A method is executed by a computing device to receive a request for a server via a known network access type, from a known application type, by a known user, or a known policy, instantiate a new unikernel with a differentiated communication protocol stack instance, in response to determining the request is not being serviced by a previously instantiated unikernel, and service the request by a previously instantiated unikernel, in response to determining the previously instantiated unikernel is available, where the new unikernel and the previously instantiated unikernel are separate from an operating system of the computing device.
