More stable than Windows and Linux - this is the universal impression of Unix. NHN Japan, operating game website, "Hangame Japan", using the corresponding type of OS according to different purposes. The company's Zo Na Yu (network and system room long) evaluation said: "Even if the load is added, UNIX will not slow down. Source code management is also very safe and reliable." Look at the verification data implemented by the Nomura Comprehensive Research ("" IT Solutions New Area "No. 5 Issue 2004), discovery even if the number of tasks that increases simultaneously, UNIX's calculation capacity will not decline. Even if the large host is replaced with UNIX, it also gives people a stable feel. "Overseas has continued to replace large hosts into UNIX. This movement has finally appeared in Japan. Recent examples include Sony Marketing Company feeling that the application software is about to expire, and the IBM large host is replaced with UNIX. KANAMOTO, engaged in the construction machinery leased business, has changed Fujitsu larger host to UNIX. But the environment where UNIX is still very serious. More and more worrying it is "which step will come in the future." Gradually away from the environment in which UNIX is located, the author feels in an interview with business users. Large Engineering Construction Company Japan COMSYS has previous previously used Solaris as the standard OS within the company, but this year decided to replace Linux. This is because I am worried that the number of applications is increasing. Every time you have to purchase the server, this cost is too big. "Review the case analysis of the" Nikkei System Construction ", easy to form a cluster structure, to the server Single-machine stability requires not too high WEB server almost all selected Windows or Linux. As for a short-time regular business server, there seems to be the same trend. Even a large system AP / DB server of mission critical, recently swallowed by Windows and Linux. For example, as a large ERP "SAP R / 3" execution OS, many users are selected for Windows. As mentioned earlier, Kanamoto's Xiong Gu Hao (executive director, minister of information system) asked: "The next platform of the backbone system will be Linux". The next replacement will be 5 years later. NEC Deputy President Sichuan Village is full of confidence in Linux: "Like UNIX 10 years ago. It is expected that Linux will grow at a rate of 25% in the year. We not only increase technicians, but also to enrich the maintenance system." "With windows / Linux gap disappears Windows and Linux can run on relatively inexpensive IA servers, and Windows also has a cost advantage of such a technician. On the contrary, its weakness is the deep-rooted "stability is not confident." Microsoft has tried to eliminate the impression of "It's prone to have insufficient memory" from the Windows NT era. Linux has problems such as "lack of log" when Kernel PANIC, compared to commercial UNIX, is still unable to maintain the stable operation of the trunk system. In current cases, UNIX can lead one to two steps in terms of stability. But it is difficult to continue to maintain the same leading advantage after five years. Look at the new product trends of the server manufacturer, it will find that there is no gap between the OS at the hardware level. For example, NEC's UNIX server "NX7700i" and Windows Server "Express5800 / 1000" is only different, and the power supplies and chipsets are basically using the same thing. Fujitsu will serve the main IA server in 2005. This is a server product that will originate from a large host's technology to the Windows / Linux server to enter key task applications. Although mainly in the eye is the reliability of hardware such as chipset, it seems that there is no feedback from OS. Linux has begun to show results slowly.
