Do you have any examples of poor tenant isolation in AWS, GCE, or Azure?

Cloud complexity is also lower because you don't have to worry about power, cooling, upstream connectivity, capacity budgeting, etc. If 99.9-99.95% availability is fine for your application then you probably don't have to worry about your provider either.

AWS Netflix consumes enough resources that if they spike 40-50% everyone is screwed. The software required to run the cloud like AWS is orders of magnitude more complex then what avg project would need and results in major screwups. Both major AWS outages were due control plane issues second case was result of massive Netflix migration that triggered throttles for everyone in affected AZs. The throttles in the first place were put in due to the major outage that lasted for many hours.

I hate to feed a troll, but ...

Noisy neighbors are a problem all the way from sharing a server using VMS to top of rack switches.

An if you try hard enough, you can always escape your VM and "read somebody else's mail."
