It's worth considering why you are choosing a European stack.
Is it to support local/European companies - Great. Is it because you don't want to be at risk of the US and the CLOUD Act - Not so great. Any company that has servers in the US (which Hetzner and basically all CDNs do) are still vulnerable to the CLOUD Act and that includes servers in Europe.
I can tell you why. It's not the cost (even though it certainly helps)
For my company it's about the "pulling the plug" usecase. We create a SaaS product for semi-critical infrastructure - we don't need 99% uptime but more than a few hours and it's problematic.
Sure, most cloud/VPS providers have sites in the US as well, but worst case only those places would be affected if the US decided to do a Special Military Operation on Greenland for example.
That doesn't sound right. https://docs.hetzner.com/general/company-and-policy/data-pro...
If you spin up your servers in EU locations they are under German ownership and EU regulation. Others, such as those in the US, are owned by a subsidiary and those are subject separately on the Cloud Act. Correct me if I'm wrong.
