A cloud deployment model represents a specific type of cloud environment, primarily distinguished by ownership and size.

There are four common deployment models :

• Public Cloud - A public cloud is a publically accessible cloud environment owned by a third-party cloud provider.
• Community Cloud - A community cloud is similar to a public cloud except that its access is limited to a specific community of cloud consumers.
• Private Cloud - A private cloud is owned by a single organization.
• Hybrid Cloud - A hybrid cloud is a cloud environment of two or more different cloud deployment models.

Variations of these models can also exist.
