It's astounding how much of Kubernetes is simply marketing. Google doesn't even use it internally.
Service Fabric[0] is leagues ahead of any cluster orchestration framework, heck, it's a complete distributed systems platform which powers all critical Azure services (Cosmos DB, Cortana, SQL DB). It is the only framework that allows native stateful applications; your state doesn't need to be delegated to another service. It offers Reliable Collections (Java and C#) which are persistent, replicated and sharded native collections.

I wish more devs knew about SF.
