Abstract
With the significant increase in Topology and Orchestration Specification for cloud applications (TOSCA) orchestration services on the Network Functions Virtualization (NFV) cloud platforms. We apply the TOSCA metadata model to orchestrate NFV virtual applications and implement the orchestration system based on the Network Function Virtualization (NFV) Management And Orchestration (MANO) architecture to deploy these virtual applications to the virtual network function (VNF) as the part of cloud services. The proposed orchestration system uses TOSCA service templates to orchestrate virtual applications without complex schemes. And in the end we evaluate the performance for orchestrating and automating cloud services in our cloud environment.
