To effectively share computation resources over the wide area network among a variety of data intensive applications, a scalable computation service needs to be provisioned. The end-to-end principles provide a scalable approach to the architecture of shared services on which these applications depend. We have shown the use of a best-effort network storage service, the Internet Backplane Protocol (IBP), for scalable data sharing by applying the end-to-end principles. This paper explores a way to scalable network computation by adhering to the end-to-end principles and discusses the costs to achieve scalability in our design
