A Virtual Private Cloud (VPC) is a method for partitioning a public computing utility such as Amazon EC2 into quarantined virtual infrastructure. A VPC may encapsulate multiple local and remote resources to appear as a single homogeneous computing environment bridging the ability to securely utilize remote resources as part of an seamless global compute infrastructure.
A core component of a VPC is a virtual private network (VPN) and or a virtual LAN (Vlan) in which some of the links between nodes are encrypted and carried by virtual switches. Another reason for the use of a VPN within the context of a VPC includes the ability to virtualize the network giving it particular characteristics & appearance that match the demands as well as requirements of a given application deployed in the cloud.
A VPC enables virtual to cloud (V2C) and physical to cloud (P2C) migrations whereby a operating environment is seamlessly moved from a traditional hosting environment to that of a cloud with little or no interference to the operations of a given server instance and its performance.
