Microservices in Numbers: Diagnostic Docker Deep Dive (Online Tutorial at CLOSER 2020)

16. April 2020 / Josef Spillner / 0 Comments

Cloud applications are typically designed as coupled microservices and deployed in managed containerised form. Industry trends around container build processes, deployment packages, management platforms and abstractions (e.g. cloud functions) are still fast-paced. Developers and operators need to be able to tell good from bad practices based on automatically determined metrics. Assuming they participate in this tutorial, they will learn how to do that on a hands-on level. We introduce approaches and open source tools for quantitative assessment of containers and other microservice technologies and ecosystems. On the research side, we explain how this blends with policy-driven deployments, trusted cloud execution and data science opportunities.

The three-hours tutorial will be offered at the CLOSER 2020 conference (originally scheduled in Prague, now online) in the afternoon on May 7. Registration information is available from the conference website.

Building a Singer.io tap for an open data source

20. December 2019 / boru / 7 Comments

Singer.io is an open-source JSON-based data shifting (ETL: extract, transform, load) framework, designed to bring simplicity when moving data between a source and a destination service on the Internet. In this post, we present the framework as entry point into the world of SaaS-level data exchange and some associated research questions.

Insights into AWS SAR

13. May 2019 / Josef Spillner / 0 Comments

The Serverless Application Repository by Amazon Web Services (AWS SAR) is, in simplified terms, a marketplace for Lambda functions. You can speed up application development by building on the functions (or function compositions) provided by it, and you can share your own functions with other cloud application developers. AWS SAR was launched over a year ago. In the Service Prototyping Lab at Zurich University of Applied Sciences, we are investigating better ways of building applications for cloud and post-cloud environments. Consequently, we did a full year observation of AWS SAR to find out what’s in it and what’s going on. Read on for some interesting excerpts and findings and for accessing the study document.
