You hit every high point of my own experience but there are caveats. 1. If you have to do on prem then virtualize and package till you can wash, rinse repeat. 2. Secure systems with k8s are a thing: Stigged k8s, stigged host systems, mtls, psp, network policy, MAC integration - this makes k8s really unpleasant to deal with if you come from pub cloud, pub k8s provider. See #1. 3. Performance: dns sucks and it sucks for all kinds of reasons: usually avoidable with node local caching approaches, but sometimes not. 4. Yes: Big clusters...until you need federation.
