European adoption of software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) is growing strongly. In some categories, they have reached the mainstream, while in others they are gaining market. The diversity in business, culture, and languages means that U.S. vendors will not succeed if they copy their U.S. strategies in Europe. Also, many European vendors are building out their own services and capturing market share. IDC's European Public Cloud Services: SaaS, PaaS and IaaS research will provide insightful and actionable understanding of the public cloud services market in Europe. The service helps product, marketing, and strategic planning executives develop successful business strategies and gain competitive insight. The service examines the market in three categories — SaaS, PaaS, and IaaS — as well as their subcategories. It will also inform vendors of "conventional" IT products and services on their strategies in the public cloud.
