9. "In the Ocata cycle, Cells v2 has now moved to the required deployment
model for model," - Johnathan Bryce, Executive Director of the OpenStack
Foundation
"By default, an Ocata deployment now needs to configure at least one new
Cell V2," the release notes state.
Nova in change

10. At a basic level, Nova cells creates a hierarchy of Nova installs, each with its
own database, message queue backend, scheduler, and compute nodes.
So… What is Cells?

11. So… What is Cells?

12. - Require create cell when deploy
nova-manage cell_v2 create_cell --name cell1
nova-manage cell_v2 discover_hosts
Nova in change

13. - We need at least three databases for Nova
Nova in change

14. Nova in change
- Nova-placement-api used to track resource provider inventories and usage
- Compute node
- Share storage pool
- External IP pool
- DPDK, SR-IOV
- In Ocata Release, nova-placement-api was separated from nova-api code
and running service under Apache
- Compute service need placement credentials at placement section
- In the future, maybe it will be separated and become a new project with
name: Quota as a Service.

15. Glance?
- New method to share image: community
- Users can now create “community” images, making them available for
everyone else to use.

16. Glance
User can boot with this image new

17. What’s about Cinder?
- Before, cinder-volume service only accepts Active/Passive High Availability
configurations
- Now, Active/Active HA Cinder can run in clustered mode (not verified)

18. Neutron?
- Support for Routed Provider Networks in Neutron
- Nova scheduler uses this inventory as a hint to place instances based on
IPv4 address availability in routed network segments.

19. Others but not verified
- Magnum now supports DC/OS as a cluster type as well as Kubernetes on
Suse
- Zaqar can now use Swift as a storage option, providing built-in replication
capabilities.
