Step 4: Assess Potential Cloud Delivery Models
There are currently four possible cloud delivery models from which solution providers can choose, Sobel said:
* Private clouds, where access to the cloud infrastructure is limited to a single tenant and both hosted and local resources are dedicated to that tenant.
* Public clouds, which are multi-tenant cloud infrastructures managed by a third party and open to anyone to use.
* Community clouds, in which a group of companies with similar requirements share a private cloud.
* Hybrid clouds, which link public and private clouds. For example, Sobel said, a company might run Office 365 in a public cloud in conjunction with Microsoft Active Directory in a private cloud.
