Well, a lot more is said about Infosys also known as Infy. Mysore has one of Infosys's largest campus, rather the largest such facility in the world.
This sprawling campus located on the outskirts of Mysore city is boasted as the "World's Largest Corporate Training Center", with capacity to accommodate 14,000 trainees at any time.
What more, a group of buildings are built in such a fashion you can read its layout as INFOSYS from space! Go to Google map or Google earth and see the Infosys campus in Mysore.
True to their ethos of large scales and the craving for distinction, Infosys has taken their brand building to a different space altogether.
By the way the Infosys Mysore campus is located some 8km (5 miles) northwest from Mysore City center. Take an auto-rickshaw or even catch one of those city buses ( Mysore Bus stand ) . If you are driving, take the Outer Ring Road or Hunsur Road.
If you are flying into Bangalore, take the FlyBus to Mysore. These are volvo bus services directly from Bangalore airport to Mysore city.
