With this talk, he mainly want to introduce himself and get to know us 🙂
A more official version could be:
Networked and distributed systems are becoming more and more virtualized and software-defined. This introduces great opportunities and flexibilities, e.g., in terms of efficient resource sharing, but also
new challenges, e.g., in terms of predictable performance. In this talk, I will present some of our recent work in this area. For example, I report on Kraken (IEEE INFOCOM 2016), a system which provides predictable and elastic performance for Hadoop applications running in shared environments, through explicit resource reservations. I will also present the main ideas behind C3 (USENIX NSDI 2015) which exploits replica selection flexibilities to reduce tail latency in distributed cloud data stores. Finally, I will elaborate on fundamental challenges of more adaptive and dynamic distributed systems, especially regarding consistent reconfigurations and also security (SIGCOMM HotNets 2015, ACM PODC 2015 and ACM SIGMETRICS 2016).

Speaker: Stefan Schmid
Stefan Schmid studied Computer Science at ETH Zurich (minor: micro/macro economics, internship: CERN) and did his PhD in the Distributed Computing Group led by Prof. Roger Wattenhofer, also at ETH Zurich. As a postdoc, he was fortunate to work with Prof. Christian Scheideler at the Chair for Efficient Algorithms at the Technical University of Munich and at the Chair for Theory of Distributed Systems at the University of Paderborn. From 2009 to 2015, he was a senior research scientist at the Telekom Innovation Laboratories (T-Labs) and at TU Berlin (Internet Network Architectures group headed by Prof. Anja Feldmann). In 2013/14, he was an INP Visiting Professor at CNRS (LAAS), Toulouse, France, and in 2014, he was a Visiting Professor at Université catholique de Louvain (UCL), Louvain-la-Neuve, Belgium. Since the end of 2015, he is an Associate Professor in the Distributed and Embedded Systems group at Aalborg University, Denmark., where he is looking for new friends 🙂
