Private Cloud
(Context: Technology Management)
1. The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off- premises. Private cloud options include:
- Self-hosted Private Cloud - a Self-hosted Private Cloud provides the benefit of architectural and operational control, utilizes the existing investment in people and equipment, and provides a dedicated on-premises environment that is internally designed, hosted, and managed.
- Hosted Private Cloud - a Hosted Private Cloud is a dedicated environment that is internally designed, externally hosted, and externally managed. It blends the benefits of controlling the service and architectural design with the benefits of data center outsourcing.
- Private Cloud Appliance - a Private Cloud Appliance is a dedicated environment procured from a supplier that is designed by that supplier with provider/market driven features and architectural control, is internally hosted, and externally or internally managed. It blends the benefits of using predefined functional architecture and lower deployment risk with the benefits of internal security and control.
2. Private Cloud is defined as computing services offered either over the Internet or a private internal network and only to select users instead of the general public. Also called an internal or corporate cloud, private cloud computing gives businesses many of the benefits of a public cloud - including self-service, scalability, and elasticity - with the additional control and customization available from dedicated resources over a computing infrastructure hosted on-premises.
