Cloud computing is able to provide a virtualized pool of resources, flexible service capabilities, self-service, etc., won the CIO's favor, in order to improve the utilization of IT equipment, improve the capacity of service disaster, improve the rapid response to business support, the majority of enterprises are beginning to try the private cloud construction. The embarrassing situation of private cloud security in general, the transition from the existing IT management system to the private cloud platform requires several steps: Large data centralization, business system integration, virtualization of IT resources, management platform cloud, and cloud service delivery. (many people think that private clouds ...

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 embarrassing situation of private cloud security in general, the transition from the existing IT management system to the private cloud platform requires several steps: Large data centralization, business system integration, virtualization of IT resources, management platform cloud, and cloud service delivery. (Many people think that the private cloud is the construction of the information center, in fact, the virtual transformation of the information Center is generally the last two phases merged into the Information Center unified operation and maintenance management platform, but does not necessarily provide cloud services, therefore, can not be called the strict sense of private cloud.) In this process, the resource virtualization is the key, because only the resources are virtualized management, can talk about ...

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...

The European Atomic Energy Research Institute (CERN), founded in 1954, is the world's largest particle physics research center. CERN, with its powerful computing power, has been providing a solid guarantee for more than 17,000 researchers worldwide to work together to crack down on the mysteries of matter and the universe in 270 research centers across 48 countries. To further accelerate research, CERN has started building the LHC, the world's largest Hadron Collider. The LHC is located in the vicinity of Switzerland and France near the border area of 100 meters underground, around 27 km of the ring tunnel.
