Adaptivity and adaptability are key characteristics of modern software to cope with sometimes unpredictable changes in the environment including system and user behaviour. Modern cloud-native architectures for instance foresee the case-by-case handling of decisions – e.g. to decide whether using a provider database or hosting one yourself – at the application or workflow level based on knowledge and rules or emergent behaviour. In workflows representing data flows from connected devices, the (self-)adaptivity should be modelled and supported by context-aware systems.
As reported before, we investigate quality characteristics of decentralised applications in analogy to the usual assessment of microservice artefacts. We are happy to report on how we shared the intermediate results at the most recent Azure Blockchain meetup in Zurich, apart from reporting on the event itself.
The eternal software circle of life continues to pose non-trivial challenges. Developers write code, run tests, push and/or deploy, perhaps leading to more tests, and finally see their software used in production. Eventually, they might see everything working out correctly or rather not, as indicated by log messages, user complaints and other side channels, and even more eventually, when nothing else gets in the way, they might even attempt to fix the problem at any code location which might have a probability of contributing to the issue.
AWS Cloud Summer School Switzerland was scheduled as a five-day event organized by Amazon. The event took place from September 3 – 7, 2018 in Zurich, Switzerland. From the outline, it appeared worth attending as it offered high-quality educational modules and hands-on labs. The SPLab was thus present at the event and this blog post aims to briefly summarize what took place and what implications can be inferred for the near future of cloud applications. Continue reading
At the Service Prototyping Lab, we were honoured to receive the fourth international speaker in our colloquium series this year. Christopher Hauser presented the ongoing research at Ulm University, specifically in the Institute of Information Resource Management whose research is centered on loosely and tightly coupled systems. The colloquium speaker focused more on the former and hence presented his talk «Research and Interests» with emphasis on cloud computing and heterogeneous systems. The main points of interest arising from the talk and the discussion are summarised in this article.
