The operating system's ally: Linux will dominate the rivers and lakes

When the Finnish university student had to write down the Minix clone system Linux because of his studies, I am afraid he would not think of a revolution in the computer world. After more than a decade, Linux has touched on every aspect of life, and even doubts, will Linux become the ally of the operating system? At least for now, the trend is already obvious.

First look at the hottest and most popular cloud computing technology, behind the cloud computing is virtualization and grid technology, and virtualization and grid technology is basically the world of Linux, currently virtualized Three people: Vmware, Xen, Hyper-V, the market share of the largest Vmware and Xen are based on Linux, Hyper-V's post-development momentum remains to be seen, it is estimated that Microsoft's free market strategy will not be too bad . Now there are only two public cloud centers in China: Ningbo and Foshan cloud computing centers are based on Linux.

Dedicated areas, such as seismic simulations, weather simulations, and large-scale animation design and rendering farms in Hollywood, are basically the realm of Linux.

Secondly, it is a supercomputer cluster. In HPCC, Linux is the undisputed overlord. In the global Top500 high-performance computer system, Linux accounts for more than 90% of the total, and the rest is mainly Unix, others. Basically insignificant.

Mainframe, now said the mainframe basically refers to IBM's z system mainframe, now IBM's main push z on the mainframe OS in addition to its flagship z/OS (non-UNIX) Linux is the main one (mainly Redhat and Suse), so the Unix system that can run on the mainframe is only Linux

medium machine, medium machine refers to IBM i series medium host, now hardware and The minicomputers are merged and called Power System. The difference depends on the operating system. The operating system of the midrange is i5/OS (non-Unix) and Linux.

Minicomputers and minicomputers are more diverse. They generally refer to Unix servers based on RISC and MIPS architecture CPUs on the market. Now there are small series of IBM p series, HP Alpha and Itanium (now disappeared, HP's minicomputers are now mainly based on Intel's Itanium platform. SUN's T-series servers are based on Unix (IBM for AIX, HP for HP-UX, SUN for Solaris) and Linux. Vendors such as IBM have accelerated the transfer of small machines from Unix platforms to Linux.

Microcomputer server, commonly known as X86 or PC server, in the current three major PC server vendors: IBM, HP, DELL, operating system also has three people: Windows Server, Linux, Unix (Solaris-based In the high-end areas of 4 CPUs or more, Linux/Unix is ​​the mainstay, and Windows has a considerable share of low-end servers with less than 2 CPUs. It is worth mentioning that LAMP (Linux+Apatch+MySQL+PHP) has an absolute advantage in Web services.

In the desktop field, it goes without saying that Windows is the absolute overlord and the only weakness of Linux, the last bastion of the unified rivers and lakes. But with Ubuntu and other desktop-focused distributions and the introduction of Linux-based Google Chrium OS, and the Linux-based Andorid system's counterattack on the X86 platform, Linux's growth in the desktop space is just around the corner.

Mobile phones and portable devices, mobile phone OS now has four major blocks: Linux, Unix (iPhone

), Windows Mobile/Windows Phone, Symbian. Linux originally only used Moto. Later, Nokia introduced Meego based on Linux, and later changed to Maemo. Now with the launch of Google's Linux-based Android system, Linux is gaining momentum, and now Andorid has become the dominant player in mobile operating systems, accounting for No. 1 in smartphone mobile operating systems!

Games, Windows fans The biggest criticism of Linux is that Linux support for games is too bad, which is not surprising, most of the games on PCs are now designed for Windows. . This is not Linux's poor support for games. It can only be said that there are too few Linux games. Now Linux solutions are as long as they use Wine to be compatible with Windows games. It is said that 90% of Windows games do not run under Linux+Wine. problem. Now Linux also has a lot of native games, such as first-person shooter Nexuiz is not inferior to Windows CS. But here is just a PC game. In other game areas, Linux is not a weak one. For example, one of the TV Game's overlords, Sony's PS3 system is Yellow Dog Linux 5.0!
