I started to use tags with Spiceweasel for labeling "clusters" of machines. Turns out the tag option isn't supported by knife openstack/rackspace/hp so I shelved that in favor of using Environments for now. But I did open this ticket, which I'll fix soonish that will allow tag creation with all knife cloud plugins.

I've considered tagging for this. My biggest fear is that someone who doesn't understand their purpose will monkey with or delete them without realizing that code logic is tied to them. This fear has kept me from using them so far.

We have been refactoring our cookbooks to locate other nodes/services using Tags instead of searching for a Role or Recipe in the run_list.  This gives us some useful capabilities…  Instead of your load balancer searching by Role/Recipe and immediately discovering in your new node, you can validate the node before adding the Tag to it and bringing it in to production.  Or vice-versa, you could pull a node from the LB pool without modifying its run_list by simply removing the Tag.  The same could be achieved by using a custom Attribute, but Tags are convenient.

Node tags are one of those things I've never really had an opportunity to use. I've always used roles for the sort of use cases that tags seem to be made for. They were brought up in a conversation I had recently, however, which got me wondering... what real world uses have people found for node tags?
