There are four cloud deployment models: public clouds, private clouds, community clouds, and hybrid clouds. Each cloud deployment model satisfies different organizational needs, so it’s important that you choose a model that will satisfy the needs of your organization. Perhaps even more important is the fact that each cloud deployment model has a different value proposition and different costs associated with it. Therefore, in many cases, your choice of a cloud deployment model may simply come down to money. In any case, to be able to make an informed decision, you need to be aware of the characteristics of each environment.
