The only difference is that Heat accepted 'Resource' as specific term for them (you see? they used broad term for their concept). So I am asking myself, where is difference between generic term Resource and Role? Why cannot we accept Roles? It's short, well describing...

+1 to Node Role. I agree that “role” is being used as a generic term here. I’m still convinced it’s important to use “Node” in the name since this is the item we are describing by assigning it a certain type of role.
