Orchestration of virtualization technology and application implementation
A virtual network function application is to be deployed in a multi-technology virtualization environment. The multi-technology virtualization environment comprises a plurality of virtualization technologies. The application exists in a plurality of application implementations. At least one of the virtualization technologies has a preferred one of the application implementations. The deployment comprises receiving a trigger for a deployment of the virtual network function application. In response to the trigger, information is obtained about at least one optimization objective and about resource utilization in the multi-technology virtualization environment. Based on the received information, one of the plurality of virtualization technologies is selected for said deployment. One of the application implementations is also selected, and the selected application implementation need not be the preferred application implementation for the selected virtualization technology. The selected application implementation of the virtual network function application is then deployed on the selected one of the virtualization technologies.
