Dynamic set-up of Monitoring Infrastructures for SLA Management

Monday, January 18th, 2010

Over the last few years, several approaches have been developed to support the monitoring of SLAs. Typically, these approaches collect events during service executions and use them to check whether the properties of service provision as specified in an SLA are satisfied. Such approaches provide state of the art mechanisms for performing the basic checks [...]

Challenges in SLA Translation

Tuesday, December 1st, 2009

Service-Oriented Architecture (SOA) represents an architectural shift for building business applications based on loosely coupled services. In a multi-layered SOA environment the exact conditions under which services are to be delivered can be formally specified by Service Level Agreements (SLAs). However, typical SLAs are just specified at the top-level and do not allow service providers [...]

Financial applications are particularly suited to grid-based experimentation and research. A Financial Live Trading System is used an exemplar in this article. The emerging growth of worldwide trading and the reliance on automated processing has increased the complexity and volatility [...]

Complex Service Management

Wednesday, August 12th, 2009

Originally, (Web) services were deployed and used with almost no actual control by the different parties. The simplistic assumption that their behavior was correct and everyone had to be happy with the functionality provided was unrealistic. The actual exploitation of services, imposed us to start conceiving different methods and tools to manage the complete life-cycle of deployed and running services with special emphasis on the actual run-time behavior.
