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 ...

When it comes to servers, you're probably not unfamiliar. Many kinds of servers, Blade server is one of the most widely used. 　　Its birth at the beginning of the server industry has brought far-reaching impact, with the recent years of cloud computing gradually mature, blade Server service capabilities and a new level. At present, blade server has begun to be in the enterprise's IT Infrastructure integration and optimization, and virtualization is the best way to cloud computing, so we also have reason to believe that Blade server will be the future of the cloud computing platform ...

The battle for architecture between ARM and Intel processors continues. Intel x86 advanced in the industry's status is indeed unshakeable, but ARM significant power advantages, the future will obviously be more attractive. That kind of CPU is the most able to meet future needs? ARM 2011 released the Cortex-A15 processor, which uses multi-core out of order superscalar design, clocked at up to 2.5 GHz. Cortex-A15 is of great importance as it runs counter to the previous generation of ARM designs.
