44. - Configuration as Code
- Client-only or Client-Server setup
- backed by companies
- officially supported by Amazon
- tried and tested
- good documentation
- good, vibrant communities

45. - Chef is ruby code, puppet has a DSL
- puppet has the bigger community
- puppet has more documentation
- but chef is catching up
- puppet: europe, chef: USA
- chef is more flexible
- if you puppet, you don't know ruby
and vice versa
Mayflower GmbH I 45
46. - both know current configuration
- you define your nodes (servers)
- lots of community cookbooks/modules
- easy to extend
- templates
- providers as platform abstractions
(e.g. apt-get/ports/yum)
