VPN: Short for virtual private network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. (Source: Webopedia)

Once one of many, it has become a near standard for all types of computer communication. It is used pervasively, transmitting data to and from a multitude of devices ranging from those in our pockets to spacecraft circling distant planets. Arguably IP is the most successful open standard ever, but as network communications converge under a single standard used for an increasing ... read more

It should come as no surprise that it is possible to have a private cloud within a public cloud infrastructure, in much the same way as we have virtual private networks (VPNs) over the public Internet. The most common unschooled view of the cloud is unfortunately one of confusion, with the belief that it is an amorphous collection of compute resources at an indistinct group of third party sites. That definition more closely resembles the Internet itself, however. Before addressing pub ... read more
