Embodiments generally provide techniques for mapping service modules on a network device. Embodiments identify a plurality of service modules, each configured to perform a respective service. A first one of the plurality of service modules is mapped to a first one of a plurality of virtual switches on the network device. Service policy information for a plurality of virtual switches is retrieved. The service policy information is indicative of service requirements for each of the plurality of virtual switches. Upon detecting an occurrence of a predefined event, embodiments determine a second one of the plurality of virtual switches to map the first service module to, based on the service policy information. The first service module is then mapped to the second virtual switch.
