Why you should be there
EXPERIENCE HOW DIGITAL SOVEREIGNTY IS BUILT
More than 80% of digital infrastructure worldwide runs on Open Source — in the cloud, in private data centers, at the edge. The Sovereign Cloud Days bring together those who build, operate, and are responsible for this infrastructure. You can expect high-quality input from sovereign cloud to private infrastructure to sovereign AI on open platforms.
