It discusses characteristics of cloud computing including on-demand self-service, ubiquitous network access, resource pooling, rapid elasticity, and measured service. It also covers Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS) models. The document then discusses options for building a private cloud including doing it yourself using Microsoft's guidance, using a pre-validated configuration from a partner, or working with a hosting provider.
