Cloud computing is all the rage. Information technology is changing rapidly, and now forms an invisible layer that increasingly touches every aspect of our lives. Power grids, traffic control, healthcare, water supplies, food and energy, along with most of the world's financial transactions, now depend on information technology. Cloud computing is massively scalable, provides a superior user experience, and is characterized by new, internet-driven economics. This paper focuses upon the needs of IT i.e., a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software and can significantly reduce IT costs & complexities while improving workload optimization and service delivery.
