The 4th AOSD Workshop on Aspects, Components, and Patterns for Infrastructure Software (ACP4IS)

Call for papers (pdf)

The importance of "systems infrastructure" software -- including application servers, virtual machines, middleware, compilers, and operating systems -- is increasing as application programmers demand better and higher-level support for software development. Vendors that provide superior support for application development have a competitive advantage. The software industry as a whole benefits as the base level of abstraction increases, thus decreasing the need for application programmers to continually "reinvent the wheel."

These trends, however, mean that the demands on infrastructure software are increasing. More and more features and requirements are being "pushed down" into the infrastructure, and the developers of systems software need better tools and techniques for handling these increased demands. In particular, developers need better techniques for modularizing, combining, and analyzing the many features that are now being demanded from infrastructure software.

This meeting of the ACP4IS workshop will focus on the particular topic of implementing infrastructure software product families. A software product family is a group of systems, designed around a shared set of features and implemented using a common set of parts. Each member of a family is implemented as a unique assembly or configuration of parts; as a result, different family members have different feature sets. Aspects, components, and patterns have all been used to implement software product families. The goal of this year's workshop is to better understand how these techniques relate, individually and in combination, to the inherent challenges of systems infrastructure product families. Critical issues include untangling the inherent complexity of infrastructure software; obtaining strong assurances of correct and predictable behavior; achieving maximum run-time performance; and dealing with the large body of existing systems software components. Suggested topics for position papers include, but are not restricted to:
