  • Private cloud
  • Community cloud
  • Public cloud
  • Hybrid cloud
Private cloud- The Private Cloud allows systems and services to be accessible within an organization. It offers increased security because of its private nature.  

many corporate IT environments today could be considered private clouds in that they are designed and built by and for a single customer to support specific functions critical for the success of a single line of business.
Community cloud- The Community Cloud allows systems and services to be accessible by group of organizations.

In a community cloud model, more than one group with common and specific needs shares the cloud infrastructure. This can include environments such as a U.S. federal agency cloud with stringent security requirements, or a health and medical cloud with regulatory and policy requirements for privacy matters. There is no mandate for the infrastructure to be either on-site or off-site to qualify as a community cloud.

Public cloud- The Public Cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness, e.g., e-mail.

The public cloud deployment model is what is most often thought of as a cloud, in that it is multitenant capable and is shared by a number of customers/consumers who likely have nothing in common. Amazon, Apple, Microsoft, and Google, to name but a few, all offer public cloud services.
Hybrid cloud- hybrid cloud deployment is simply a combination of two or more of the previous deployment models with a management framework in place so that the environments appear as a single cloud, typically for the purposes of “cloud peering” or “bursting.” Expect demand for hybrid cloud solutions in environments where strong requirements for security or regulatory compliance exist alongside requirements for price and performance.
