Economy and society in Switzerland are currently highly affected by the spreading second version of the coronavirus (SARS-CoV-2) that causes the associated infectious desease (COVID-19). The World Health Organisation (WHO) has classified the virus outbreak as PHEIC on January 30 and as pandemy on March 11. In Switzerland, the state emergency level Eminent/Special Situation was reached on February 28, and further restrictions led de-facto to the subsequent level Extraordinary Situation on March 13. This blog post reports on how the outbreak evolution can be continuously visualised as a reliable service with off-the-shelf tools.
With the proliferation of hybrid cloud, cross-cloud and post-cloud environments, finding the right concepts and tools to produce mixed-technology applications and services remains challenging. At Zurich University of Applied Sciences, a course on Serverless and Cloud-native Application Development (SCAD) prepares bachelor students in computer science for facing these challenges. We argue that this is the first such lecture in Switzerland and probably even in the world. Three years after reflecting on Internet Service Prototyping teaching, this mid-semester blog post sums up the evolution of the field, explains the course design of SCAD and briefly reports on the lab results.
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.
The University of Sharjah is the national university of the Emirate of Sharjah in the UAE. Located in the University City, the world’s largest campus, its buildings convey the uniqueness that underpins its research activities, including in computer science and engineering. We are proud to have started cooperative research and the exchange of researchers many months ago. In this blog post, our latest joint work on multi-paradigm computating in a trilateral constellation with Penta is presented.
From September 2 to 4, 2019, Tampere University hosted the INFORTE.fi-supported summer school on Software Evolution: From Monolithic to Cloud-Native. The Service Prototyping Lab at Zurich University of Applied Sciences contributed with five lectures (and one coincidental serverless meetup talk) to increase theoretic knowledge and practical skills of Finnish doctoral students and developers on microservices and software engineering for the cloud. All presentations are available online but as usual the slides do not capture discussions and industry relevance, so read on to get to know more about this.
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.
Bachelor students of computer science at Zurich University of Applied Sciences focus a lot on software development. Software is never developed in the blue; rather, software needs a concrete environment to function and to deliver value. In ‘Programming’ (1st/2nd semester) and ‘Software Development’ (3rd/4th semester), you learn some basic skills. In ‘Systems-oriented Programming’ (2nd semester), you apply these skills to predefined systems with some constraints. In ‘Web Development’ (3rd semester), you apply these skills to another environment in which there is a lot of pace through new technologies. In ‘Game Development’ (5th semester), you develop for specific interactive scenarios, and in ‘Mobile Applications’ (5th semester, you develop user-facing apps for common mobile platforms.
One of the most fascinating and economically important areas is the development of applications which run in the cloud. You may access them with web or mobile devices, but you still cannot see them! Still, they are very powerful, scalable to millions of users, and interconnected across cloud providers and with various backend systems such as databases, message queues and key-value stores. This is why we offer SCAD, a new elective module on Serverless and Cloud-native Application Development.
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.
On July 31 and August 1/2, purposefully disregarding the Swiss national holiday, the Service Prototyping Lab at Zurich University of Applied Sciences was represented at the premises of the Indian Institute of Technology, the former Indian School of Mines, in Dhanbad, the most populous city in the northeastern Indian state Jharkhand. Although the area is traditionally known for its coal and minerals industry, IIT (ISM) Dhanbad is also offering teaching, research and academic services including conference organisation in computer science fields. This matching profile with overlapping areas has triggered our interest, and thus Josef Spillner made the trip to offer guest lectures, tutorials and faculty-level discussions about future exchanges. This article reports on the days spent in Dhanbad.
