There are various options available for the cloud hosting options, which are described as below :

Private Cloud : This type of the cloud hosting allows organizations to build servers, network devices and applications behind organization’s own firewall. Organization will have complete control of the datacenter and need to administrate and manage end to end operations. It is quite expensive compare to other cloud hosting models.

Public Cloud : This type of the cloud hosting allows organizations to use servers, network devices and applications that are hosted publicly.  The cloud service providers example Azure, AWS will manage and administrate the end to end operations. Organizations can rent these computing services. This is not expensive as compare to Private cloud.

Hybrid Cloud: This type of the cloud hosting enables organizations to enjoy the benefits of both public cloud and private cloud. Organizations use private cloud to host sensitive application and use public cloud for the non-sensitive applications. This is bit expensive compare to public cloud but not expensive like private cloud.
