With the upcoming upgrade of the company’s computer systems, The Business Company is offered the perfect change to make a change from a Windows Operating System to a Linux Operating System. With Linux offering more security, the same software features as Windows, and a cheaper licensing fee, the company could decrease system downtime and system cost. A switch of operating system, though drastic, should be pursued as more and more companies are switching everyday, though the only hindrance is the existing end user. If the employees are unwilling to make the effort to adapt to the change, the benefits will never be realized. 3 Introduction. For the upcoming upgrade of The Business Company’s computer systems a decision needs to be made on what operating system the company wishes to use on the new machines. Instead of normally choosing a Windows-based OS like Windows 2000 or Windows XP, the company should consider a Linux-based OS as an alternative. One of the leading Linux Operating Systems gaining ground in the PC Market is Red Hat Enterprise Linux, which is specifically geared towards large corporate environments. With growing security concerns and the rising costs of Windows licenses, many companies like IBM and Novell have already made the switch. This report is based on the feasibility of the company switching to Red Hat Enterprise Linux for the new computers and is meant to inform upper management on the appropriate course of action to take. The two main sources of information for this report are the website for Red Hat Enterprise Linux and an article from LinuxQuestions.org entitled “Switching to Linux from Windows.” The topics covered in this report are how easy this changeover can be and how it will benefit the company. 4 Collected Data. There are several areas of concern where a switch from Windows to Linux would be beneficial; security, ease of use, and cost. The basis of the whole Linux operating system was built around the idea of security and a Microsoft computer has yet to be as secure as a Linux computer. With Red Hat Enterprise Linux you get weekly security updates for your OS, just like Windows, to keep up with changing computer threats. Also, the number of hackers and viruses targeted towards Linux Networks and Systems are no where near the number targeted towards Windows Systems. Since Windows is running on about 97% of the computers in the world, about 97% of the viruses and worms created are targeted against and exploit Windows. When many people hear Linux, the thought of learning a new computer environment initially frightens them away. However, the recent versions of Linux are just as user friendly as any GUI* (all terms followed by an asterisk are defined in the glossary, pg. 8.) environment, and their ease of use increases with each update. The Red Hat Enterprise distribution comes with many features similar to Windows along with many unique features and an array of applications allowing the ability to continue to work with and edit all of the existing data on the company computers and networks. The Red Hat desktop is set up very similar to the Windows desktop and is very easy to become accustomed to. Not only does it feel similar, but it also adds some new functionality that Windows lacks like the Dock Bar at the bottom of the screen instead of the traditional windows task bar. The Dock bar can be fitted with custom modules to display all sorts of things. Some modules include a clock, world clock, weather, 5 calendar, e-mail notification, desktop switcher, website update notification, important company notifications, and any custom module the company may need to create. The Enterprise distribution also comes fully loaded with open source* applications for editing all sorts of documents. For images, Red Hat provides GIMP*, which is a very robust image editor very similar to Adobe Photoshop. For working with existing Microsoft Office documents, Red Hat offers the OpenOffice suite, which comes with separate programs to edit and create Word documents, Excel spreadsheets, and PowerPoint Presentations. Finally, for the software developers, the Enterprise distribution has the full GNU GCC* compiler along with an array of debugging and test editing programs. Not only is Red hat Enterprise Linux user friendly on the client side, it is also user friendly on the IT Support side since Linux was built around networkability. Many client side issues can be fixed remotely by IT staff. The Enterprise Server Distribution also comes with many open source server applications that can be used, including the Apache Web Server, MySQL Database Server, and an E-mail Server. There is no open-source alternative to Oracle* or SAP* servers, but if you already have an Oracle or SAP license you can obtain the Linux version of the software to run on any Linux Server. The final area of concern is the cost benefit from choosing a Red Hat Enterprise Linux license over a Windows 2003 license. Both companies offer completely different pricing schemes, so their standard packages will be compared. Microsoft’s current price for a 20 computer license is $2,761 where Red Hat Enterprise’s price for a 50 computer license is $3500. The cost difference can be easily seen, and with a full assessment from the IT department on the configurations we need, the cost could drop even more. 6 Conclusion. From all of the findings, a switch to Linux with improve system security, will still allow easy use and access of all company data, and will save the company on operating system licensing fees. The company also stands to save money on software licensing fees since the Red Hat Linux Enterprise distribution comes with many free, open source equivalents of traditionally used Windows office software. This report shows that the switch from Windows to Linux would be very easy to accomplish physically. The only hindrance is the ability of the current employees to adapt to the Linux environment. It is very quick and easy to learn the Linux environment, but not many employees may be willing to take the time or give the effort to support this drastic change. As this report summarizes, the change from a Windows OS to a Linux OS would be beneficial and is recommended for the company to pursue, but a case study should be performed on how well it would be accepted by the employees. The change should only me abandoned if the employees will fail to make the small effort to adjust to the new and different environment of Linux. 7 Glossary.
