Cloud Deployment Models: Essentially, cloud computing relates to a new way of thinking to a world in which a company’s computers, software and data is not held on a private server in a basement, but in a secure shared internet-based environment.
In a prior article defining “what is cloud computing“, we showed the 5 characteristics of cloud computing. In it, I referred to CRMHelpdesksoftware’s article on SAAS, PAAS & IAAS.
Today I explain cloud computing by detailing the 4 possible cloud deployment models.
I will subsequently addressing which one might be best for your organisation.

4 Cloud Deployment Models
Cloud Computing for Dummies: ‘Deployment models’ is a fancy IT term for saying ‘Ways to operate in the world of cloud computing’.
Depending on which of the four models you will choose, your cloud deployment could have limited private computing resources and instead give you access to large quantities of remotely accessed resources. Each deployment model presents its own set of benefits & tradeoffs in terms of how customers can control their resources, the scale, cost & availability of resources.
- Public Cloud. In this case, the cloud infrastructure is available the general public or a large industry group. It is typically owned by an organization selling cloud services.
- Private Cloud. This is a cloud deployment model that’s opposite to the private cloud in that the cloud infrastructure is operated exclusively for 1 single organization. It is still cloud computing, and may be managed by the organization or a third party and may exist on premise or off premise.
- Community Cloud. In this case, the cloud infrastructure is shared by a group of organizations called a ‘community’. This community has shared concerns such as a mission, security requirements, policy, and compliance considerations. It may be managed by the organizations or a third party and may exist on premise or off premise.
- Hybrid Cloud. In the case of a hybrid cloud deployment solution, the cloud infrastructure is a composition of 2+ clouds (private, community or public) which remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
