1st International Workshop on Performance and Conformance of Workflow Engines
The goal of the 1st International Workshop on Performance and Conformance of Workflow Engines (PEaCE) is to bring the research and industrial practice together, towards topics that are related to the conformance and performance of workflow management systems. The workshop is co-located with the 5th European Conference on Service-Oriented and Cloud Computing (ESOCC 2016) and takes place on September 5th, 2016, in Vienna, Austria.
Workflow management systems provide platforms for delivering complex service-oriented applications that need to satisfy enterprise-grade quality of service requirements such as dependability and scalability. Benchmarking is an established practice that helps to drive continuous improvement of technology by setting a clear standard and measuring and assessing its performance. For example, transaction processing benchmarks have been introduced since a long time and over decades they have been instrumental to achieve an enormous performance improvement of database technology, e.g., with the TPC family of benchmarks. Conversely, benchmarks for service oriented computing in general and workflow management systems in particular have started to appear only recently and there is no currently accepted standard benchmark.
Any vendor can claim that their product is standard compliant while still implementing different subsets or interpretations of the standard, since there is no certification authority for both of the most popular and widespread business process languages standards BPEL and BPMN. The different interpretations and implementations of the standards led and still lead to vendor lock-ins as porting a standard compliant workflow involves too much effort, and sometimes is not possible at all - effectively killing the standard inherent argument for portability. Benchmarks for standard conformance have not been around for long in the area of WfMSs, and still lack scientific foundation in their creation and execution.
This workshop aims to bring researchers and industry together in the topics benchmarking and standard conformance in the area of workflow management systems. Workflows is an established way of implementing service composition. The benefit for the community will be to learn about the state of the art in services composition using workflows, both from the research and the industry perspective.
- Benchmarking performance of workflow management systems
- Measuring conformance of workflow management systems
- Benchmarking and measuring workflow management systems in the cloud
- Benchmark design (workload models of workflows, methods deriving conformance test suites)
- Benchmark usages (workflow management systems comparison and selection)
Format of the Workshop
Cooperation among industry and academia is an important target for the workshop. Thus, the workshop will feature contributions from different stakeholders and consist of three parts:
- Scientific talks
- Industry talks
- A panel discussion
