IT resources are provided as a service exclusively to one customer in order to meet high requirements on privacy, security, and trust while enabling elastic use of a static resource pool as good as possible.
|How can the cloud properties – on demand self-service, broad network access, pay-per-use, resource pooling, and rapid elasticity – be provided in environments with high privacy, security and trust requirements?|
Many factors, such as legal limitations, trust, and security regulations, motivate dedicated, company-internal hosting environments only accessible by employees and applications of a single company.
Cloud computing properties are enabled in a company-internal data center. Alternatively, the Private Cloud may be hosted exclusively in the data center of an external provider, then referred to as outsourced Private Cloud. Sometimes, Public Cloud providers also offer means to create an isolated portion of their cloud made accessible to only one customer: a virtual Private Cloud.
