6.  Open source systems integration framework
by Opscode
 System configuration as source code
◦ Configuration Template w/ Business Logic
◦ Describe infrastructure
◦ Establish relationships between boxes
 When a new server comes online, all you
need to do is tell Chef what role(s) it plays in
your architecture. All other servers will adjust
their configuration automatically to welcome
the new member to the fold!!!
