Private clouds are those that are built exclusively for an individual enterprise. They allow the firm to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment. There are two variations of private clouds:
On-Premise Private Cloud: This format, also known as an “internal cloud,” is hosted within an organization’s own data center. It provides a more standardized process and protection, but is often limited in size and scalability. Also, a firm’s IT department would incur the capital and operational costs for the physical resources with this model. On-premise private clouds are best used for applications that require complete control and configurability of the infrastructure and security.
Externally-Hosted Private Cloud: This private cloud model is hosted by an external cloud computing provider (such as Eze Castle Integration). The service provider facilitates an exclusive cloud environment with full guarantee of privacy. This format is recommended for organizations that prefer not to use a public cloud infrastructure due to the risks associated with the sharing of physical resources.
