TOPIC DevOps trends What is Test Driven Infrastructure? CMDB’s Your workflow and environment Uses Demo DevOps Trends The lay of the land Where DevOps was, is and will be. TDI? What’s it about? Automation safety nets. Role of CMDB’s ISO20k/ITIL What is vs. What should be Workflow Delivery Opportunities for integration into delivery pipeline Uses More than testing Obvious cases Right cases Wrong cases Demo TDI in action A small canned demo illustrating the tip of the iceberg Agenda What You Can Expect From This Talk
Trends Continued So Many Variables Container wars Docker? Not so fast. What about rkt? Canonical LXD? MS Drawbridge? 1 Good ol’ shell scripts Ansible? Chef? Puppet? Salt? CFEngine? Orchestration tools 2 Heroku? AWS? Google? EngineYard? CloudAfrica? The Cloud 3

Trends Continued So Many Variables Heroku? AWS? Google? EngineYard? CloudAfrica? The cloud 3 No longer about simply on-demand deploy. That doesn’t scale. Mass system (not server) deploy on test pass Continuous Delivery 4 Enterprise lagging behind. Is this a threat, or an opportunity? Still figuring this Devops thing out 5
What Is Test Driven Infrastructure Introducing Serverspec - What It Is Agnostic Open Source Based on RSpec Win or Linux Version 2 just released SOME HIGHLIGHTS ON SERVERSPEC Serverspec tests your servers' actual state by executing commands locally, via SSH, WinRM, Docker API, The true aim of Serverspec is to help refactor infrastructure code.
Serverspec Feature Showcase Super fast to setup. First tests can be ready in less than 5 minutes. BOOTSTRAPPED SETUP Hardware, Software, Packages, Containers, and lots more TONS OF RESOURCE TYPES
Serverspec Feature Showcase Add to your existing Ruby Gemfile. Or, add to any other project. Or, create a dedicated project (Ops) RUNS WHEREVER RUBY DOES Gather facts about the system and verify their state. HOST INVENTORY
Serverspec Feature Showcase Easy to read, browse and discover. Docs also available in Dash. SUPER GREAT DOCS Github search: serverspec & specinfra TONS OF PLUGINS

Workflow And Environment Vision Of A Typical Workflow For TDI Time to figure out what your client wants 1. NEW WORK! Bootstrap your app environment. 2. GET STARTED What will this run on, and how? 3. ARCHITECTURE New requirements 6. CHANGES! Test all environments if possible. 5. INTEGRATE TO CI Reflect the new reality 7. REFACTOR! Get your infra back to green. 8. RETEST Steps 2 - 8 9. REPEAT Write tests that reflect your target arch. 4. GET TESTING!
