Proceedings of the 20th International Middleware Conference

This edition marks the 13th ACM/IFIP/USENIX Middleware Conference. The first conference was held in the Lake District of England in 1998, and its origins reflected the growing importance of middleware and the realization that middleware represented an active, rigorous, growing and evolving research discipline in its own right. The definition of the term "middleware" has also evolved in the past decade, but retains, at its core, the notion of different levels/layers of abstractions in distributed-computing systems. Since its inception, the Middleware Conference has remained a premier forum for the discussion of innovations and recent advances in the design, implementation, experimentation, deployment, and usage of middleware systems.
