    Analyzing and Improving the Performance of Continuous Container Creation and Deployment
    (Softwaretechnik-Trends Band 43, Heft 4, 2023) Alamoush, Ahmad; Eichelberger, Holger
    Continuous Deployment automates the delivery of new versions of software systems. To ease installation and delivery, often container virtualization is applied. In this paper, we discuss the impact of different (Docker) container image creation techniques for variant-rich Industry 4.0 applications. Our results show that a combination of techniques like container image stacking or semantic fingerprinting can save up to 59% build time and up to 89% deployment time, while not affecting the container startup time.

    Is the Feature Traceability Problem Already Solved?
    (Softwaretechnik-Trends Band 44, Heft 2, 2024) Greiner, Sandra; Kehrer, Timo
    Reverse engineering feature information from a family of software products or configurable software projects is crucial to systematically support organized reuse. A feature represents a user-visible characteristic of the software which allows for its configuration; the resulting variable source code can optionally be included or may also have to be present in each variant of the software. Thus, tracing features to artifacts in the software project is essential to support systematic reuse. Existing solutions to the problem of identifying and mapping feature information in configurable software, either enforce specific development processes, rely on extensive executions of the software, remain coarse-grained at the level of files, or assume language-specific information. These issues raise the question whether the problem of identifying and mapping features to artifacts in configurable software is already sufficiently solved?

    Understanding the Re-Engineering of Variant-Rich Systems: An Empirical Work on Economics, Knowledge, Traceability, and Practices
    (Softwaretechnik-Trends Band 42, Heft 2, 2022) Krüger, Jacob
    Most modern software systems exist in different variants to address a variety of requirements, such as customer requests, regulations, or hardware restrictions. In this dissertation, we empirically study four closely related properties in the context of variant-rich systems, namely economics, knowledge, traceability, and practices. First, we contribute a rich dataset on the economics of (re-)engineering variant-rich systems, from which we derive the core insight that moving towards platform engineering (e.g., via more systematic clone management) is economically promising. Second, we contribute an understanding of developers memory and how to support their knowledge needs, leading to the core insight that expensive reco very activities can be mitigated by enforcing suitable documentation techniques (e.g., feature traceability). Third, we contribute insights on how different feature traces impact developers program comprehension, based on which our core insight is that feature traceabi lity should ideally be independent of configurability. Finally, we contribute a process model and recommendations on how to (re-)engineer variant-rich systems, with our core insight being that carefully planning and periodically assessing a variant-rich system helps to exploit its full potential (e.g., in terms of cost savings).

    Variant Analysis in Changing System Landscapes
    (Softwaretechnik-Trends Band 40, Heft 2, 2020) Tenev, Vasil L.; Becker, Martin
    In order to raise understanding of similarity in a set of related systems, the Variant Analysis approach has been developed and applied in various industrial settings over the last decade. The paper discusses typical analysis goals and the respective approaches. Additionally, it motivates the need for an incremental and iterative analysis approach to support settings, where the scope of the analysis changes over time. Examples to this end are adding, updating, or removing variants, versions, or system modules.
