3 The Hype! Gartner - Cloud computing revenue will soar faster than expected and will exceed $150 billion within five years. Forrester - Cloud-Based Email Is Often Cheaper Than On-Premise Email Vivek Kundra, CTO of Obama Government: “Growing adoption of cloud computing could improve data sharing and promote collaboration among federal, state and local governments.” E.g: fedbizopps.gov Merrill Lynch: “By 2011 the volume of cloud computing market opportunity would amount to $160bn , including $95bn in business and productivity apps (email, office, CRM, etc.) and $65bn in online advertising.” IDC: “Spending on IT cloud services will triple in the next 5 years, reaching $42 billion and capturing 25% of IT spending growth in 2012.” Sources: http://www.infosysblogs.com/cloudcomputing/2009/08/the_cloud_computing_quotes.htm and http://www.mytestbox.com

The deployment time is really what impressed us. It's just shy of instantaneous."
