Construction method and device of service delivery system

The invention relates to a construction method of a service delivery system. The method includes the following steps that: a service demand instruction is received, wherein the demand instruction carries the type information and basic configuration information of services; a service system virtual machine corresponding to the type information of the services is constructed according to the demandinstruction; and a service delivery virtualization system is constructed according to the service system virtual machine configured and constructed by the basic configuration information and the virtual network of the service system virtual machine. With the construction method adopted, the complete virtualization of application delivery can be realized; and deployment is simpler and more flexible, and the virtualized service delivery network system can be easier to manage and maintain in a unified manner. The present invention further relates to a construction device of a service delivery system corresponding to the
