Abstract. Object caching is a desirable feature to improve the both scalability and performance of distributed application systems for information infrastruc-ture, the information management system leveraging the power of network computing. However, in order to exploit such benefits, we claim that the fol-lowing problems: cache server placement, cache replacement, and cache syn-chronization, should be considered when designing any object cache system. We are under developing DOC: a Distributed Object Caching, as a part of building our information infrastructures. In this paper, we show how each prob-lem is inter-related, and focus to highlight how we handle cache server deploy-ment problem.
