2. What is Puppet?
IT automation software
Helps system administrators manage
infrastructure throughout its lifecycle
Provisioning and configuration
Patch management and compliance
Highly scalable

3. How scalable?
Google manages more than 50000 systems
Zynga scaled from 0 to 10000 servers in 2
months
I am managing tens of machines!

5. Why is Puppet cool?
Centralized, Scalable configuration management for
server farms
Abstracted from underlying OS (to a point)
Configurations can be stored in a version control
system (like Git) for historical change tracking
Automated configuration of individual machines
based on hardware/software configuration
Auditing of configuration of individual machines

6. Where Puppet helps
Bridge the gap between sysadmins and dev teams
Devs: Same configuration as Production
environment
– Need new extension? Update Puppet configurations
Sysadmins: System changes are tracked through
commits, can be reviewed easily
Result: Consistent platforms throughout with
minimal pain

7. Puppet Prod-Dev-Test-QA Example
Production environment
– Dev creates a copy for dev
– Test creates a copy for test
– QA creates a copy for QA
All changes can easily be propagated
throughout all environments

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

12. Auto-Discovered Real-Time Inventory
Data
For every hardware node
Eliminating inefficient, error-prone manual
processes
Full insight into the latest, up-to-date status
of your hardware inventory
© Copyright 2012 EMC Corporation. All rights reserved. 13

13. Dynamic Image Selection
Selects the correct operating system image
Based on auto-discovered, real-time
inventory data
No manual intervention needed

14. 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
© Copyright 2012 EMC Corporation. All rights reserved. 15

15. 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

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

18. Razor installation using Puppet
node razor {
class { 'sudo':
config_file_replace => false,
}
include razor
}

19. Add a broker
rz_broker { 'puppet_broker':
ensure => present,
plugin => 'puppet',
metadata => {
broker_version => '2.7.18',
server => 'puppet.purevirtual.lab',
}
}
© Copyright 2012 EMC Corporation. All rights reserved. 20

20. 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/ubunt
u/ubuntu-cd/12.04.1/ubuntu-12.04.1-server-
amd64.iso",
}
© Copyright 2012 EMC Corporation. All rights reserved. 21

21. 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',
}
© Copyright 2012 EMC Corporation. All rights reserved. 22

22. 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,
}
