- 3. 3 Update from PHL • API to query network IP usage • Neutron spec: https://review.openstack.org/180803 Please comment! • Patches: https://github.com/godaddy/openstack-neutron/tree/network-ip-usage https://github.com/godaddy/openstack- neutron/commit/fcf325f9f9f7a9f87ba6bc1c53f9212d0e2decee Network usage API extension

- 7. 7 Improvement Ideas • Run glance, neutron-dhcp-agent locally on all compute nodes • One leader to cache from Ceph? • Centralized nova-metadata-api • All servers in rack now the same type • Simplifies provisioning & builds

Notes de l'éditeur
- Explain where and how we run metadata service (don’t use neutron metadata proxy.)
- https://etherpad.openstack.org/p/PHL-ops-arch-show-tell disparate public and private cloud in each geographical region US west regions in place today US east coast coming in Q2 EU/AP later this year Mostly used for dev/test, but starting to on board production applications and VPS-like hosting Saved >$2.5M in 2014 by using OpenStack We use Anvil to build packages (Kris is a core), and Puppet with stackforge modules for config management Keystone, Nova, Neutron, Glance core services. Also Heat and Ceilometer, but those aren’t really used. Use HAProxy to SSL terminate a lot of things Glance runs on pod servers (close to compute) to optimize network transfer Keystone with AD backend for users/groups identity No Swift or Ceph yet VMs get a single root volume on local disk, and config drive Using Nova cells No live migration
