Private Clouds differ from public clouds because individual organizations host their own computer services rather than a third-party cloud service provider like AWS or Azure. This ensures that the resources for one organization are completely isolated from others. Resources may include a private network, software, and hardware dedicated to a specific organization.
While a single organization hosts its own private cloud, the physical hardware can be housed by that organization or by a third-party provider. Private clouds are beneficial because they offer more security, flexibility, control, and scalability than public clouds. A Private Cloud may also be hosted as part of a Public Cloud infrastructure, and such a Virtual Private Cloud (VPC) offers Public Cloud benefits while meeting Private Cloud security and privacy requirements.
