A real-time message delivery method of publish/subscribe model in distributed cloud environment

The cloud computing environment is distributed for real-time performance, response time guarantees, and load balancing. The publish/subscribe model is also being studied for distributed cloud environment. This paper proposes a Distributed Message Broker Service(DMBS) that can reduce the network traffic load of centralized server and provide seamless messaging services on distributed cloud environment. DMBS can deploy message brokers on distributed cloud environment and support real-time message transmission service. Our experimental evaluation shows about 10% enhancements of message transmission performance and resource usage in centralized server.
