  12. 12. Environment Variables • Zero intervention deployment • Running systems only differ through env vars • Add-ons own their config
  13. 13. OAuth Setup • Create Remote Access Application for App • Set: • SFDC_OAUTH_CLIENT_ID • SFDC_OAUTH_CLIENT_SECRET

  16. 16. Logging • Logplex is Herokus central logging system • Stream of STDOUT from Dynos, load balancer requests, slug compiler • Stream is pipe-able • Accessible via API • Heroku Add-ons can receive logs
  17. 17. Collaborators • Can push changes to an app • Could be a CI build system
  18. 18. • Use the Memcache Add-on for simple session externalization • Many other Heroku Add-ons
  19. 19. Scale == "allocating Dynos a process" Methods: • API • CLI • Eclipse Plugin • Third-Party Auto-Scaling Tools
