private cloud storage
A form of cloud storage where the enterprise data and cloud storage resources both reside within the enterprise's data center and behind the firewall. Also known as internal storage clouds, private cloud storage services are managed inside the data center and as a result almost always carry higher capital and maintenance costs than public cloud storage services due to the enterprise needing to provide the data center space, network connectivity, power and cooling.
Private cloud storage does help resolve the potential for security and performance concerns while still offering many of the benefits of cloud storage such as scalability, reliability, rapid deployment and the option of management by a specialized cloud storage provider.
