So what’s Razor?
Cloud provisioning tool
Operating Systems AND Hypervisors
Physical AND virtual
Event-driven instead of user-driven

Why not just use templates?
They get old fast
Pre-packages bits are harder to maintain
No easy upgrade to next distro version

So how does it work?
6© Copyright 2012 EMC Corporation. All rights reserved.
Auto-Discovered Real-Time Inventory Data
Boots a Micro-Kernel
Primarily using facter
For every hardware node
Eliminating inefficient, error-prone manual processes
Full insight into the latest, up-to-date status of your hardware inventory
7© Copyright 2012 EMC Corporation. All rights reserved.
Dynamic Image Selection
Selects the correct operating system image
Based on auto-discovered, real-time inventory data
No manual intervention needed
8© Copyright 2012 EMC Corporation. All rights reserved.
Model-Based Provisioning
Models the desired state of each hardware node and its operating system
Automatically tracks provisioning progress toward this state
Full control over a node’s boot sequence and a complete log of its lifecycle
9© Copyright 2012 EMC Corporation. All rights reserved.
Open APIs and Plug-in Architecture
RESTful open APIs
Full programmatic control of the rules and models that govern operating system image selection and hardware provisioning
Enables the Puppet community to collaborate and share plug-ins to support any operating system and any boot sequence

Metal-to-Cloud Application Lifecycle Management
No need for siloed management tools!

}

Add a broker
rz_broker { 'puppet_broker':
ensure => present,
plugin => 'puppet',
metadata => {
broker_version => '2.7.18',
server => 'puppet.purevirtual.lab',
}
}
14© Copyright 2012 EMC Corporation. All rights reserved.
Add an image to deploy
rz_image { "ubuntu_precise_image":
ensure => present,
type => 'os',
version => '12.04.1',
source => "http://ftp.sunet.se/pub/os/Linux/distributions/ubuntu/ubuntu-cd/12.04.1/ubuntu-12.04.1-server-amd64.iso",
}
15© Copyright 2012 EMC Corporation. All rights reserved.
Add a model for deployment
rz_model { 'install_ubuntu_precise':
ensure => present,
description => 'Ubuntu Precise',
image => 'ubuntu_precise_image',
metadata => {'domainname' => 'purevirtual.lab', 'hostname_prefix' => 'ubuntu-', 'root_password' => 'password'},
template => 'ubuntu_precise',
}
16© Copyright 2012 EMC Corporation. All rights reserved.
Finally, create a policy to tie it all together
rz_policy { 'ubuntu_precise_policy':
ensure => present,
broker => 'puppet_broker',
model => 'install_ubuntu_precise',
enabled => 'true',
tags => ['memsize_1GiB'],
template => 'linux_deploy',
maximum => 10,
}
