European adoption of software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) is growing strongly. In an increasing number of categories, cloud services have become mainstream, while in others they are gaining market share against traditional on-premise alternatives. The diversity in business, culture, and languages in Europe means that U.S. vendors will not succeed if they simply copy their U.S. strategies in their European operations. At the same time, European vendors are building out their own cloud services and capturing market share. IDC's European Public Cloud: SaaS, PaaS and IaaS research provides an insightful and actionable understanding of the public cloud services market in Europe. The service helps product, marketing, and strategic planning executives to 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.
