Google cloud takes better care of their big customers. But they have a branding problem. Perhaps they should rename it alphabet cloud or something.
(just finished moving a client's last GCP env from an acquisition to AWS)
I don't know what the equivalent GCP spend would be to get similar treatment. Presumably higher. So that's a data point, at least.
You have to respect your customer, the work they did and organizational constraints when you are coming in to a large company.
