Abstract: Techniques disclosed herein permit logical topologies of datacenters to be automatically learned and re-created in the cloud. In one embodiment, a datacenter landscape is determined based on numbers of hops from nodes in a datacenter to a wide area network (WAN)-facing node. Such a datacenter landscape may then be re-created in the cloud. In another embodiment, virtual appliances are deployed using templates with user-tunable parameters. What would have been set up manually in a physical datacenter, such as connecting a new router to other devices, is then simplified to adjusting parameters of the template to specify, e.g., that the router is a routed hop rather than a bump in the wire, with the router then being automatically deployed in the specified manner.
