Virtualization

Cloud computing is the most advanced and hot information processing technology in the world. It depends on the network. If it was 20 years ago, no one would consider cloud computing at all, because the network was too slow, and it was knocked back every time.

Cloud computing has been hot in recent times, and the topic of it is overwhelming. And the progress of cloud computing has also risen from the previous conceptual speculation to the product stage, and the discussion about the impact of cloud computing on various industries has become increasingly deep.

Grid computing is a computer science that studies how to divide a problem that requires a very large amount of computational power into many small parts, then distributes those parts to many computers for processing, and finally combines these calculations to get the final result.

The essence of technology lies in the accumulation of accumulation. The virtualization, RESTFull API, and distributed concepts of the past have undergone earth-shaking changes over the past decade.

At different stages of the cloud computing experience, whether it is a private cloud, a public cloud or a hybrid cloud, it will face the key issues of cloud data center construction: how to improve the resource utilization of the data center, how to reduce the overall cost, optimize management,etc.

Virtualization technology breaks the dependence of the operating system and hardware, manages the operating system and applications as a single individual, strong security and fault isolation, and the virtual machine is independent of the hardware and can run on any hardware.

Server virtualization technology should be traced to the IBM mainframe virtualization z / VM. Today's content covers CPU virtualization, memory virtualization, IO virtualization, and GPU virtualization. Technical in-depth popular science articles.

This article takes you through virtualization, enumerates common virtualization software and virtualization architectures, and finally makes an introduction to kvm.

With the popularity of virtualization technology, five mainstream virtualization technologies have gradually emerged. The five virtualization technologies are: CPU virtualization, network virtualization, server virtualization, storage virtualization, and application virtualization.

Virtualization is a broad term. In terms of computers, computer components (hardware, software, and operating) systems are usually run on virtual basic equipment, not real equipment. Here mainly explains virtualization in cloud computing.

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.
