The annual ACM/IFIP/USENIX Middleware conference is a major forum for the discussion of innovations and recent advances in the design, implementation, experimentation, deployment, and usage of middleware systems. Middleware is the software that resides between applications and the underlying architecture and platforms, often with an emphasis on networked computing. The goal of middleware is to facilitate the development of applications by providing higher-level abstractions for better programmability, performance, scalability, security, and a variety of essential features. It is a rapidly evolving and growing field. Following the success of past conferences in this series, the 14th International Middleware Conference will be the premier event for middleware research, technology and experimentation in 2013. The scope of the conference is the design, implementation, deployment, and evaluation of system platforms and architectures for current and future computing, storage, and communication environments. Highlights of the conference will include a high quality technical program, invited speakers, an industrial track, panel discussions involving academic and industry leaders, poster and demonstration presentations, a doctoral symposium, and workshops.
