Patent attributes
A peripheral device includes one or more processors and a memory storing program instructions that when executed implement an extension manager of a virtualized computing service. The extension manager establishes a secure network channel for communications between the peripheral device, which is located at a premise external to a provider network, and a data center of the provider network. The extension manager assigns a network address of the substrate network of the service to a hardware server at the external premise. The substrate address is also assigned to an extension traffic intermediary at the data center. In response to a command directed to the virtualized computing service, one or more compute instance configuration operations are performed at the hardware server.
