A private cloud aims at providing public cloud functionality, but on private resources, while maintaining control over an organization’s data and resources to meet security and governance’s requirements in an organization. Private cloud exhibits a highly virtualized cloud data center located inside your organization’s firewall. It may also be a private space dedicated for your company within a cloud vendor’s data center designed to handle the organization’s workloads.

Private clouds exhibit the following characteristics:
» Allow service provisioning and compute capability for an organization’s users in a self-service manner.
» Automate and provide well-managed virtualized environments.
» Optimize computing resources, and servers’ utilization.
» Support specific workloads.

There are many examples for vendors and frameworks that provide infrastructure as a service in private setups. The best-known examples are Eucalyptus and.

It is also important to highlight a third type of cloud setup named “hybrid cloud,” in which a combination of private/internal and external cloud resources exist together by enabling outsourcing of noncritical services and functions in public cloud and keeping the critical ones internal. Hybrid cloud’s main function is to release resources from a public cloud and to handle sudden demand usage, which is called “cloud bursting.”
