Emerging Internet-based services: new frontiers for performance models and applications

The integration of the computer and telecommunication products of the academy and industry is giving impressive impulses to systems, languages, applications, services. The performance community caught this train only in part. There has been an increment of monitoring and workload characterization activities, but the real core represented by modeling and resolution activities seems to be confined to the lower layers of the system and network infrastructure. Few braves touched the top layers of the applications that represent the main interest for the real world. The main focus will not be on the performance models for the design stage, but on the phases following the realization of these systems and services. This includes the tuning-testing, the operational, and the post-production stage including capacity planning. The good news is that there is a huge potential for involving performance models and modelers in each of these phases.
