SPLab Colloquium on Robust Modern API Design

by Josef Spillner

In the second invited talk in our colloquium series in 2018, Alan Sill from Texas Tech University’s Cloud and Autonomic Computing Center shared his views on how to manage data centres the right way. In the talk «Topics in robust modern API design for data center control and scientific applications», many issues were pointed out whose proper solution will effect the whole cloud stack up to the way cloud-native applications are designed and equipped with deep self-management capabilities. Both the talk and the mixed-in debates are captured by this blog post.

Portable Cloud Functions for Future-Proof Software Applications

by Josef Spillner

Ever since the inception of cloud computing as a widespread phenomenon over a decade ago, the issue of API and data structure variety across providers has become a major hurdle to multi-cloud applications. Even in the most recent services such as Function-as-a-Service (FaaS) offerings to build so-called serverless applications, the issue repeats itself with each provider pushing for their own management interfaces and accepted function definitions.

Yessica Bogado and Walter Benítez from Itaipu Technology Park, currently visiting the Service Prototyping Lab at Zurich University of Applied Sciences, are among the active researchers who tackle such practical problems from the perspective of engineering software applications based on microservices. In the park’s distributed systems and parallel computing research team led by Fabio López Pires, they are witnessing first hand the increasing issues of local software and service providers to keep up with cloud trends. Appropriate tooling can therefore help to alleviate the issues. This blog post describes one such tool, the FaaS converter, which has emerged from their applied research. Continue reading

Impressions from Swiss Python Summit 2018

by Josef Spillner

The third Swiss Python Summit took place in Rapperswil, Switzerland, today. Conveniently located about an hour drive from the Service Prototyping Lab at Zurich University of Applied Sciences, the event reserved a spot on our conferences shortlist this year. In this post, we will briefly summarise major impressions from the well-organised summit.

SPLab Colloquium on Serverless Scientific Computing

by Josef Spillner

Maciej Malawski from AGH University of Science and Technology in Kraków, Poland, visited us today to give a colloquium talk titled «Can we use Serverless Architectures and Highly-elastic Cloud Infrastructures for Scientific Computing?» and to discuss research around the wider topics of workflows and cloud function compositions. This post summarises the talk and the subsequent discussion mixed with further general reflections on the state of serverless applications.

Visitors from Itaipu Technology Park

by Josef Spillner

Following up on the previous visit from Service Prototyping Lab (SPLab) at Zurich University of Applied Sciences in Switzerland to Itaipu Technology Park (PTI) in Paraguay, two young investigators from PTI’s Centre of Information and Communication Technology (CTIC) with support from CONACYT are now visiting us at the SPLab and more generally in Switzerland.

Yessica Bogado and Walter Benítez will spend some weeks to get to know the local research and development situation, get information about our ongoing research initiatives, dive into solving some hard questions, and discuss ideas for future collaboration. Furthermore, they will explore novel research methods and prototypes specifically in emerging technology areas such as cloud-native applications and serverless applications, as well as upcoming hybrid container/cloud function applications.

Vienna Software Seminar: DevOps and Continuous-*

by Josef Spillner

Vienna, the second-largest city in the German-speaking world, had become a meeting place earlier this week for software and service engineers who explore the crossroads of software architecture, DevOps processes and continuous-* (software development, integration, delivery) approaches. The 1st Vienna Software Seminar had mixed business and academic participants and has been of particular interest to architects and practitioners who want to migrate applications or related processes into cloud environments and are in need of relevant methods and tools. With its interactive agile format and focus on break-out groups, the seminar was structured so that topics could be discussed in detail and grouped by interest. This report summarises the four-day event including some highlights from selected discussions from a participant perspective.

Extending Web Applications with Cloud Functions

by Josef Spillner

The discourse on cloud functions focuses heavily on diverse use cases: Standalone functions to perform a certain functionality, compositions of functions into complete applications, and functions as plumbing between separate application parts. This blog post intends to explore the use of cloud functions as extensibility mechanism for existing applications. It exemplifies the interaction between a function, a website and a login-protected web application and furthermore discusses implementation aspects and the notion of caching data in function instances.

Guest Researchers from Mozambique

by Josef Spillner

In the final days of October, the Service Prototyping Lab at Zurich University of Applied Sciences (ZHAW) hosted two doctoral candidates who take part in the structured doctoral programme Information Technology and Systems at Universidade Eduardo Mondlane (UEM) in Maputo, the capital of Mozambique. The candidates Martina Barros and Ambrósio Vumo arrived from Germany, as they spent a significant part of their research time at Technische Universität Dresden (TUD) as part of the DAAD-funded joint programme Welcome to Africa. The realisation of this programme also involves the Service Prototyping Lab as competence centre for research and innovation on cloud applications and new services for digital economies. This article describes how innovation transfer was conducted during the stay.

ESOCC 2017 – Oslo

by Josef Spillner

The past 27, 28 and 29 of September were dedicated to the 6th European Conference on Service-Oriented and Cloud Computing (ESOCC) in Oslo, Norway. It is one of the traditional community-run conferences in Europe with a cloud and community history dating back into the year 2012 and a (web) service history of about a decade before that. As in previous years, it featured the co-located event CloudWays: the 3rd International Workshop on Cloud Adoption and Migration, which is focused on cloud applications more than on infrastructure and platforms. The topic is thus of high interest for the Service Prototyping Lab and specially for its Cloud-Native Applications (CNA) research initiative in which we partner with Swiss SMEs to explore new cloud-native designs and architectures for elastically scalable, resilient, price-efficient and portable services. Our participation was therefore centered around the presentation of research results from one of these partnerships.

Probabilistically Stateful Serverless Web Applications

by Josef Spillner

Among the lectures offered by the Service Prototyping Lab is Scripting. Aimed at students of advanced studies, it teaches essential practical programming skills and conveys approaches how to automate the exploration of data retrieved from the Internet. Python is taught as programming languages and consequently a Python (Django) web application has thus far been used to automatically score the results submitted by students of a particular advanced task towards the end of the lecture. There’s nothing wrong with Django per se, but its roots have evidently been in the era of monolithic web applications. Armored with our Function-as-a-Service experience we decided to drop it and go purely serverless. In production.
