Provided is a method and a network apparatus in a cloud infrastructure. The network apparatus includes a processor, and a memory coupled to the processor, the memory for storing computer instructions that, when executed by the processor, cause the processor to generate a resource abstraction layer relating a network cluster including a first server architecture with a first resource set and a second server architecture with a second resource set, to generate an orchestration layer configured to receive a packet flow request and, in response to the packet flow request, schedule virtual network resources based on the resource abstraction layer for servicing a packet flow, and to deploy the virtual network resources to receive and service the packet flow.
