SLA-driven Service Marketplace Monitoring with Grand SLAM

Today, the number of functional equivalent web services increases rapidly. Service search engines and marketplaces are opening up to guide users to their preferred service providers. The question of what is the best service for the user’s demand cannot be answered sufficiently. While semantic matchmaking techniques attempt to solve this question mainly for functional aspects, it is also important to know non-functional properties of a service like its availability and response time as well as the provider’s level of fulfilment of contractual obligations regarding these properties. To realise the automated monitoring of services and contracts on service marketplaces, we introduce a standalone and easily integratable software component which is able to monitor non-functional properties and the adherence to negotiated contracts.
