India is the second largest internet market in the world, with 658 million users on line and another two 50 million joining in by 20 25. For companies like facebook, twitter and linked in, this is an opportunity like no other. Indian law makers would prefer these foreign companies build those data centres in india or store data locally. But if data localization rules were implemented, it would make it a tad bit difficult for companies to use and process data belonging to indians.
