Cloud computing, with its substantial benefits, has thoroughly changed the technology and business landscape. Through cloud, enterprises of all sizes can more easily optimize their IT investment and achieve economies of scale, cost savings and business innovation. Recent surveys bear out these benefits. According to one survey, organizations that have deployed cloud on a broad scale report nearly double the revenue and gross profit compared to organizations that are more cautious about cloud adoption. Another survey reports that 64 percent of chief information officers (CIOs) consider cloud a crucial technology for customer engagement.
