An Overlapping Architecture for ROIA in Cloud

Real-time online interactive application (ROIA) is an emerging large scale distributed application in recent years. To satisfy the high demands on performance, ROIA needs a highly robust and efficient architecture to cope with the huge concurrent users. Previous works are almost based on the C/S and P2P mode, and these architectures cannot be simply copied to cloud computing environment. In this paper, we propose an overlapping architecture for ROIA in cloud, which based on zoning technique. This new architecture provides redundancy to ensure the robust and enhance the scalability of ROIA. We focus on analyze the two merits of new architecture: seamless migration across zones and protecting against server crash. This paper sheds a little light to the related further research on ROIA.
