Infosys Global IT Service Provider Upgrades Operating System, Enhances Performance

Infosys Technologies, one of India's largest IT companies with operations in 75 cities in 31 countries, became an early adopter of the Windows 7 Enterprise operating system. Based on a successful pilot on 500 desktops and portable computers, Infosys has rolled out Windows 7 to 41,000 computers, and plans to upgrade the operating system on the majority of its computers by June 2011. The company is using Microsoft Deployment Toolkit 2010 to deploy Windows 7, and has migrated many of its web applications to Windows Internet Explorer 8. It has used Microsoft Application Virtualization to virtualize training materials at its Global Education Center at Mysore. The company expects to benefit from improved IT management, greater employee productivity, power-saving capabilities, and more efficient training processes.

Founded in 1981, Infosys Technologies is a multinational IT services company headquartered in Bangalore, India. It is a global leader in next-generation IT and consulting with annual revenues of U.S.$4.8 billion.

Infosys defines, designs, and delivers technology-enabled business solutions for Global 2000 companies. Fortune magazine identified Infosys among the top companies that inspire, nurture, and empower a new generation of global leaders.

The company has a presence in 75 major cities in 31 countries, and hosts development centers in India, China, Australia, Czech Republic, Poland, United Kingdom, Canada, and Japan with more than 125,000 employees. Infosys is known for being quick to adopt the latest technology to enhance its growth and productivity.

Infosys has more than 125,000 desktop computers and portable computers. Of the 105,000 Microsoft client operating system–qualified desktops, approximately 57,000 have been running the Windows XP operating system and 8,000 have been running Windows Vista. The company wanted to adopt the Windows 7 Enterprise operating system to enable faster and improved performance. Infosys needed to enhance productivity and offer employees opportunities for improved collaboration with colleagues around the world. Also, because it was supporting so many computers, it wanted to reduce power consumption, an area of large expense.

* With Windows 7 Enterprise, we expect to improve user productivity, enhance security, and progress to the next step in our green IT initiative. *

“We always implement the latest technologies,” says Muralikrishna, Senior Vice President and Head of the Computers and Communication Division at Infosys Technologies. “This keeps us ahead of the curve with a more structured, secure, and manageable IT environment.”

Infosys has long been an early adopter of the newest Microsoft technologies and solutions. When given the opportunity to participate in the Windows 7 First Wave Early Adoption Program, the company was eager to test the operating system.

During the pilot phase in 2009, the company installed Windows 7 Enterprise on 500 computers and conducted compatibility tests on internal, third-party, and line-of-business applications. It also tested memory usage, overall performance, and CPU utilization.

Test users provided management with overwhelmingly positive feedback about Windows 7. Employees were impressed by the operating system’s excellent performance, quick startup and shutdown time, and memory features.

Infosys put Windows 7 into the same deployment environment that it used for Windows Vista for additional testing on application compatibility and response time. “The results were excellent,” says K. Purushotham, Associate Vice President at Infosys. “We witnessed a high traction rate with Windows 7. Users wanted to migrate to the new operating system.” Based on the success of the tests, the company deployed Windows 7 on 41,000 additional computers starting in early 2010.

Because the company had already performed extensive application compatibility tests during its deployment of Windows Vista, it meant that Infosys had to test only incremental applications for compatibility. “We had deployed Windows Vista on approximately 8,000 computers,” says K. Purushotham. “Because of the compatibility tests that we already conducted, it was a considerably easier and simpler task to implement Windows 7.”

Infosys is using Microsoft Deployment Toolkit 2010 to deploy Windows 7 and manage its computer environment. It plans to upgrade 70 percent of its desktop and portable computers by June 2011. Ideally, Infosys would like to have 100 percent of its computers running Windows 7. Because some of its projects and customers still use previous versions of the Windows operating system, Infosys will continue to use Windows XP and Windows Vista on the remaining computers.

The company employs Windows 7 to reduce power consumption because the operating system works with the latest hardware power-management capabilities and does a better job of managing how application processes use the processor.

Infosys also upgraded from Internet Explorer 6 to Windows Internet Explorer 8 as part of its Windows 7 deployment. With the help of Microsoft, it has rectified 40 web applications for compatibility and migrated them to Internet Explorer 8.

* Windows 7 drastically boosts performance while consuming fewer resources. It also makes work easier with its attractive and richer interface, and offers more functionality than the previous operating systems. *

Infosys has also used the virtualization features that work with Windows 7. The Infosys Global Education Center in Mysore, India, a 337-acre campus that can train as many as 14,000 employees at any given time, was spending too much time readying desktop PCs for trainings. The company had to prepare for a variety of sessions for employees ranging from Microsoft .NET tutorials to Java instruction. The team was obliged to format PCs and install new training materials for each session—with three to four trainings scheduled each week. When the company looked at Microsoft Desktop Optimization Pack (MDOP)—a suite of six products available as a subscription for Software Assurance customers, it realized it could employ Microsoft Application Virtualization (App-V) to virtualize the training applications. The company has now deployed App-V on 20,000 computers.

By upgrading to Windows 7, Infosys reduces IT management tasks, improves employee productivity, supports its green IT initiative, and takes advantage of desktop virtualization. “With Windows 7, we expect to improve user productivity, enhance security, and progress to the next step in our green IT initiative,” says Muralikrishna. “We expect to realize a huge savings once we have completed deployment.”

Simplifies IT Management
“Windows 7 has made life easier,” says Muralikrishna. “It makes my work more effortless as it reduces background activities, which results in better power and processor management.”

Enhances Employee Productivity
Employees have reported satisfaction with the user interface improvements in Windows 7, which raises the comfort level of users and indirectly improves productivity. “Windows 7 drastically boosts performance while consuming fewer resources,” says K. Purushotham. “It also makes work easier with its attractive and richer interface, and offers more functionality than the previous operating systems.”

Saves Power
After the successful pilot, Infosys management became aware of the outstanding power-saving capabilities of Windows 7. The operating system’s faster startup and resume time increases battery life, which increases employee productivity. With the power management options available in Windows 7, Infosys can move forward in its green IT initiative.

Enables Desktop Virtualization
By using App-V, Infosys has made it possible for employees to easily switch between different training materials. At least 25,000 users benefit from this implementation because it removes the burden during training sessions of formatting PCs frequently and installing and uninstalling the software required for training.

“Infosys is one of the oldest and most trusted of Microsoft partners,” says Muralikrishna. “Microsoft products are an integral part of our organization. We look forward to laying another robust and strong foundation by using Windows 7.”
