Ubuntu9.10 brings cloud computing into the enterprise

Recently, in the IY industry, "cloud computing" has become a famous place. But what is "cloud computing "? As a matter of fact, no one knows how to go in the fog. What is cloud computing? As we all know, software operation requires support from the operating system, and the operating system is closely attached to the hardware driver. A few years ago, a genius Israeli engineer invented a way to use a set of program code "virtualized" (simulated) Hard components, let the software mistakenly think that these "virtual objects" are related hardware. As a result, an artificial virtual computing environment is created, where software runs and software is bullied.

As we all know, software operation requires support from the operating system, and the operating system is closely attached to the hardware driver. A few years ago, a genius Israeli engineer invented a way to use a set of program code "virtualized" (simulated) Hard components, let the software mistakenly think that these "virtual objects" are related hardware. As a result, an artificial virtual computing environment is created, where the software runs and the software is cheated. Such a virtual environment is called a Virtual Machine (specifically, a kernel-based Virtual Machine ). Remember, a virtual machine built on an operating system has its own virtual processor, virtual memory, various virtual boards, and so on. A high-end PC computer can enable many virtual machines so that many different programs can run simultaneously in these virtual machines. The virtual machine runs in the memory. Through the network, the virtual machine can be quickly switched and moved quickly in the computer hardware environment.

A group of servers is referred to as "Cloud ". Using Virtual Machine technology, this group of servers can be "Cloud" to form a large and large virtual computing environment. When the physical hardware of a server sends a running fault signal, the cloud management system will quickly switch it out or remind the Administrator to do so. Therefore, after a cloud computing environment is started, it can run for a long time without being damaged by some hardware devices. Everyone understands that this is extremely important.

Ubuntu 9.10 has three major versions: 1. desktop version; 2. Server version; 3. Remix for netbooks. The 9.10 server version deserves our special attention. Assume that we have a group of servers running on Ubuntu 9.10 server version. With the Eucalyptus Software Package (GNU software) attached to server 9.10, we can make it an "Cloud" server cluster. In a simple sentence, Ubuntu 9.10 brings cloud computing into the enterprise.

Within the Enterprise Firewall, we can call it "Internal cloud", or "external cloud" outside the firewall ". It can be seen that the cloud is generally referred to as an "external cloud", which is difficult and mysterious. To help enterprise network administrators make good use of the "cloud computing" technology, Canonical recently launched an online cloud computing training course to provide commercial technical support for cloud computing.

Note: Cloud Computing should have been translated into Cloud Computing. The cloud, hanging high in the sky, cannot touch people. Smog is often close to the ground and people can walk through it. I think it is preferable to translate "Cloud Computing" into "Cloud Computing. It is easy to imagine what this means when Ubuntu brings cloud computers into the enterprise computing center? Cloud computing (in fact, a group of servers) has powerful and continuous service capabilities and can withstand many service requests at the same time. The so-called "virtual desktop" launched by IBM in cooperation with the model is based on this principle. Cloud Computing supports the so-called "thin client", also known as smart terminals. I think the auto-boot U disk is also listed here. For enterprises, if they build their own cloud computing center, the company's boss only needs to send each employee a small U disk, then everything will be done. I think, in a township, a cloud computing center is built. Every farmer sends a U disk and inserts it in a country cafe. Everything is done. There is no reason for rural informatization to make money for farmers. Farmers should enjoy everything that modern civilization brings, because it is precisely what farmers provide us with all the necessities of life. Looking at the dark faces of the peasants, I felt I was a little short. I think Ubuntu should not be an empty saying for the benefit of mankind. Today, the Alpha 4 version of Ubuntu August 13 is coming soon on September 10, 9.10. In this regard, some people laugh, some people cry, the world is really wonderful.
