  /**
   * <p>Tacker - OpenStack NFV Orchestration</p>
   *
   * <p>Tacker is an official OpenStack project building a Generic VNF Manager (VNFM) and a NFV Orchestrator (NFVO) to deploy and operate
   * Network Services and Virtual Network Functions (VNFs) on an NFV infrastructure platform like OpenStack.
   * It is based on ETSI MANO Architectural Framework and provides a functional stack to Orchestrate Network Services end-to-end using VNFs.</p>
   *
   * <p>Vnf Stands for Virtual Network Functions. This is the VNF Management API Service which is used to Deploy VNFs..</p>
   *
   * <p>
   * <u>VNFM</u>:
   * <ul>
   * 		<li>Basic life-cycle of VNF (create/update/delete).</li>
   * 		<li>Enhanced platform-aware (EPA) placement of high-performance NFV workloads.</li>
   * 		<li>Health monitoring of deployed VNFs.</li>
   * 		<li>Auto Healing / Auto Scaling VNFs based on Policy.</li>
   * 		<li>Facilitate initial configuration of VNF.</li>
   * </ul>
   * </p>
