The cloud is ''public'' only in the sense that, potentially, any person or organisation that requires the provided services can become a consumer, and a public cloud may not necessarily be of universal interest. For example, a SaaS public cloud might provide an accounting system that is useful only to certain types of small business.

'''Private clouds''' are cloud systems that are accessible only by a single 
entityconsumer, or by an exclusive group of related entities that share the same purpose and requirements, such as all the business units in a single organisation. They are generally single-tenanted, but they can be multi-tenanted if the individual group members act as separate consumers. They may be owned by a cloud provider and be located off-premise, or they may be owned and operated by the consumer and be located on-premise. In the latter case, they can also be known as '''internal clouds''' or '''corporate clouds'''.<ref name=PrivateInternal>{{cite web|url= http://searchcloudcomputing.techtarget.com/definition/private-cloud/|title= Private cloud (internal cloud or corporate cloud) |publisher= TechTarget |date= |accessdate=28 February 2012}}</ref>
