Architecture design for management as a service cloud

This paper presents a novel Management-as-a-Service (MaaS) architecture which is based on cloud computing architecture and provides more scalable network management capabilities to network managers. Ontology based semantic information model which supports communications between management services described by heterogeneous information, and functional model which schedules the deployment of each management service are designed to support the cloud network management architecture by providing appropriate management information description and service deployment method. We realize a prototype of cloud network management architecture based on the MaaS model, evaluate the performance of cloud network management services and validate the functional model used in the MaaS cloud. Experiment results show that our functional model provides optimal deployment of each cloud service and the elasticity of cloud management services improve both the management efficiencies and the utilization of management resources.
