Software Performance Engineering in the DevOps World

The GI-Dagstuhl seminar on Software Performance Engineering in the DevOps World (seminar number 16394) addresses the problem of performance-aware DevOps. Both, DevOps and performance engineering have been growing trends over the past 1 to 2 years, in no small part due to the rise in importance of identifying performance anomalies in the operations (Ops) of cloud and big data systems and feeding these back to the development (Dev). However, so far, the research community has treated software engineering, performance engineering, and cloud computing mostly as individual research areas. The goal of this seminar is to bring together young researchers from all of those fields, to identify cross-community collaboration, and to set the path for long-lasting collaborations towards performance-aware DevOps.

Date and Location

September 26th – September 30th 2016, Schloss Dagstuhl, Germany. This seminar is by invitation only.


The main goal of the GI seminar is to bring together young researchers (PhD students in a later stage of their PhD, as well as PostDocs or Junior Professors) in the areas of (i) software engineering, (ii) performance engineering, and (iii) cloud computing and big data to present their current research projects, to exchange experience and expertise, to discuss research challenges, and to develop ideas for future collaborations:

  • The seminar will provide a joint forum for participants coming from different research.
  • The participants will learn about the newest developments in their own as well as adjacent research areas.
  • The seminar will foster interaction among the participants and establish collaborations between the researchers towards joint research projects.

Andre van Hoorn is the interim professor for Reliable Software Systems (RSS) at the University of Stuttgart (Institute of Software Technology), Germany. He holds a PhD degree from Kiel University, Germany and a Master’s degree (Dipl.-Inform.) from the University of Oldenburg, Germany. His research interests include combining model-based and measurement- based performance evaluation techniques, and he is known for his work on and around the Kieker monitoring framework. Andre is member of ACM and GI, actively contributing to the Standard Performance Evaluation Corporation (vice-chair and steering committee member of the SPEC Research Group (RG), and co-founder and chair of the SPEC RG DevOps Performance Working Group).

 Pooyan Jamshidi is a post-doctoral research associate in the Department of Computing at Imperial College London. Pooyan holds a PhD in Computing from Dublin City University, Ireland. His research interests lies predominantly in the areas of self-adaptive software, where he applies machine learning techniques to enable self-adaptation in distributed systems mainly in cloud computing and for big data applications. Pooyan is currently involved in two EU projects, FP7 MODAClouds and H2020 DICE, where in both projects his research involved developing tools and services to enable DevOps for multi-cloud and big data applications. He has 8 years of experience in software industry.

Philipp Leitner is a senior research associate at University of Zurich, where he leads a team working on the intersection of distributed systems and software engineering. This includes research on topics such as studying how cloud software is being implemented or proposing frameworks to ease the implementation or evaluation of cloud platforms. A particular research focus of Philipp currently is how to make software developers more aware of the runtime implications of their development decisions (e.g., warning them in advance before they commit functionally correct but badly performing code). Right now, he is probably most known for his work on quality prediction and optimisation for service-based systems, and for the QoS-aware service registry VRESCO.

Ingo Weber is a Senior Researcher and Team Leader in the Software Systems research group at Data61 | CSIRO in Sydney, Australia, as well as an Adjunct Senior Lecturer at the University of New South Wales (UNSW). He has published around 70 refereed papers and two books, including “DevOps: A Software Architect’s Perspective”. His research interests include DevOps, cloud computing, business process management, and dependability. Prior to Data61 | CSIRO (formerly: NICTA), Ingo worked at UNSW and at SAP Research in Karlsruhe, Germany. While at SAP, he completed his PhD thesis with the University of Karlsruhe (TH).
