Abstract: Techniques are described to provide service or network function workload preemption. In one example, a method includes identifying a network location at which a first function can be instantiated; determining whether compute resources are available at the network location to instantiate the first function; based on determining that compute resources are available, instantiating the first function; based on determining that compute resources are not available, determining whether preemption of a second function can be performed at the network location, wherein determining whether preemption of the second function can be performed is based, at least in part, on a comparison between a setup priority of the first function and a holdover priority of the second function; and, based on determining that preemption of the second function at the network location can be performed, performing preemption of the second function and instantiating the first function at the network location.
