How cloud is becoming the major IT infrastructure?

More detail can be found in a 2009 cloud computing research study by IBM Market Insights. The study said 77% of companies were interested in cloud computing for the cost savings (hardware, software licenses, labor costs, IT support, and outside maintenance costs). The time/value ratio for simplifying upgrades, installations, and scaling IT was a close second, noted by 70% of those surveyed.

According to a 2009 study done by Ziff Davis Enterprise Research more companies are evaluating cloud computing than ANY other emerging technology and more than twice as many companies are using it than last year.
