12-Factor App  Codebase : One codebase tracked in version control  Dependencies : Explicitly declare and isolate dependencies  Configuration : All configuration is stored in the environment  Backing Services : Treat all backing services as attached services  Build, Release, Run : Strictly separate build and run stages  Processes : Execute the application as one or more stateless processes  Port Binding : Export services via port binding  Concurrency : Scale out via the process model  Disposability : Maximize robustness with fast start-up and graceful shutdown  Dev/Prod Parity : Keep development, staging, and production as similar as possible  Logs : Treat logs as event streams  Admin Processes : Run admin/management tasks as one-off processes 21 intel.com/cloudforall

WordPress as a 12-Factor App  Codebase : One codebase tracked in version control  Dependencies : Composer and plug-ins listed in composer.json  Configuration : Configuration needs consideration! What goes to the env and how?  Backing Services : DBs, Queues, LB, SMTP, New Relic, API-services  Build, Release, Run : Excellent stage to apply automation tools  Processes : Stateless Processes means considering Sessions & Uploaded Files  Port Binding : Port binding will require nginx+PHP-FPM, and some config work  Concurrency : Consideration needed to avoid long-running PHP- FHM “daemon”  Disposability : Mostly handled by PHP-FHM  Dev/Prod Parity : Automate with VirtualBox/Vagrant & Puppet/Chef/Ansible  Logs : Log files versus stdout … not quite  Admin Processes : Even one-off processes are scripts and under version control 22 intel.com/cloudforall
