Case :

"ABC is one of the multinational companies in the Sultanate of Oman with more than 50,000 employees all over the world. The company deals in automobiles spare parts. The company has office at Al Rusayl area. The company has upgraded the infrastructure which includes two new buildings in Rusaly. As the new buildings are added there is a requirement of computing infrastructure. The management of the company is thinking to shift its IT infrastructure and services to a low cost and secure solution. The company has hired Mr. X as a consultant for the upgradation of IT infrastructure. Mr. XYZ has a wide experience in IT consultancy industry. He is able to propose a solution to the company requirements, to upgrade the IT environment from proprietary solutions to Open Source for the software systems while simultaneously upgrading the networking infrastructure. All staff at the company desktops, and the company wanted to link these to the network wirelessly.

The company had spedfic software requirements for different departments, nearly all of which are met and exceeded by standard Open Source software packages such as OpenOffice.org, MySQL and The Gimp. These have a huge advantage over their proprietary counterparts because the employees can also run them at home on their PCs without needing to worry about software licensing.

Mr. X has proposed a low-cost solution that fully met the objectives of the ABC company at a fraction of the cost of the Windows-based proprietary equivalent. The solution has Linux at its core with a desktop based on KDE kiosk-ised to reduce administrative complexity and cost. A crucial component of the Linux-based solution was a switch to thin-client workstations accessing software running on two central application servers. This allowed all of the existing PC hardware to be re-used without any upgrades. When the PCs boot they no longer use local hard drives, but download copies of the Linux Terminal Server software from a central server instead. Running that software, they become clients for the application servers. Instead of spending significant amounts of money on upgrading the hardware, this has prolonged the life of the workstations by several years at least (and as a consequence also reduces the load on the local landfill site). Since the workstations no longer need hard drives, their power consumption and their noise output is noticeably reduced. As discussed later, the thin-client model also slashes administration effort. The Linux-based desktop uses a range of standard applications, amongst them OpenOffice.org which provides word processing, a presentation package and a spreadsheet; all of them are able to save and import files in their native XML format whilst retaining compatibility with Microsoft formats. Quanta is used as the HTML editor, the KDE education package provides an assortment of educational software components, Scribus is the desktop publishing package and The Gimp is an excellent image manipulation tool with a wide range of capabilities.

Every employee has a personal quota for file space and printer usage. Their personal FTP space is accessible both inside and outside the company and is used to share their files between home and company. Email accounts are provided to the staff through Squirrel mail which gives a web interface very similar to Hotmail or Yahoo mail, this too is visible from home as well as from company. The shared-calendar features of Squirrel mail are also proving popular.

Overall, the project has been a resounding success. Mr. Y, one of the Director of the company commented: "I can't believe how easy it has been to move to Linux. The systems were installed and working within a week and it has been a revelation how simple and painless the process has been. I have saved thousands of riyals per year and got a brand-new ICT infrastructure at the same time." He added: "Without switching to Linux, I would have been forced to cut back on our ICT hardware and software provision. There simply wasn't the budget to upgrade to the latest versions of the software or to keep replacing suites of PCs on a three or four year cyde. Now I have no licensing costs to worry about for the Open Source parts of the solution. We shall be moving to a complete Open Source basis as quickly as is practical and hope to start working with other company's interested in this type of development to share ideas and best practice". The students have taken to the new system without any difficulty whatsoever. They much prefer it to the Windows systems they had been using before, commenting particularly on the reliability of the system and one observing that he was astonished to discover, having accidentally switched off his workstation before logging out, that KDE's session-restore facility returned him back to where he had been previously when he logged in again.

The administration overhead of the previous Windows-based classrooms had kept the company's ICT technician working twelve hours a day. The new system has greatly reduced this workload. The director said "Significant amount of additional work that will arise as a result of our new status would have made his job impossible had we remained with our Windows based network, and we would have been looking to increase our technician staffing to cope. This would have been another significant ongoing cost which we now feel we can avoid. This funding can now be better spent on developing materials for the employees to use rather than on keeping the network running."

Questions:

1. Do you think implementing the low cost solution proposed by Mr. X was a success? If "yes" provide appropriate justification or if "no" then provide appropriate reasons.

2. Discuss how the low cost solution can be further enhanced with some more services.

3. How selecting the Linux based solution technically helped the company.

4. Critically evaluate the security issue and challenges that you feel still in proposed solution. S. Considering the above case study do you think single technician could now administer something between three and five separate company if they all used cloud based systems
like those in place at ABC Company.
