Use of the public cloud could increase twice as fast as the market anticipates—up to a 50% CAGR in the next three years. Our AlphaWise evidence is based on the first cloud migration survey of IT managers across the US, Europe and Asia-Pacific: those using the cloud are expected to rise from 28% to 51% in three years, and the portion of their workload running in the cloud may more than double. Seventeen analysts from seven industries discuss how the shift away from on-premises hardware will affect the IT universe and identify eight companies positioned to capture the cloud.
