This document discusses DevOps and infrastructure as code. It defines DevOps as a collaborative culture between development and operations teams using unified processes and tools. Treating infrastructure as code allows it to be defined through text files, enabling automation, version control, and consistency. The document recommends automating deployment, containers, logging, monitoring, and communication through various tools and practicing DevOps principles to improve software delivery.

LET'S START WITH
INFRASTRUCTURE AS
CODE

WHAT DO WE DEFINE AS
INFRASTRUCTURE?

• 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

• 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
