Cloud Computing Virtualization

Analysis and estimation of the construction scale of cloud computing virtualization system based on system Dynamics LI Yujian Kozun The System Dynamics analysis method is used to establish the scheduling model of virtual machine in cloud computing virtual environment. By means of computer system simulation, using system Dynamics model and method, this paper studies the business demand and construction scale of cloud computing virtual machine from the system point of view, and finds out the key factors affecting the number of virtual machines. Further, the decisive factor of calculating resource pool scale construction, using mathematical Statistics theory and method, put forward the optimization estimate construction scale ...

Application and development trend of cloud computing virtualization in power Enterprises Summary: Cloud Computing is an internet-based computing method in which shared hardware and software resources and information can be provided to computers and other devices as needed. A cloud is a pool of resources that contains a large number of available virtual resources, such as hardware, development platforms, and I/O services, that can be reconfigured dynamically based on different workloads to achieve more optimized resource utilization. Keywords: cloud computing Virtualization application Development Trend temp_120 ...

Research and implementation of security mechanism among cloud computing client virtual machines The flexible services provided by the Choran Hu Junrong cloud computing rely on the support of virtualization technology, but the security problems of virtualization technology also pose a serious threat to the security of cloud computing. In view of the security risks faced by the client operating system in the cloud computing virtualization technology, based on the analysis of the requirements and characteristics of cloud computing virtualization technology, this paper designs the centralized management of cloud computing environment, the forced access control of distributed implementation and the isolation mechanism based on cloud resource control to make it cooperate with each other. Ensure the security of the client operating system in cloud computing and make the ...

Dong Guishan, Deng Chunmei, Deng Virtualization Network technology is the key to building a new generation of cloud computing data centers to provide infrastructure support for cloud computing environments. On the basis of studying the typical architecture and Access application mode of cloud computing data Center, this paper analyzes the security requirement of data center virtualization network from the aspects of user security access, communication isolation and confidentiality protection, and puts forward the security technology framework of virtualization network, focusing on the enhancement of virtualization network security based on cryptography technology, Protect the communication between virtual machines, information isolation and security exchange and other security mechanisms ...

In the August 29 news of the Beijing time, VMware unveiled the Vcloud suite at the VMworld conference this week and painstakingly explained the significant difference in functionality and naming between the Vcloud security model and the existing Vsphere Cloud computing virtualization operating system. VMware's underlying security technology has been known as VShield, which is essentially a technical approach in the vsphere, involving a set of APIs in the Edge and app Datacenter products that support agentless use of third-party security products. Vshiel ...

The key technology of cloud computing has three main points: ⑴ Virtualization Technology: The virtualization Technology of cloud computing is different from the traditional single virtualization, it is the entire IT architecture, including resources, network, application and desktop system-wide virtualization, its advantage is to be able to isolate all hardware devices, software applications and data, break the hardware configuration 　　, software deployment and data distribution, to realize the dynamic of it architecture, to achieve centralized resource management, so that applications can dynamically use virtual and physical resources to improve the system's ability to adapt to demand and environment. For information system simulation, cloud ...
