Performance Modelling of large-scale DTP Systems
Distributed Transaction Processing Systems are nowadays used in most service industries to handle their productive day-to-day business. During load peaks, these enterprise systems often experience high latencies and response times develop in a non-linear way. In this project we develop new models to analyze and optimize throughput based on business priorities and manage the system capacity of large-scale DTP systems. founded by Bayerische Forschungsstiftung, in cooperation with Telefónica o2 Germany and iterate |
Theseus / Texo - Performance Analysis of Service Orchestrations THESEUS is a research program initiated by the German Federal Ministry of Economy and Technology (BMWi), with the goal of developing a new Internet-based infrastructure in order to better use and utilize the knowledge available on the Internet. The aim of the TEXO application scenario within THESEUS is to provide businesses with an infrastructure for new web-based applications and services, on the basis of service oriented architecture (SOA). In this project we address the task of predicting performance measures like end-to-end workflow response times, throughput, or service component utilizations in orchestrated business processes.

Policy-based Admission Control IT service providers are increasingly hosting different services on shared infrastructures. While this fosters system utilization, system failovers, unexpected service behaviour or peak demands for one or more services may exploit resource pools entailing performance losses and service level violations. The aim of this research project is the development of new models and methods for dynamic admission control on shared infrastructures to prevent overload situations and to provide services according to agreed service levels.
