More specifically I've noticed less reliance on configuration management frameworks like puppet and chef. If you're building a container cloud, consisting of 'immutable' servers and a scheduler like kubernetes, then there's not much of a role left for one. You might use the lightweight versions (e.g. chef-solo) to bootstrap the servers, bake an AMI (or god forbid a container image). And you'll use something like cloudformation or terraform to configure the cloud. But if I'm going to toe the immutable infrastructure line I'm not going to use a config mgmt tool to update the state of my existing servers.
