An example system for bridging between networks includes a first server that launches a first virtual machine in a first network. The system includes a first network controller that is coupled to the first network and sends a request for a bridge between the first network and a second network. The system also includes a second server that launches a second virtual machine in the second network. The system further includes a second network controller that is coupled to the second network, receives the request for the bridge, and in response to the request, creates the bridge between the first and second networks. The bridge enables the first virtual machine in the first network to communicate with the second virtual machine in the second network.
