This book constitutes the refereed proceedings of the ACM/IFIP/USENIX
14th International Middleware Conference, held in Beijing, China, in
December 2013. The 24 revised full papers presented were carefully
reviewed and selected from 189 submissions. The papers cover a wide
range of topics including design, implementation, deployment and
evaluation of middleware for next-generation platforms such as cloud
computing, social networks and large-scale storage and distributed
systems. The middleware solutions introduced provide features such as
availability, efficiency, scalability, fault-tolerance, trustworthy
operation and support security and privacy needs.
