    • Start with a personal story My goal was to: Deploy apps Maintain infraMonday, January 28, 13
    • Start with a personal story That’s me 3 years ago.Monday, January 28, 13
    • Confused Start with a Chef What should I do? Puppet personal What should I choose? story Control I have to maintain Tier That’s me 3 years CFEngine infrastructure ago. But I also have to deploy my apps ... Are these the ??? same?Monday, January 28, 13
    • Monday, January 28, 13
    • Aha !!!Monday, January 28, 13
    • Aha !!! I need a tool that:Monday, January 28, 13
    • Aha !!! I need a tool that: Maintains InfrastructureMonday, January 28, 13
    • Aha !!! I need a tool that: Maintains Infrastructure AND Deploy my apps!Monday, January 28, 13
    • Maintain Infrastructure AND Deploy my apps ???Monday, January 28, 13
    • I didn’t find it Maintain Infrastructure AND Deploy my apps ???Monday, January 28, 13
    • ??? Maintain Infrastructure AND Deploy my apps ???Monday, January 28, 13
    • But Why ??? ??? Maintain Infrastructure AND Deploy my apps ???Monday, January 28, 13
    • They are not the same! Infrastructure ≠ App DeploymentMonday, January 28, 13
    • Oh... They are not the same! Infrastructure ≠ App DeploymentMonday, January 28, 13
    • Why are they different? And what do they have in common?Monday, January 28, 13
    • And what did I end up using?Monday, January 28, 13
    • What did I use? Case 1: Chef gluMonday, January 28, 13
    • What does chef do? Installs infrastructure java databases etc... Installs Glu server and agentsMonday, January 28, 13
    • What does glu do? Deploy our apps Tomcat based appsMonday, January 28, 13
    • What did I use? Case 2: Chef FabricMonday, January 28, 13
    • What does chef do? Provision servers Install Java, Tomcat Install DBs Set up users, keys logstash nagios, etc...Monday, January 28, 13
    • What does Fabric do? Deploys apps Tomcat based or jetty Notifications testsMonday, January 28, 13
    • Isn’t it easier to use just one tool? Yes!Monday, January 28, 13
    • So why am I using two tools? Because they are differentMonday, January 28, 13
    • Let’s take a look at the tools now Infrastructure ≠ App Deployment !!!Monday, January 28, 13
    • Chef Recipes, Resources, Convergence.Monday, January 28, 13
    • Puppet Define Desired State Enforce MonitorMonday, January 28, 13
    • CFEngine Desired State Self Healing MonitorMonday, January 28, 13
    • Control Tier Command DispatcherMonday, January 28, 13
    • glu Deployment Automation and MonitoringMonday, January 28, 13
    • fabric Deployment and administrationMonday, January 28, 13
    • Capistrano Remote server automationMonday, January 28, 13
    • Hybrid? So - Chef, Puppet, CFEngine maintain infra But - can they also deploy applications? They could... But - it’s awkward ☹ Example: Use shef for ad-hoc tasks.Monday, January 28, 13
    • Hybrid? So - glu, fab, cap, CTier can deploy But - can they also maintain infra? They could... But - it’s awkward ☹ Example: Use fabric to deploy mysql.Monday, January 28, 13
    • Why awkward? Because Infrastructure ≠ Deployment automationMonday, January 28, 13
    • How is it different? Let’s see...Monday, January 28, 13
