Cloud Summit 2012 was focused on how cloud computing is disrupting businesses and driving down costs. The document discusses how cloud computing allows for scale which reduces hardware, maintenance, support, and facility costs. It also notes that data volumes are growing exponentially and that enterprise value is shifting to focus more on data and applications rather than infrastructure. Cloud computing is seen as an opportunity for Indian industries to collaborate and disrupt through areas like healthcare, tourism, education, retail, and logistics.
