Scenario 3: Pusat Teknologi Maklumat (PTMK). is looking to swap the current IMS system. Main reason for this activity is to reduce the cost of maintaining application licenses. The reduction of cost does not mean that the operating system has to be with only basic features. The OS must be reliable especially to handle to large traffic every day. PTMK is open to proprietary or open source OS as long as the cost is low & OS is reliable
Brief History. The operating suppose we choose to do is Linux. It as first written by Linus Torvalds, who started in 1991 with the idea of learning the capabilities of an 80386 processor for task switching.
Linus Torvalds invented Linux itself. In 1991, Torvalds was a student at the University of Helsinki in Finland where he had been using Minix, a non-free Unix-like system, and began writing his own kernel. He started by developing device drivers and hard-drive access, and by September had a basic design that he called Version 0.01. This kernel, which is called Linux, was afterwards combined with the GNU system to produce a complete free operating system. On October 5th, 1991, Torvalds sent a posting to the comp.os.minix newsgroup announcing the release of Version 0.02, a basic version that still needed Minix to operate, but which attracted considerable interest nevertheless. The kernel was then rapidly improved by Torvalds and a growing number of volunteers communicating over the Internet, and by December 19th a functional, stand-alone Unix-like Linux system was released as Version 0.11. On January 5, 1992, Linux Version 0.12 was released, an improved, stable kernel. The next release was called Version 0.95, to reflect the fact that it was becoming a full-featured system. After that Linux became an underground phenomenon, with a growing group of distributed programmers that continue to debug, develop, and enhance the source code baseline to this day.

It was originally hosted using the Minix operating system.
Improvements through out it has made it what it is today. It is also a leading operating system on servers and other big iron systems such as mainframe computers and supercomputers for more than 90% of today's top 500 supercomputers run some variant of Linux, including the 10 fastest. Even though Linux is rarely used for home use, it is usually abundant in offices and companies because of its advantages.

Significant milestone achievement until today
Linux systems are used in every domain, from embedded systems to supercomputers. Have secured a place in server installations often using the popular LAMP application stack. Linux have been widely used in home and enterprise, as well as in education nowadays. Nearly 60% of all websites on the Internet are run using an Open Source program named "Apache." Most often, it's run on Linux. If you've ever surfed the web, you've (indirectly) used Linux!
Linux is based on Unix, an operating system developed in the 1970s and which is still used heavily today, especially to run the Internet. Linux is used both to run parts of the Internet, as well as to run small and large networks in coporations, offices and homes.
Since Linux is stable, secure and robust, it's perfect for storing huge databases of information. A large collection of inexpensive PCs running Linux can be just as powerful as a mainframe computer, but at a tenth of the cost. The city of Munich, Germany has "chosen to migrate its 14,000 desktops to a free Linux distribution, rather than a commercial version of the open source operating system" according to a 2005 ZD Net report.
Linux has spread rapidly throughout Spain since 2002, when the government of Extremadura actually created its own cutomized Linux distribution (called LinEx) based on Debian, using GNOME as its "default desktop environment." Since then, the government "gave away the product CDs at every opportunity.
The Commercial Bank of China and the state-owned Industrial decided to roll out Linux in all of its 20 000 retail branches.

Justification & reason for choosing Linux. Advantages of LINUX. Low in cost. You don’t need to spend time and money in order to obtain licenses since linux and much of its software come with the GNU General Public License. It is suitable operating systems for Scenario 3 as it need a low cost one. It doesn’t freeze up or slow down over time due to memory leaks and such. Continuous up-times of hundreds of days (up to a year or more) are not uncommon. Linux provides persistent high performance on workstations and on networks. It can handle unusually large numbers of users simultaneously, and can make old computers sufficiently responsive to be useful again. Excellent user interface and usability. Linux continues work well even when the hard disk is almost full. Linux is one of the most secure operating systems. It runs all common Unix software packages and can process all common file formats. The large number of Linux distributions gives you a choice. Each distribution is developed and supported by a different organization. Linux is one of the open OS as it will very suitable used in PTMK.
