Private cloud refers to a model of cloud computing where IT services are provisioned over private IT infrastructure for the dedicated use of a single organization.
Private clouds may also be referred to as enterprise clouds or internal cloud or corporate cloud.
When an organization properly architects and implements a private cloud, it can provide most of the same benefits found in public clouds, such as user self-service and scalability, as well as the ability to provision and configure virtual machines (VMs) and change or optimize computing resources on demand. An organization can also implement chargeback tools to track computing usage and ensure business units pay only for the resources or services they use.
Private clouds are often deployed when public clouds are deemed inappropriate or inadequate for the needs of a business. For example, a public cloud might not provide the level of service availability or uptime that an organization needs. In other cases, the risk of hosting a mission-critical workload in the public cloud might exceed an organization’s risk tolerance, or there might be security or regulatory concerns related to the use of a multi-tenant environment. In these cases, an enterprise might opt to invest in a private cloud to realize the benefits of cloud computing, while maintaining total control and ownership of its environment.
The Benefits Of The Public Cloud Include:
Ideal for mission-critical business applications
Data centre consolidation
Scalability and elasticity
Increased security (the private cloud operates behind a company’s firewall and internal hosting)
