Service deployment on global-scale network is a time-consuming and complicated work if the work is really done on global-scale — not only limited to a corner of near-by sites. The network condition is varying at every moment, and the only thing that predictable is un-predictability. In this paper, we proposed and implemented a novel tool named ImDeploy for doing global-scale service deployment. It is adaptive to varying network condition by first clustering the target hosts by their network distance and deploying service to cluster leaders, and then deploying service inside clusters. The design and the implementation of ImDeploy also considered the scalability and user interface aspects. Through evaluation, it is proved that ImDeploy is a suitable and easy-to-use tool for global-scale service deployment.
