 What are the new key use cases that either you're excited about or worried about? I mean to stay on topic with the open stack question like the the topic of NFV you know network virtualization is a really challenging topic. There's a lot of people out there who have built solutions around the idea of NFV and a lot of enterprises who are building their security policies or their infrastructure stacks around how NFV works. Kubernetes doesn't have an NFV model it has a very flat network model so we're having a lot of discussion for quite a long time about should we adopt a multi-network model should we model it as networks we model it as resources should we model it statically or dynamically well how does hardware fit into this how does virtual software fit into this it's a very challenging topic where you know basically for every sort of feature intersection there's somebody who wants that and we're trying to limit the scope and figure out should we do this how should we do this and how deeply should we do this right
