| Hi! Actually in an upcoming release of Chef, you'll be able to do exactly that - manage Rackspace cloud nodes with the knife command-line tool. What that means is, you can launch new RS Cloud servers with knife, passing in the validation certificate and a run_list of recipes. For EC2, Opscode provides a reference AMI with Chef pre-installed on Ubuntu 9.10 with a special configuration file that can parse EC2 metadata through Ohai to automatically validate and run a set of recipes. See: http://wiki.opscode.com/display/chef/Amazon+EC2+AMIs+and+Che... One of Chef's benefits for managing a dynamic environments is the Search Index feature, which can be used to search for other nodes that have particular roles or attributes set. That is part of what the application cookbook does to dynamically deploy and connect with other systems running services like memcached or mysql. As for the learning curve and getting up to speed, that varies by person. Sincerely,
Joshua Timberman - Opscode, Inc. |
