Nope. If the clusters are separate it limits how damaging a compromise of the cluster is. This is why cloud providers don’t stick you on the same k8s cluster as another tenant.
> Multiple clusters may have a smaller blast radius, but will have a larger attack surface. Things may be shared between them (accounts? network tunnels? credentials to a shared service?) in which case an intrusion in one puts everyone else at risk.
It’s not really clear what you’re trying to say here. If someone compromises credentials shared between all clusters that’s the same as compromising credentials used by one mega cluster.
