  • ELB codepicnic.com, assets

  • Codepicnic APP Server

    • Rails: codepicnic.com (nginx + passenger + rails)
    • Assets: assets01.codepicnic.com, assets02.codepicnic.com, assets03.codepicnic.com (nginx)

  • S3 Backups

    • Daily Snapshots: A Jenkins Job launch an AMI backup (no reboot) of all production instances
    • Daily Backups: A scheduled job launch a rails task which uses the backup utility to dump the mariadb and redis databases. The utility also send the dumps to S3.

  • Deployment

    Deployment is made through Jenkins (job codepicnic.com) which in turn uses recap/capistrano to deploy the rails application. "ubuntu" is the deployment user, and "codepicnic" is the application user.
