One embodiment of the invention features a system including a first gateway and a second gateway that operate in concert to support a migration of a software component from an on-premises network to a public cloud network while preserving an Internet Protocol (IP) address assigned to the software component. The first gateway deployed as part of the on-premises network, and the second gateway deployed as part of the public cloud network. The first and second gateways are in communication via a secure communication path. To support migration of the software component to the public cloud network while retaining its IP address, the second gateway is configured to resolve a media access control (MAC) address for an on-premises host connected to the on-premises network. Similarly, the first gateway is configured to resolve a MAC address for a cloud host connected to the public cloud network.
