It's amazing how people complain about GCP. We run a massive deployment across 100+ regions cross-cloud GCP, Azure, AWS and oh boy. GCP has good support if you are big enough. Azure though which has a much bigger share than GCP is horrendous. Absolutely garbage all around. Good luck ever getting anyone in Engineering even if you are paying for support. AWS on the other hand - Amazing. We have Ent Support so those guys in our slack channel. The TAMs are amazing. Need to get hold of someone in Route53 no problem they are on the call this week. Feature request for EKS - ok talk to the Product Manager this afternoon.
Azure is a dumpster fire from the ground up.
