Emerging Trends, Challenges, and Experiences in DevOps and Microservice APIs

In August 2019, we organized the second Vienna Software Seminar (VSS) with the topic "DevOps and Microservice APIs.1 Embracing the positive reception of its first iteration in 2017,2 VSS is an opportunity for attendees to discuss recent software technologies, practices, and related research. The seminar's 34 participants included a mix of practitioners and academics, who were invited based on their roles and experiences. The explicit intention of the seminar was to provide ample opportunities for exchange and communication: six themed sessions consisted of one invited keynote and two lightning talks, giving different perspectives on the session?s topic and (ideally) sparking ideas for follow-up discussions. After the talks, all participants decided on subtopics for two to three breakout sessions (i.e., informal, self-organized discussions among interested participants). Breakout session topics included microservice security, tooling for application programming interface (API) evolution, serverless programming models, and identification of microservices using domaindriven design. The sessions provided opportunities for detailed discussions and identifying challenges to address in future collaborations. Toward the end of each session, all participants gathered once more to summarize the breakout discussions. Additional opportunities for communication were provided during shared lunch breaks and social events in the evenings. © 1984-2012 IEEE.
