Sustainable Kubernetes – Scale up, Scale down, Scale to Zero

May 16, 2023

As a distributed system, Kubernetes offers the option of automatically scaling applications horizontally. This allows the application to be dynamically adapted to actual requirements. The cluster itself can also be scaled with corresponding hyperscalers. In combination, computing power can be released or added as required. This saves resources and money. At the same time, such a configuration is well prepared for peak loads.

Sustainability thinks ahead – how can we implement scaling from an ecological perspective? Especially applications that are not permanently under load should be switched off when not in use. And the challenge is to switch the application back on. Zero becomes Hero.

Lukas shows us from practical experience with live examples where the fall strikes are and how to use them sensibly. This presentation highlights the benefits and risks of scaling and aims to encourage reflection on the resources used.

Lukas Paluch works at ATIX AG as an IT consultant in the container sector. He provides support both in setting up the platforms and in migrating applications.

UIG Conference 2022

September 22, 2022

Digitalization has become an integral part of all areas of life. Many companies have recognized the importance of usability and user experience (UUX) as a decisive competitive advantage for successful digitalization. However, the consistent implementation of human-centric digitalization also means that all people have unrestricted access to digital technologies and that digital technologies also reflect the diversity of our society.

At the UIG Conference 2022, experts from science and practice discussed how digital inclusion can be successfully implemented as an integral part of good usability and a positive user experience. It was of particular interest to network medium-sized companies and UUX service providers.
