TCS, Infosys betting big on Cloud computing
Till a few years ago, the IT industry had three categories of companies - hardware companies, software product companies and IT services companies. If an organisation wanted to computerise a certain function such as payroll, it first bought the hardware, then the licences for the software, and finally hired the services of a third company to customise and implement the application according to its specifications. Naturally, it was an expensive and time-consuming process and managements debated on whether they had the budgets for it before embarking on such an exercise.
