About Bhubaneswar, it says:

Once famed for its Sun Temple, the capital of Orissa is fast emerging as a major player in the outsourcing industry. The city accounts for almost all of the IT revenue of Orissa and is one of the fastest growing regions in India in this sector.

The city is home to more than 30 engineering colleges. Although Orissa has a planned investment of $90 billion for the IT sector, the road to success is fraught with hindrances. Land acquisitions for some of these projects have been opposed by the local people as well as by environmentalists.
