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?

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!

Puppet + Razor = Good!

Razor installation using Puppet

node razor {

class { 'sudo':

config_file_replace => false,

}

include razor

}

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,

}
