Sizing The Cloud from Forrester

Understanding And Quantifying The Future Of Cloud Computing by Stefan Ried, Ph.D., Holger Kisker, Ph.D.


Building a solid cloud computing strategy and business plan requires insights into the future market size and growth dynamics of this still complex market. In this report, Forrester provides a global market forecast for cloud computing and its various submarkets in this space. Based on Forrester's previously published cloud market taxonomy, we provide forecasts and information on 12 distinct market segments of cloud computing for the 10 years from 2010 to 2020. Note that, in this report, we forecast shifts in the usage patterns of infrastructure, platform software, and business applications. Readers should fully understand the definitions of each segment listed and the expected patterns of change to draw the proper conclusions from this forecast. Vendor strategists can use this report to check their own assumptions, build their cloud business plan on solid numbers, and map their current and future portfolio to the defined market segments of the taxonomy.
