Abstract:
1. A computer-implemented method comprising: receiving configuration information indicating a specified network topology for a first virtual computer network and indicating multiple virtual network addresses for use with multiple computing nodes of the first virtual computer network, wherein the multiple virtual network addresses include an indicated range of virtual network addresses that are a subset of the multiple virtual network addresses and that are for use with an external location having a first external device of the first virtual computer network, wherein the multiple computing nodes are connected to a substrate network, and wherein the external location of the first external device is separated from the substrate network via one or more external connections that are not part of the substrate network; and providing, by one or more programmed computing systems, the first virtual computer network in accordance with the received configuration information by overlaying the first virtual computer network on the substrate network without physically implementing the specified network topology for the first virtual computer network, the providing of the first virtual computer network including:
