In 2013, Forrester saw a spike in interest in hosted private cloud — adoption nearly doubled within a single year. Hosted private cloud remains one of the least understood core cloud deployment types. Vendors and enterprises alike still struggle with the basic definition and key differentiators of virtual private and public cloud environments. One of the most common requests Forrester receives from our infrastructure and operations (I&O) clients is for baseline adoption data for hosted private cloud to inform their cloud strategies and compare their progress to that of their peers. This report showcases the following North American and European hosted private cloud data: 1) adoption relative to other deployment types; 2) adoption by country; 3) adoption relative to previous years; 4) top concerns; and 5) top drivers. The data in this report is powered by Forrester's Forrsights Hardware Survey, Q3 2013, which was fielded to 2,306 hardware decision-makers in North America and Europe. I&O executives should use this data — along with Forrester's cloud computing playbook — to discover, plan, act, and optimize their hosted private cloud initiatives.
