摘要：How to improve the utilization of IT facilities is a major problem for enterprises which have many real-time control systems. We think that improving or rebuilding legacy applications using cloud computing ideology is more suitable than building new cloud platform for these traditional real-time companies. In this paper, we propose federate cloud (FC) architecture for large group company having many subsidiaries with the similar real-time applications based on centric model. In the FC architecture, a sub cloud is constructed for applications in each subsidiary and all the sub clouds are connected together by cloud bus. We discuss the detailed mechanism for the FC architecture, including construction of the FC component, the real-time cloud storage strategies and cloud service scheduling algorithm. Experiment results show that our method can improve the utilization of IT facilities effectively. © 2013 IEEE.
