Preseving distributed systems' critical properties: A model-driven approach

As information users move increasingly toward distributed systems to supply basic information infrastructure, the ability of such systems to guarantee basic properties over time increases in importance. This article describes a model-based process for efficiently coordinating the use of distributed-computing resources to help identify viable configurations of systems and software for meeting stringent quality-of-service and PSA requirements. This process, called Skoll DCQA, provides an efficient approach to navigating the very large space defined by all possible system and software settings in a modern system.
