Bjorna Kalaja – Measuring the carbon footprint of microservice architectures

In this session I would like to provide insights on state of the art solutions on how to measure carbon footprint of a software solution.

Content of the session will include:

• To set the context, a short introduction to scope 1, 2, 3 emissions and why it is important to be able to track emissions of a software solution, will be provided
• challenges that we face as an industry that make theses measurements difficult
• what metrics are used
• and what tools and processes are currently present in the state of the art that enable measuring and tracking carbon footprint of software applications in a microservice architecture

This session will also contain a live demo how to measure and visualize the carbon footprint using two different tools.

Maël Madon presented their Reflections on sufficiency for data centers: I am a researcher in Computer Science, with an interest in environmental impacts of computing. In this talk, I want to share with you some insights from my PhD work, in which we tried to go beyond efficiency measures for data centers, and rather think about sufficiency. I will explain how we approached the problem, give some results and also personal thoughts on the question.

Crisis counseling for Windows 10 users: Bring your questions (and if you want, computer) if you are affected by Microsoft's declared end of the support of Windows 10. Together we can talk about our options in this situation (Do I need a new computer? Are there alternative ways out? etc.) and you can also try out free alternatives to Windows, if you like!

Afterwards we'll watch a recording of the talk Permacomputing 101 by Devine from Hundred Rabbits, recently presented at Critical Signals 2025, and have a bit of talk and discussion around it.

This time around we will evaluate the digitalization strategy of the freshly appointed new austrian government (NEOSPÖVP), of course with a focus on matters of sustainability! To do so we will (among others) take a look at page 179ff in this pdf with the fateful title Microsoft Word — Regierungsprogramm.docx. Nomen est omen? We'll see.
