PRIVATE CLOUD
Private cloud is defined as computing services offered either over the internet or a private internal network and only to select users. 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-premise.
A private cloud is a single-tenant environment, meaning the organization using it (the tenant) does not share resources with other users. Those resources can be hosted and managed in a variety of ways.
Private cloud is the second of cloud models which can be public, private, hybrid, multicloud or any combination of the three. All models share common basic elements of cloud infrastructure such as requiring an operating system, however various types of software, such as virtualization, stacked on top of the operating system is what determines how the cloud will function and distinguishes the models.
The main advantage of a private cloud is that users do not share resources. Because of its proprietary nature, a private cloud computing model is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements. In addition to these benefits private clouds are also preferred for:
- Increased security of an isolated network.
- Increased performance due to resources being solely dedicated to one organization.
- Increased capability for customization.
