We are adding more information about clouds in general. Below are some definitions for better understanding IaaS concepts.

Public Cloud. The cloud infrastructure is made available to the general public or a large
industry group and is owned by an organization selling cloud services.

Private Cloud. The cloud infrastructure is operated solely for a single organization. It
may be managed by the organization or a third party, and may exist on-premises or off premises.

Community Cloud. This cloud type is an infrastructure shared by several organizations and
supports a specific community that has shared concerns (e.g., mission, security
requirements, policy, or compliance considerations). It may be managed by the
organizations or a third party and may exist on-premises or off-premises.

Hybrid Cloud consists of two or more infrastructure types that can be clouds (private,
community, or public) or cloud and physical. Both types are bound together to provide single scalable infrastructure.
