- Private Cloud - Operated solely for an organization
- Community Cloud - Shared by several organizations and supports a specific community that has shared concerns
- Public Cloud - Made available to the general public or a large industry group and is owned by an organization selling cloud services
- Hybrid Cloud - Composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability
