COSCUP 2026 開源人年會

Europe isn't just talking about digital sovereignty anymore. Governments are actually doing it. Schleswig-Holstein is moving 30,000 workstations off Microsoft. France is deploying open source productivity stacks across ministries. Denmark, the ICC, universities, hospitals — the list keeps growing. And at the center of most of these migrations sit open source tools like Libre Office, Nextcloud and more.

This talk is about what these migrations really look like in practice — the architecture decisions (why Hub over Suite matters), the deployment realities (self-hosted, air-gapped, sovereign cloud), the partner ecosystem that makes it function, and the things that go wrong that nobody puts in the press release.

But this isn't a Europe talk at a European conference. This is a Europe talk at an Asian conference, and that's the point. Taiwan, Japan, Korea, India, and more; Every country in this room is navigating some version of the same question: how dependent are we on infrastructure we don't control? Europe is five years ahead on this journey. Some of what they (and we) have learned is directly transferable. Some of it isn't. I want to bring that honest conversation to COSCUP: What works, what doesn't, and what your community can start doing now rather than waiting for policy to catch up.
