8. The method for network resource management of claim 7 , wherein, in response to the life cycle management service comprising a VNF elastic scaling service and a containerized VNF being deployed on a virtual machine, the virtual machine is elastically scaled first, followed by a container.

9. The method for network resource management of claim 1 , after the performing recourse allocation by the VIM, further comprising:

configuring, by the VNFM, parameters of the life cycle management service for the VNF.

10. The method for network resource management of claim 9 , after the configuring, by the VNFM, parameters of the life cycle management service for the VNF, further comprising:

notifying the NFVO and an EMS the completion of the life cycle management service.

11. A network device, comprising a processor, a memory and a communication bus, wherein:

the communication bus is configured to realize communication between the processor and the memory; and

the processor is configured to execute one or more computer programs stored in the memory to carry out a method for network resource management, comprising:
