体经历了以大型机为主体的集中式架构(数据中心1.0)、以PC机为主体的客户/服务器分布式计算架构(数据中心2.0)、以虚拟化技术为核心面向服务的体系结构(SOA)及基于Web2.0应用特征的新型架构(数据中心3.0)。计算机的应用模式、技术架构及实现特征的演变是云计算发展的时代背景。The computer application model generally experienced a centralized architecture with mainframes as the main body (data center 1.0), a client/server distributed computing architecture with PCs as the main body (data center 2.0), and a service-oriented architecture with virtualization technology as the core. System Architecture (SOA) and a new architecture based on Web2.0 application characteristics (Data Center 3.0). The evolution of computer application modes, technical architecture and implementation features is the background of the development of cloud computing.
云计算的实质是网络下的应用，是由lP和lT技术共同构建的。从发展的角度来看，“云”的技术和目标是一个逐步演化的过程。比如，Web技术出现时，就具备了云计算的应用特征有了统一界面的雏形。随着服务器应用平台上的虚拟化技术的成熟和Web统一界面的推出，虚拟化和Web走向结合，使得云计算可以在一个整合的架构上统一实现。The essence of cloud computing is the application under the network, which is jointly constructed by lP and lT technologies. From the perspective of development, the technology and goal of "cloud" is a process of gradual evolution. For example, when Web technology appeared, it possessed the application characteristics of cloud computing and had the embryonic form of a unified interface. With the maturity of the virtualization technology on the server application platform and the launch of the unified web interface, the combination of virtualization and the web enables cloud computing to be implemented uniformly on an integrated architecture.
虚拟化是一个广义的术语，在计算机方面通常是指计算元件在虚拟的基础上而不是真实的基础上运行。虚拟化技术可以扩大硬件的容量，简化软件的重新配置过程。CPU的虚拟化技术可以单CPU模拟多CPU并行，允许一个平台同时运行多个操作系统，并且应用程序都可以在相互独立的空间内运行而互不影响，从而显著提高计算机的工作效率。Virtualization is a broad term generally used in computing to refer to computing elements operating on a virtual basis rather than a real one. Virtualization technology can expand the capacity of hardware and simplify the process of reconfiguring software. CPU virtualization technology can simulate multiple CPUs in parallel with a single CPU, allowing one platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thereby significantly improving computer work efficiency.
虚拟化技术与多任务以及超线程技术是完全不同的。多任务是指在一个操作系统中多个程序同时并行运行，而在虚拟化技术中，则可以同时运行多个操作系统，而且每一个操作系统中都有多个程序运行，每一个操作系统都运行在一个虚拟的CPU或者是虚拟主机上；而超线程技术只是单CPU模拟双CPU来平衡程序运行性能，这两个模拟出来的CPU是不能分离的，只能协同工作。Virtualization technology is completely different from multitasking and hyperthreading technology. Multitasking means that multiple programs run in parallel in one operating system at the same time. In virtualization technology, multiple operating systems can run at the same time, and each operating system has multiple programs running. It runs on a virtual CPU or a virtual host; and hyper-threading technology is just a single CPU simulating dual CPUs to balance the performance of the program. The two simulated CPUs cannot be separated and can only work together.
虚拟化技术也与目前VMware Workstation等同样能达到虚拟效果的软件不同，是一个巨大的技术进步，具体表现在减少软件虚拟机相关开销和支持更广泛的操作系统方面。Virtualization technology is also different from the current VMware Workstation and other software that can also achieve virtual effects. It is a huge technological advancement, which is specifically reflected in the reduction of software virtual machine-related overhead and support for a wider range of operating systems.
