There are about 6-7 euro companies that seem to have this long term plan of becoming the euro AWS (including OVH) but the problem is always the capital available.

I use AWS at work and it can become insanely complex to work with, or to have estimates or what's going to cost you.

I did use scaleway in my previous work (they didn't have as many services as they have now) and it was much easier.

Anyway, there's still a long way to go because these services need to catch up with the AWS offering and pretty much everyone knows AWS, it's the default now.

If I had to start a business now I would probably go with Scaleway.
