As IT systems are becoming more and more important, one of the main concerns is that users may face major breakdowns and eventually incur major costs if computing systems do not meet the expected performance requirements: customers expect reliability and performance guarantees, while under-performing systems lose revenues. For example, it has been reported that Amazon tried delaying the page generation by 100 ms and found out that even very small delays would result in substantial and costly drops in revenue (1% sales drop for 100 ms delay). In this talk I will discuss some performance models aiming at optimizing the revenue earned by IT providers running jobs subject to Quality of Service (QoS) constraints and present a middleware architecture for Web Service provision. Experimental results show that revenues can be dramatically improved by imposing suitable conditions for accepting incoming traffic.

Short Bio:
Michele Mazzucco earned his BSc and MSc at the University of Bologna (Italy) in 2003 and 2005, and received his PhD from Newcastle University (UK) in 2009 (advisor Prof. Isi Mitrani) with a thesis on optimization problems in the context of commercial data centers. From 2006 to 2008 he worked as a Research Associate at N'cle, funded by British Telecom (BT). He is currently a Marie Curie Fellow at the University of Cyprus.
