In U.S , one way or another everything is running in the cloud.
For Europe ? It’s more complicated , most large businesses still have their own datacenters or run using dedicated machine with European hosting (OVH).
I’ve worked for many differents banks and they barely use the cloud compared to startups like N26 or Revolut.
Same thing for Industries or Health Services they largely run « On Premise » compared to U.S equivalent.
There is still room for growth from Europe if they manage to convince leaders of large corporations that the cloud will not take the their sovereignty away from them .
