1. A method, comprising:

  • identifying a first hardware unit of a plurality of hardware units associated with a network function virtualization (NFV) based communication network, the first hardware unit being identified based on a first load characteristic associated with the first hardware unit;

    identifying a first virtual network function (VNF) instance associated with the first hardware unit, the first VNF instance being associated with usage of at least one service;

    identifying at least one traffic route associated with the first VNF instance, the at least one traffic route being associated with usage of the at least one service;

    identifying a second hardware unit for handling at least a portion of a workload associated with the at least one service, the second hardware unit being identified based on a second load characteristic associated with the second hardware unit, and the second hardware unit being capable of utilizing the at least one traffic route;

    initiating a second VNF instance in the second hardware unit; and

    migrating at least a part of the at least one service from the first VNF instance to the second VNF instance without disrupting the service.
