Europe is moving decisively away from U.S. tech giants toward open-source alternatives, driven by concerns over digital sovereignty and reliability of American companies[1]. At the 2025 OpenInfra Summit Europe, industry leaders emphasized that this shift isn’t about isolation but resilience.
“What we’re really looking for is resilience. What we want for our countries, for our companies, for ourselves, is resilience in the face of unforeseen events in a fast-changing world. Open source allows us to be sovereign without being isolated,” said OpenInfra Foundation general manager Thierry Carrez[1:1].
This transition is already happening. The German state Schleswig-Holstein has replaced Microsoft Exchange and Outlook with open-source email solutions. Similar moves have been made by the Austrian military, Danish government organizations, and the French city of Lyon[1:2].
European companies are stepping up to fill the gap with open-source alternatives, including:
- Deutsche Telekom’s Open Telekom Cloud
- OVHcloud’s sovereign cloud services
- STACKIT and VanillaCore’s European-based offerings[1:3]
The movement gained additional momentum when the European Commission appointed its first executive vice president for tech sovereignty, security, and democracy in 2024[1:4].
I’m interested to see what an open source cloud standard would look like. There’s a lot of elements that share functionality between Azure and AWS, but they’re just different enough that it’s a massive pain in the arse to move from one to the other and you basically have to re-write your Terraform from scratch.
If there was something that was standard so I could write Terraform that goes “I want thirteen microservices all running in docker containers and a message bus with these types of message that lets them communicate” without specifying the exact implementation, I would be a happy camper.
Maybe something like OpenStack?
This is basically kubernetes with a couple of custom resource definitions, no?
nix?
