LET'S START WITH
INFRASTRUCTURE AS
CODE
- 19. 19© Copyright 2015 EMC Corporation. All rights reserved.
WHAT DO WE DEFINE AS
INFRASTRUCTURE?
- 23. 23© Copyright 2015 EMC Corporation. All rights reserved.
• Deploy, monitor and connect together all the pieces
needed to run services for the organization
• Processes and tools for faster end-to-end delivery of
quality services
• Automation comes built-in
WHY DEFINE INFRASTRUCTURE AS CODE?
- 24. 24© Copyright 2015 EMC Corporation. All rights reserved.
• Desired state specified in text files
• Autonomic (self-corrects to desired state)
• State should be known through monitoring
• Remove snowflake servers
HOW DO WE DO THIS?
- 25. 25© Copyright 2015 EMC Corporation. All rights reserved.
• Easy to read and edit
• Shareable
• Can use standard version control like Git or SVN
• Becomes executable documentation
WHY STORE THEM IN TEXT FILES?
- 26. 26© Copyright 2015 EMC Corporation. All rights reserved.
node 'www2' {
class { 'apache': } # use apache module
apache::vhost { 'awesomewebsite.com': # define vhost
port => '80',
docroot => '/var/www/html'
}
}
SIMPLE EXAMPLE

user { root:
ensure => present,
password => '$ecretP@ssw0rd',
}

• Deploying, provisioning and scaling automatically is
virtually impossible if every server is unique
• Adds friction between the requestor and the deployer
• Mistakes happen
• We're all human

WHAT CAN HAPPEN IF YOU
DON'T TREAT
INFRASTRUCTURE AS CODE?

UP TO 60% OF FAILURES ARE
CAUSED BY HUMAN ERROR, NOT
