I'm not going to give you a long-winded look at four examples.
1, the hottest and most popular cloud computing technology behind is the virtualization and grid technology, while the 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, The post-show stamina of hyper-V remains to be seen.
2, supercomputer cluster, in HPCC, Linux is undisputed overlord, in the global Top500 high-performance computer systems, Linux accounted for more than 90% of the share, the rest is mainly UNIX, the other is basically insignificant.
3, desktop field, needless to say, Windows is the absolute overlord, Linux is the only one weak spot, unified the last bastion of the lake. But with the desktop-focused release of Ubuntu and the launch of the Linux-based Google Chrium OS, and the Andorid of Linux-based systems on the X86 platform, the growth of Linux in the desktop world is around the corner.
4, mobile phones and portable devices, the phone's OS now has four blocks: Linux, Unix (iPhone), Windows mobile/windows Phone,symbian. Linux was originally only Moto-dominated, and later Nokia introduced Linux-based Meego, and then changed to Maemo. Now with the launch of Google Linux-based Android, Linux is in the limelight, now Andorid has become the dominant mobile operating system, accounting for the smartphone mobile operating system no.1!
