Private Cloud: A private cloud, also known as internal or corporate cloud, is a cloud infrastructure that a single organization operates solely. The organization can implement the private cloud within a corporate firewall. Organizations deploy private cloud infrastructures to retain full control over corporate data.
Public Cloud: In this model, the provider makes services such as applications, servers, and data storage available to the public over the Internet. In this model, the cloud provider is liable for the creation and constant maintenance of the public cloud and its IT resources.
Community Cloud: It is a multi-tenant infrastructure shared among organizations from a specific community with common computing concerns such as security, regulatory compliance, performance requirements, and jurisdiction.
Hybrid Cloud: It is a cloud environment comprised of two or more clouds (private, public, or community) that remain unique entities but bound together for offering the benefits of multiple deployment models.
