Middleware for Dependable Service-Oriented Systems
University of Lugano
Today, creating service-oriented applications is a tedious, manual task. The software designer has to search for relevant services, study their APIs, and integrate them into the desired system, taking also non-functional aspects, such as service costs or reliability, into account. Moreover, current service-oriented systems cannot automatically recover from unforeseen service failures and support neither automated update nor self-tuning of a running system.
In this talk I present a new service-oriented architecture, including a service-composition component that automates the process of creating service-oriented application, as well as a service execution middleware which supports fine-grained monitoring of service execution and enables the automatic replacement of failed or badly performing services. For automated service composition, we have integrated AI planning algorithms with matchmaking in large-scale service directories that advertise available services. Concerning service execution monitoring, we leverage advanced program instrumentation and profiling techniques.
