Subject

Issue Management for Component-based and Service-oriented Systems

The emerging microservice architecture style gained more and more popularity. As a result, software development often follows such a component-based architecture style. As multiple teams are involved in developing such component-based applications, new software engineering processes have to be applied. Often, issues are propagated to other components (and their teams) and, therefore, affecting several components. For instance, a bug in a component interface can influence the dependent components. However, the current state of the issue management systems manages issues only in a component-specific scope. Therefore, state-of-the-art issue management systems cannot represent dependencies between issues of different components.

To handle this problem and improve software engineering for component-based systems, a concept for issue management in such systems has to be developed. Therefore, I aim to find methods to manage component-based issues efficiently and effectively and enable additional improvements for the software engineering process, such as insurance of QoS properties through issues. In the scope of this work, Gropius, a system to manage cross-component issues was designed. Gropius acts as a wrapper over the individual independent issue management systems of the components.

Furthermore, the management of cross-component issues enables several additional for the development of a component-based system, e.g. automated SLA-driven issue creation or performance insurance.
