Azure has had multiple embarrassingly bad tenant-boundary leaks, including stuff like being able to access another customer’s metadata service, including credentials, just by changing a port number. They clearly have some major issues with lack of internal architecture review.
I have used Azure, AWS and GCP. The only reason people use Azure is because others force them to. It’s an extremely shitty cloud product. They pretend to compete with AWS but aren’t even as good as GCP.
I don’t think GPC has that reputation compared to AWS or Azure. They aren’t at the same level.
