虚拟私有云 （Virtual Private Cloud, VPC） 是存在于共享或公用云中的私有云 （Private Cloud），亦即一种网际云（Intercloud）。

Amazon Web Services 在 2009-08-26 发表了 Amazon Virtual Private Cloud，该服务允许用户透过 IPsec 虚拟私有网络 (VPN) 来链接 Amazon Elastic Compute Cloud (EC2)。

Google App Engine 在 2009-04-07 发表的 Secure Data Connector 产品中也支持类似的功能。

A Virtual Private Cloud (VPC) is an on-demand configurable pool of shared computing resources allocated within a public cloud environment, providing a certain level of isolation between the different organizations (denoted as users hereafter) using the resources. The isolation between one VPC user and all other users of the same cloud (other VPC users as well as other public cloud users) is achieved normally through allocation of a Private IP Subnet and a virtual communication construct (such as a VLAN or a set of encrypted communication channels) per user. In a VPC solution, the previously described mechanism, providing isolation within the cloud, is accompanied with a VPN function (again, allocated per VPC user) that secures, by means of authentication and encryption, the remote access of the organization to its VPC cloud resources. With the introduction of the described isolation levels, an organization using this service is in effect working on a 'virtually private' cloud (that is, as if the cloud infrastructure is not shared with other users), and hence the name VPC.
