Cloud Virtual Machine Comparison

"Editor's note" in the cloud computing ecosystem, there are two types of users that need to use cloud computing resources: the traditional (traditional IT applications) and the emerging Cloud computing Application (Cloud-aware applications) in the Internet tide. A popular metaphor abroad is that in the traditional service mode, it can be imagined that the server is the IT pet (Pets), give them name, carefully raised, when they are sick, you have to repair them; in the new form of application service model, virtual machine ...

A virtual machine deployment algorithm for reducing energy consumption in cloud environment Zhou Zhou Hu Zhigang to reduce the energy consumption of large-scale data centers, a virtual machine (VR Machine, VM) deployment algorithm is proposed TESA (Three-threshold power Saving algorithm) This algorithm uses energy consumption and processing resource utilization to linear relationship, will overload and load over light host ...

"Csdn Live Report" December 2014 12-14th, sponsored by the China Computer Society (CCF), CCF large data expert committee contractor, the Chinese Academy of Sciences and CSDN jointly co-organized to promote large data research, application and industrial development as the main theme of the 2014 China Data Technology Conference (big Data Marvell Conference 2014,BDTC 2014) and the second session of the CCF Grand Symposium was opened at Crowne Plaza Hotel, New Yunnan, Beijing. 2014 China large data Technology ...

Research on virtual machine dynamic migration strategy based on Xen Zhang Pu Liaoning University in this paper, a dynamic migration strategy based on Xen virtual machine is proposed for the Xen platform environment, combining the actual application scenario and the Xen bottom migration. The specific work is as follows: first, in order to carry out virtual machine migration in the cloud computing environment, Xen Migration uses a comparison between passing the page bitmap and skipping the page bitmap to determine whether the memory page is retransmission. For page bitmap comparison brings multiple retransmission increase network transmission overhead, put forward the memory optimization algorithm based on AR model, according to the memory page of the record all modified ...

Overview of Virtual machine system security Shen Zhi, Zhang Qun, Dichen with the wide application of cloud computing, virtual machine technology has been revived and developed, but it also brings new security threats, so the research on the security threat and defense of virtual machines has become a hotspot in the field of computer security. Taking the current widely used virtual machine Xen as an example, this paper analyzes the existing vulnerabilities and threats according to the technical characteristics of virtual machines, and puts forward the corresponding defense and protection methods from the angle of computer security science. A more comprehensive summary of the current domestic and foreign research on the safety of virtual machines related to the ...

Virtual machine migration time memory optimization algorithm based on Xen Chen Tingwei Zhang Pu Zhang Zhongqing for virtual machine migration in a cloud computing environment, Xen Migration uses a comparison between passing a page bitmap and skipping a page bitmap to determine whether the memory page is retransmission. The problem of multiple retransmission to increase network transport overhead for page bitmap comparisons A memory optimization algorithm based on AR model is proposed, which predicts the next time of memory page modification according to the memory page modification time interval of all records, and retransmission when the next modification time is greater than a certain threshold. The experimental results show that the base ...

May 23-May 25, 2012 cloud base of China Cloud Computing Conference opened the curtain, show cloud practice, explore cloud trend, share cloud future. The cloud base shows the latest technologies and new products in the field of cloud computing, and discusses the development trend of cloud computing, the great value of large data, the energy-saving of data center in cloud times and so on. 　　Tian Yun Technology product manager Guo Hong for guests to introduce Skyform cloud platform. Good afternoon, the sky Cloud Technology in May officially released the Cloud Platform 1.1 version, now the product name is SK ...

September 23, virtualization technology for the Linux kernel Xen was given a hat-trick with 3 security vulnerabilities. Xen vulnerabilities can be jumped out of the virtual host environment (ultra vires), or read other user data, control the hypervisor itself (host). A remote attacker could exploit a vulnerability that could cause the host system to crash and deny service to legitimate users. Xen Vulnerabilities and impact range is not small, such as Amazon AWS Large-scale restart server-the entire repair cycle lasted 5 days (from September 25 7 o'clock in the afternoon to September 30 5 o'clock in the afternoon), impact ...

As an important form of cloud computing, IaaS services have a wide range of open source and commercial cloud platform scenarios. This article is based on the use of open source IaaS cloud platform to develop public and private cloud management platform perspective, introduced and compared eucalyptus, Opennebula, Cloudstack and OpenStack, such as open source IaaS cloud platform. The characteristics of the successful cloud platform from AWS AWS is the most successful cloud computing platform, the most important feature of the system architecture is to open the data and function through the Web service interface.

Virtualization has injected unprecedented energy into Hadoop, from the point of view of IT production management as follows: • Hadoop and other applications consuming different types of resources together deploy shared data centers to increase overall resource utilization; • Flexible virtual machines Operations allow users to dynamically create and extend their own Hadoop clusters based on data center resources, as well as shrink the current cluster and free resources to support other applications if needed.
