We’ve all heard the complaint: When you move into a public cloud, you experience performance issues caused by others being on the same public cloud, in what’s often called the “noisy neighbor” problem.
It seems reasonable to make this claim, given that public clouds are multitenant beasts, so you’re sharing resources with other cloud users. That sharing means you’re also competing for the same dedicated servers back in the cloud provider’s data center, right?
The reality is different, as we can see as more and more applications move into their second and third years of production on public clouds. You simply don’t hear of performance problems caused by contention with other cloud tenants. The multitenant factor that scared the hell out of traditional IT shops does not seem to be a real issue.
