A Blog of the ZHAW Zurich University of Applied Sciences
In a previous blog post, we described our experience with deploying OpenWhisk on Kubernetes on OpenStack. During subsequent testing, we observed some issues with the OpenWhisk deployment wherein some OpenWhisk components – specifically, the controller and the invoker – would fail to restart after rebooting the machines running the Kubernetes nodes for maintenance tasks. To […]
Serverless applications is one topic that SPLab has been working on for a couple of years now, with, for example, our work on a stand-alone FaaS platform Snafu, work on disaggregating applications into serverless functions, Podilizer and other activities. Having organised ESSCA some weeks ago, we are now again exploring the technical limits and challenges […]
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), […]
For almost five years, we have been researching cloud-native applications. As part of an industry-wide push to cloud-native computing, a lot of stacks and middleware components are proposed every day, but few tools and processes help improving the applications themselves especially in terms of quality attributes such as discoverability, elasticity and resilience. With Helm charts, […]
From the 10th until 13th of December 2018 in Nicosia, Cyprus, the 10th IEEE International Conference on Cloud Computing Technology and Science took place. This slightly delayed conference report briefly recapitulates the event from our subjective participation perspective. Schlagwörter: cloud accounting, conference, multi-cloud, paper
In our research group, we have for many years observed and systematically explored how cloud applications are being developed. In particular, we focus our investigations on cloud-native applications whose properties are largely determined by exploiting the capabilities of modern cloud platforms for both their development and operation. As we are involved in European research on […]
Our SPLab organised a full day workshop on cloud-native applications (see the web page and call for papers of the CNAX 2018) within the IEEE/ACM UCC/BDCAT 2018 umbrella. The workshop was organised in collaboration with Ivo Krka from Google and also supported by Jorge Cardoso from Huawei. The blending of industry and academic research has always been […]
In recent months, we have extensively studied Helm charts, including setting up a continuous quality assessment, to find out more about this promising packaging format for Kubernetes applications. Apart from individual tweets and occasional talks, there was a lack of a coherent presentation of the ongoing work. Yet, due to the increasing installation base of […]
From December 17 to 20, 2018, our lab proudly hosted the 11th IEEE/ACM International Conference on Utility and Cloud Computing (UCC) along with its collocated event 5th IEEE/ACM International Conference on Big Data Computing, Applications and Technologies (BDCAT). We welcomed around 200 attendees in the Zurich Technopark, making it a record event in the multi-year […]
Through several years of research on the subject of cloud functions, researchers including ourselves have gained a thorough understanding of the advantages and disadvantages of function-based application development. Along with increased maturity of FaaS, a more specialised consideration of potential use cases is needed to filter out the ones where the technology shines compared to […]
