This document discusses moving to a zero IT infrastructure footprint by transitioning to cloud computing and hosted services. It describes how organizations can evaluate their current data center and IT infrastructure, assess options for colocation, hosted private and public clouds, and develop a roadmap to transition workloads. The roadmap involves assessing the organization, applications, costs, risks and conducting a phased approach to planning, executing the transition, and decommissioning existing infrastructure. The goal is to focus IT on data, applications and services rather than physical infrastructure management.
