If you are consistent in your use of puppet you can use puppet as a documentation resource. Need to know how a particular server is configured? Look at the puppetcode! With puppet you can move servers with ease! you write generic classes or modules. Need to move a particular service? Just include it somewhere else! For consistency it's really easy to apply the same configuration to a lot of hosts. Need to add a host? Well, just add it to the host group, and puppet takes care of it! As for administration overhead. Puppet will give you less work to do! How? You just make a puppet manifest/module/class/whatever suites you that takes care of a certain thing. You know it works! You don't have to remember how. Next time, just apply it to a host! And Done! If you need scripts to work on multiple platforms, Puppet does this really well. Just add eg a case statement selecting what to apply based on operating system. Puppet scales well. Having server being puppetmaster set up with nginx/mongrel/puppet we can restart puppet 100 nodes at the same time having no troubles at all. The server being a dual quadcore with 16 gb of ram is serving approx 200 nodes and is not sweating a bit. Could easly serve the double. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
