The cause of – and the solution to – all of life's problems.

A Brief History of Computing

Punch Cards

Personal Computers

Users . . . The Wall . . . Operations

Puppet: What is a DevOps Engineer?

• Coding/Scripting
• Strong grasp of automation tools
• Process re-engineering
• A focus on business outcomes
• Communication & Collaboration

Questions?

Puppet & Chef

• Configuration Management
• Portable
• Repeatable

Puppet

• http://puppetlabs.com/

• Modules @ Puppet Forge

            
              package { "gtypist":
                ensure   => installed,
                provider => homebrew,
              }
              package { "redis":
                ensure   => installed,
                provider => homebrew,
              }
            
          

Chef

              end

              package "redis" do
                action :install
              end
            
          

Vagrant

http://www.vagrantup.com/

            
              Vagrant.configure do |config|
                config.vm.provision "puppet" do |puppet|
                  puppet.manifests_path = "my_manifests"
                  puppet.manifest_file = "default.pp"
                end
              end
            
          

You build it; you run it.

Deliver working code AND the environment it runs in.

T.D.D.

Dev and Test are no longer separable

What we need from Ops

• One button environment
• One button deploy

First Steps:

• Automate something simple
  • White space
  • Dev Log rotation
  • .Dotfiles
• Automate something not-so-simple
  • Development machine configuration
  • Production configuration
