• Private cloud – Cloud infrastructure operated exclusively for an organization. Can be managed by the organization or a third party. The infrastructure can be located on premises or off premises. When operated off premises and hosted by a cloud service provider, this is also sometimes referred to as a dedicated private cloud.

• Public cloud – Cloud infrastructure made available to the public or to a large industry group and owned by an organization that sells cloud services. In the majority of the cases, this environment is partly or completely shared between different customers.

• Hybrid cloud – Cloud infrastructure is a composite of two or more cloud instances (private and public) that are unique entities but are also bound together by standardized technology. This is primarily the tenant/customer view as they mix public and private cloud resources.
