[...] RightScale ServerTemplate Library and Machine TagsTags! "We introduced Flickr style machine tags recently and we’re expanding their use with this release. One of the really exciting new features is that servers now have tags and we’ve integrated the tags with the routing of messages between servers, with Chef (via the RightLink agents) and with the UI. All this is still in alpha but it’s starting to take shape. Our first real use-case is the registration of application servers with load balancers. The way it works is that when a load balancer comes up and is ready for operation it adds a “loadbalancer:lb=www” tag to say “I’m a load balancer for the www vhost”. When an app server starts up, it requests all servers in the deployment with a “loadbalancer:lb=www” tag to run a Chef recipe that adds the app server to the load balancer rotation. This way, the app server doesn’t need to know which or how many load balancers there are. The tag matching, communication, and running of the Chef recipe are all done by the RightLink agents." [...]
