    Process Engine Benchmarking with Betsy in the Context of ISO/IEC Quality Standards
    (Softwaretechnik-Trends Band 36, Heft 3, 2016) Geiger, Matthias; Harrer, Simon; Lenhard, Jörg
    Business process management and automation has been the focus of intense research for a long time. Today, a plethora of process languages for specifying and implementing process models have evolved. Examples for such languages are established international standards, such as BPEL 2.0 or, more recently, BPMN 2.0. Implementations of these standards which are able to execute models, so called process engines, differ in their quality of service, e.g., in performance or usability, but also in the degree to which they actually implement a given standard. Selecting the “best” engine for a particular use case is hard, as none of the existing process standards features an objective certification process to assess the quality of its implementations. To fill this gap, we present the current achievements in process engine benchmarking and point out future directions.

    Towards uniform BPEL engine management in the cloud
    (Informatik 2014, 2014) Harrer, Simon; Lenhard, Jörg; Wirtz, Guido; Lessen, Tammo Van
    The Web Services Business Process Execution language (BPEL) is a standard for modeling and executing automated processes and is tailor-made for service orchestration. BPEL specifies a serialization format which every BPEL implementation has to understand, thus allowing for the portability of processes among runtime engines. Although the modeling and execution of BPEL processes is portable between engines to a large degree, the lifecycle management of BPEL processes is not standardized and varies a lot for different engines. This paper presents a first approach for a uniform and cloud-based lifecycle management of BPEL processes and engines. We infer a uniform interface for the lifecycle management from the capabilities of current engines and provide a prototypic implementation of a tool that manages processes and engines on a TOSCA-compliant infrastructure.
