Operational open source technology

Talk is silver, development is gold: we are passionate doers. That's why at ALASCA we create real, operational technologies for cloud infrastructures. 100% open source. 100% ready-to-use.

Knowledge transfer

We create the right framework for the active exchange of knowledge and experience between our members and beyond the boundaries of the association. In various event formats (e.g. hackathons, webinars or tech talks), we drive the identification, further development and publication of free cloud projects and their potential.

Multifaceted competences

Concentrated power: Our members combine their different experiences and skills into collaborative project work. In this way, we are able to move forward open-source projects for cloud infrastructures together.

Strong community

Our community is characterized not only by its competencies, but especially by enthusiasm, curiosity and passion for open-source. We live an open and respectful cooperation. We also strongly network with other communities in the European open-source landscape beyond the association's borders.

Our history

Since the end of 2020, Cloud&Heat Technologies and STACKIT have been developing the jointly initiated open-source lifecycle tool Yaook. To date, the Yaook community has grown to around 50 members from different companies - and the trend is rising. In order to decouple the project from individual companies and to be able to develop and advance it more independently, the desire grew to put Yaook on its own feet. At the same time, the call from business and the public sector for open-source tools to achieve digital sovereignty and to make them known beyond the boundaries of the developer community grew louder and louder. The idea for ALASCA was born!

As the first ever project, Yaook brings ALASCA to life. But this should not remain the only project. Instead, we want to attract further ones - whether newly initiated or already existing - and create the right environment for their successful development. And not only that: We also want to promote exchange between the members and beyond the ALASCA borders - all this for European Digital Sovereignty.
