● Models (Defining OS Templates, ...)
● Policies (Rules that apply Models to Nodes based on Discovery)
● Broker (Configuration Management)

21. Razor DEMO
DISCOVERY
● PXE boot
● Microkernel
● Facter
● Communication

22. Razor DEMO
MODELS
● Operating System templates
CentOS/RHEL6 – Ubuntu Precise/Oneric – openSUSE – Debian
VMWare ESXi 5
● Kickstart / preseed / ...
● Variables (Hostname, domainname, password, ...)

● Drink coffee :­)
● When deployed, node gets delivered to the “Broker”
(Chef,puppet,...) for future management.
