This IDC study forecasts revenue growth from public IT cloud services through 2014, segmented by five functional categories within eight regions/countries. The forecast data, driven by IDC's key assumptions for public IT cloud services development and adoption, lead to this document's key conclusions regarding cloud offerings' revenue and growth impacts on the IT industry, customer adoption shifts among the five IT cloud services categories, and shifting adoption patterns among the eight regions/countries.
According to IDC Chief Analyst Frank Gens, "Our forecast shows that public IT cloud services are currently 'crossing the chasm,' with modest revenue but very fast growth. Cloud services will be a major contributor to IT industry growth by 2014. IDC sees 2010–2014 as important years for IT suppliers to position themselves to capture that growth."
