Cern has more than enough folks that have run systems that are harder to run cloud scale compute.

Even if running a DC is rocket science (it isn't), it is no particle physics.

The EU should absolutely have its own homegrown tech stack, from silicon to billing. I'd start with an EU run internet backbone and federated object storage in each member state.

CERN still runs on openstack for the non-specialised projects, I believe. They do improve the project, but it's not their own solution.

I can't see Gaia-x mentioning a ready solution anywhere and it seems very secret and proprietary for a project that's meant to be transparent, federated, and lunching end of this year. (Unless I missed something?)

If I rememberm AWS CTO is dutch. Throw €100bn in a tech fund and poach him or someone like him, give them free reign, done. Poverty of imagination and obsessive financial conservatism and control freakery from the euro investment community is the real problem, not lack of talent.

I'd be surprised if a decent AWS equivalent can't be built in 10-15B. That should be enough to hire good people and buy infrastructure. How do you figure 100B? It doesn't have to serve AWS traffic from day one...
