德国University of Bamberg Guido Wirtz教授学术报告会

Short Bio of Prof. Guido Wirtz Guido Wirtz received after his diploma in computer science (1985) a doctoral degree from the University of Bonn (1990) and a habilitation degree from the University of Siegen (1995). He worked 6 years as an associate professor at the University of Münster. Since 2002, Guido is a full professor for Practical CS and founder of the Distributed Systems Group at the University of Bamberg, Germany. From 2007 through 2009 he acted as dean of the Faculty of Information Systems and Applied Computer Sciences. Guido is a member of the Chief Information Office of his university and since 2011 also the chairman of the board of Bavarian University CIOs. From 10/2011 through 09/2012 he was the Vice President Research and since 10/2012 he is the Vice President Technology/Innovation of the University of Bamberg. His research interests are centered on issues regarding the software development for complex, esp. distributed, systems on all levels. This includes design methods, visual languages and tools for distributed systems development as well as middleware, SOA and cloud computing. His current interests are on the seamless transition from business processes to their implementation in a SOA and cloud context as well as in the correctness, conformance, compatibility and portability issues of process languages like BPMN, BPEL or Windows WF. Guido is the author or co-author of more than 120 publications in international refereed journals and conferences. He is a long-time member of the German computer society GI, the IEEE-CS and the ACM.

Service-Oriented Architecture, Service Ecosystems and Clouds – A Brave New High-Level World for Implementing Interoperable Business Processes?

 

Dr. Guido Wirtz, Distributed Systems Group, Bamberg University, Germany

 

For more than 10 years, SOA and its extensions claim to provide the holy grail for both, enterprise application integration (EAI) as well as business to business integration (B2Bi). More recently, Clouds are predicted to be the next step that makes enterprise IT more flexible and scalable and is best utilized in the context of SOA-based IT strategies. One of the main benefits of the service-oriented architectural style is its focus on service descriptions, interfaces and loose coupling. For the first time, this has made thinking in terms of high-level process specification languages for service composition a real practical choice when implementing modern EAI or B2Bi systems. Most important, this ‘new’ thinking in terms of processes also on the implementation level helps to bridge the fundamental gap between business processes and their detailed implementation in the depths of enterprise IT systems. The rise of standards and their implementation for business process notations, orchestration and choreography languages as well as techniques like model-driven transformation bear the potential to overcome at least some obstacles caused by different levels of abstraction, poor conformance or missing interoperability.

This talk sketches some of the potentials of modern system development based on SOA principles and utilization of process languages, but also discusses the state-of-the-art in real-life systems supporting these principles.  As the main overall criterion, one of the priority statements of the ‘SOA Manifesto’ (www.soa-manifesto.org/default_chinese.html) – “Intrinsic interoperability over custom integration” – is used. The talk reports on results gathered over the last years in our distributed systems group which puts its current focus on this question, in detail:

  • interoperability between Web Service stacks,
  • conformance of  open-source and proprietary BPEL engines w.r.t. the BPEL 2.0 standard,
  • portability of executable BPEL processes based on standard compliance and support level on well-known BPEL engines,
  • expressiveness of process languages like BPEL or Windows Workflow Foundation (WF) measured via pattern-based analysis, as well as
  • interoperability and standard compliance of BPMN 2.0 models and model serializations.

More recently, similar questions, e.g.,  of vendor lock-in when going into ‘the cloud’, are investigated. Without revealing too much, SOA and process-oriented thinking may lead to a new world, but at the moment it is far from ‘brave’.
