What kind of virtualization technology to choose for the cloud computing platform will be a problem that cloud computing construction will face. This article compares and analyzes the architecture levels of the four mainstream virtualization technologies.

Tenkine Server channel Since the beginning of 21st century, when VMware released its server product line, the server virtualization of the X86 architecture has evolved into a vibrant market, and in the early years, it was almost the VMware family. But in 2006, Xen released its first commercial version, and then Microsoft released Hyper-V in 2008, and there were more and more alternatives in the market. The initial server virtualization was used to reduce costs, and later, with the advent of cloud computing, the server virtualization market warmed up again. X86 architecture ...

Virtual Machine Management program is a commodity, then where do we go? 　　Virtualized physical computers are the backbone of the public cloud [note] and private cloud [note], enabling enterprises to optimize hardware utilization, enhance security, support multi-tenant, and so on. Early virtualization approaches were based primarily on analog CPUs, such as x86 on PowerPC Macs, enabling users to run DOS and Windows. 　　Not only do you need to simulate CPUs, but you also simulate other components in your hardware environment, including graphics adapters, hard disks, network adapters, memory, and interfaces. ...

Microsoft released a beta version of Microsoft's System Center product, Virtual Machine Manager (VM Manager, VMM), hoping to regain user confidence in the competition with VMware. System Center is one of the Microsoft server-facing management software suite products, its first version of Microsoft System Center O ...

Open source technology has begun to deeply affect the world of cloud computing. There are two main reasons: first, open source software is essentially free, and it is generally not affected by proprietary software copyright models. 　　Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain outdated and expensive license patterns, even though this pattern has hampered the flexibility of virtualization and cloud computing. Conversely, some open source tools are having a huge impact on the public cloud: Linux and Xen, for example. In addition, there are some other important open source tools also for users ...

If you want to create a private cloud, you need to use management software to create a virtual pool of computing resources, provide access to end users, and deal with security, resource allocation, tracking and billing issues. We tested five mainstream private cloud management products: Novell's Cloud Manager,eucalyptus Enterprise Edition, Opennebula,citrix Lab Manager and cloud.com cloudstack ...

The intermediary transaction SEO diagnoses Taobao guest Cloud host technology Hall VPS is virtual private server abbreviation, literal translation is the fictitious dedicated servers. 　　As the name suggests, it is not a real physical server, but it is also different from the shared Hosting (virtual host), users have full control of the VPS, that is, root Access. The characteristics of the VPS 1, relatively independent user isolation: Users no longer because of a variety of resources and fighting, between each other in a relative separation ...

High-tech competition in the Internet era, the delivery of products gradually shortened, and the quality of delivery requirements gradually increased, a variety of new ideas, new products, market-allowed product launch cycle is also getting shorter, the traditional software development model has been unable to keep up with the current needs, efficient, convenient, The iterative product development pattern is becoming more and more popular, and virtualization technology is the most important tool to embody this development pattern. Functionally speaking, the advantage of virtualization is to improve the utilization of resources, the second is to provide a variety of configuration management; The third is to provide a snapshot of the preservation and recovery functions;

Virtualization is the first step toward the cloud, and, similarly, open source virtualization is the first step toward an open source cloud. Cloud computing offers products and solutions that revolve around the new delivery and consumption patterns of IT resources. The diversity of the cloud, the private cloud, the public cloud and the hybrid cloud, no matter which cloud has three key characteristics: virtualization, standardization and automation. So, what's a KVM? Can it meet the needs of the enterprise to the cloud? What's a KVM? KVM (kernel-based Virtual Machine) Source ...

From the Institute of Software Research, Chinese Academy of Sciences, National Engineering Research Center system security and Trusted computing, Ms. Ding Liping for you to share "cloud computing environment covert channel analysis." 　　She described in detail the three aspects of covert channels, security threats and covert channels in cloud computing environments, and their work. ▲ Software Institute of Chinese Academy of Sciences the concept of covert channel covert channel at operating system level refers to the way that malicious process realizes information leakage through collusion information system (Ding Liping), and the covert channel analysis is the security standard at home and abroad.
