Private cloud is particularly assigned to a company using VPN. The VPN is called virtual private network. This post tells you not only features but also benefits. What is virtual private cloud: The concept of a virtual private cloud (VPC) has emerged recently. In a typical approach, a VPC connects an organization's information technology (IT) resources to a dynamically allocated subset of a cloud provider's resources via a virtual private network (VPN). Organizational IT controls are then applied to the collective resources to meet required service levels. As a result, in addition to improved TCO, the model promises organisations direct control of security, reliability and other attributes they have been accustomed to with conventional, internal data centres. The VPC concept is both fundamental and transformation. First, it proposes a distinct abstraction of public resources combined with internal resources that provides equivalent functionality and assurance to a phy...
