Transcript

  • 1. Migrating a running Cloud Foundry from VMWare to OpenStack
  • 2. • What is Cloud Foundry? • IaaS and PaaS • VMware vs. OpenStack • The migration • Conclusion
  • 3. Cloud Foundry
  • 4. • = application platform = PaaS software • Open source software (apache 2)
  • 5. API request Router Router Droplet request DEA DEA DEA DEA DEA Router Cloud Controller Droplet change notifications Request droplet start/stop Droplet heartbeat & exit messages Router Health Manager Get desired states Droplet / Service metadata Cloud Controller Database Consume a service Service Services Services (e.g. MySQL) Services (e.g. MySQL) (e.g. MySQL) (e.g. MySQL)
  • 6. IaaS and PaaS
  • 7. • Building against infrastructure requires ops knowledge • Building against a PaaS doesn’t
  • 8. It’s all about the Apps!
  • 9. VMware vs. OpenStack
  • 10. • VMware is a fine piece of technology • If you have invested into it, no immediate need to move away from it. • OpenStack is an upcoming candidate and might become the industry standard for infrastructure • Open source and enterprise versions available (Piston, Canonical, HP, …)
  • 11. Our requirements
  • 12. • We already had OpenStack knowledge • For a public PaaS buying costs is everything —> Saving license costs was key! • Moving from a hosted VMWare to a selfhosted Openstack…
  • 13. … doubled monthly costs quadrupled RAM and CPU cores!
  • 14. The Migration
  • 15. > 1 week to prepare
  • 16. < 1 hour to execute
  • 17. < 30 min downtime
  • 18. • Setup the OpenStack environment • Deploy Cloud Foundry on OpenStack • Migrate configuration, data and apps • Switch DNS entries
  • 19. • Official migration announcement in the anynines blog
 http://rh.gd/a9vmw2sos • A blog post about technical details will follow on blog.cloudfoundry.com
  • 20. Conclusion
  • 21. Building against a PaaS protects investments made into software development.
  • 22. An infrastructure must be present. ! Which one doesn’t matter.
  • 23. Thank you!
