Title
QoS-aware Service Selection and Cloud-based Resource Allocation for Service Choreographies

Abstract

Service choreographies, and service compositions in general, rely on the proper choice of service implementations, service providers, and resource providers in order to fulfill their requirements. Besides service functionality, this choice must based on non-functional criteria, such as quality of service and efficiency of resource utilization. In this talk, I will cover ongoing research on service selection and dynamic cloud resource allocation as part of an approach for the deployment and enactment of multiple service choreographies. The approach is based on the selection of the most appropriate service to fulfill each choreography role, taking into account the possibility of sharing services among different choreographies. The result of service selection is then used as the basis for QoS-aware resource allocation using multiple cloud providers, including private and public clouds. I will present current results, followed by ongoing research and future developments.

Short Bio:

Fábio M. Costa is an associate professor at the Institute of Informatics at the Federal University of Goiás, Brazil. He received his Ph.D. in Computing from Lancaster University (UK) in 2001, where worked as a member of the Distributed Multimedia Research Group. His research interests are in the area of adaptive distributed systems in general and on reflective middleware in particular, adopting concepts from model-driven engineering, notably models@runtime, in order to make reflection more tractable and predictable. Results of this research have been applied in areas such as cloud computing, smart grid, communication platforms, and ubiquitous computing, with a number of recent journal and conference publications. At UFG, he is a permanent member of the Post-Graduate Program in Computer Science. Fabio is a member of the Association for Computing Machinery (ACM) and of the Brazilian Computer Society. He also serves regularly as program committee member and editorial board member for international conferences and journals.
