I have a hosted chef account working with AWS EC2 instances.
The instances can connect to hosted chef by way of chef-client and run the inital
run_list that is presetly a role called servers. Everything runs and installs
correctly on initial provision.
I should also mention I have autoscaling on ec2 instances that increses the amount of instances
provisioned on an 'as needed' basis and this works fine.
I found one talk that sort of makes sense but seems a bit more involved.

My questions are around how to maintain the servers after initial provisioning. First, if I have an update to my role to include more cookbooks or configuration, and how would I push this out to say X amount servers in a simple way.
Second, how would chef server know if a node has failed and notify the admin?
Any guidance?
