Education: ELCOT rolls out Linux to 30k desktops and 1880 servers in Tamil Nadu schools
The Electronics Corporation of Tamil Nadu helps Govt. of Tamil Nadu in procuring hardware, software, and in meeting the state's various e-governance objectives. That's a pretty enormous task, given that most govt. projects are pretty large scale, involving very high investments. One such ambitious project is migrating all servers and desktops in in Tamil Nadu's schools to Linux. That's about 1880 servers and over 30,000 desktops. So far, the 1880 servers have been migrated, and 3000 new Linux based desktops have been supplied. These are all running on various SUSE Linux distros. The biggest benefit of moving to Linux, according to ELCOT's MD, C. Umashankar-no worrying about viruses any more!
The company has worked with teachers to design applications for the Linux based systems, like adding a Tamil voice-over to their computer-based training software, dual-language instruction manuals, etc. Other benefits of moving to Linux include the ability to experiment with different applications without making big investments. That's why, ELCOT has designed a suite of applications that deliver all functionality required by teachers.
Insurance: ING Life, India migrates its desktop fleet from Windows to Linux
The life insurance giant replaced Windows and MS Office on its desktops with SUSE Linux Enterprise Desktop, giving it significant cost savings over the life of each machine.

Insurance: National Insurance Company migrated 1000+ servers from UNIX to Linux
One of the largest and oldest general insurance companies in India, NIA has more than 200 types of policies and 1,000+ branches across the country. With increasing competition, the company needed an IT infrastructure that could match the speed and scale of its functioning. Till about 2000, the company was totally dependent on a proprietary IT infrastructure running on SCO UNIX. Once SCO stopped its support, the company moved over to Linux, choosing RedHat's Enterprise Linux OS as the replacement. It started with a corporate mailing server with an anti-virus and LDAP solution and centralized application settings, user profiles, group data, policies, and access control information into a network-based registry. Over 6,000 users are currently authenticated using this solution.
Later the company also migrated a critical insurance application from UNIX and Oracle 8.0.4 to Oracle 9i on Red Hat Enterprise Linux. In fact, the company has successfully migrated 1000+ servers to Linux in just three months, and is currently deploying a core insurance application at a speed of 50 offices per week.
Education: HRD Ministry, Govt. of India introduces Rs 1500 tablet that runs on Linux
The Sakshat tablet has been in the news for a while now, because of its extremely low cost of just Rs. 1,500. The HRD ministry of govt. of India plans to distribute this tablet to 504 universities and 25,000 colleges across the country. Conceptualized by great brains at IISc, Bangalore, and the IITs (Kanpur, Kharagpur, Chennai, and Mumbai), the tablet is likely to create a huge impact on the cost of portable computing devices in the country.
Services Industry: Just Dial powers its mission-critical intranet and extranet applications on Red Hat Enterprise Linux
Just Dial doesn't need an introduction for most Indian consumers. It's India's top-ranking local search engine, which bridges the gap between buyers and sellers across 240 cities in India, and several other countries in the world. The local search is available on phone, web, WAP and SMS. It reaches out to 25 million unique users across the country. Obviously, such a large user base and so many communication channels require a good IT infrastructure to function efficiently. The company was earlier using an archaic, DOS-based system built on FoxPro and running on a client/server model. It decided to move to an open, web-based architecture. The company chose LAMP (Linux – Apache – MySQL – PHP) for both its intranet and the extranet, and used C programming for optimizing their algorithms. The Linux platform is provided by Red Hat. With the move, the company doesn't worry about virus attacks or stack overflows. Though the company's server count has increased by more than 20 times, the company didn't have to increase the team size to manage it. Business has increased from 80,000 calls per day to over 250,000 calls.
Services Industry: TaxSpanner, the best income tax intermediary runs its business on Linux
In just four years of its existence, TaxSpanner has become the largest player in the income tax filing space in India. The group set up its IT infrastructure on LAMP architecture, with the exception that it uses PostgreSQL, and Python instead of MySQL and PHP.

Mobility: Google's Android runs on Linux
Android OS is perhaps the biggest success story of Linux in the embedded space. According to androidtapp.com, there are around 60,000 Android based phones being sold every day. There's an estimated 250,000 applications available for Android phones, and this will obviously grow. The huge success of Android can be solely attributed to the fact that it's open source, allowing communities across the world to develop on it. That's why, Android is running on a wide variety of mobile devices today-smartphones, tablets, netbooks, and even Google TV.
