CloudCamp. Julian Fischer Anynines - migrating a cloud foundry from vm ware to open-stack
- 1. Migrating a running Cloud Foundry from VMWare to OpenStack
- 2. • What is Cloud Foundry? • IaaS and PaaS • VMware vs. OpenStack • The migration • Conclusion
- 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)
- 7. • Building against infrastructure requires ops knowledge • Building against a PaaS doesn’t
- 8. It’s all about the Apps!
- 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!
