Auto-deployment script customanization for successful local deployment
Great support form ONF
help for Physical cord platform deployment and work shop in Aug. 2017
remote support and guidance for deployment and problem debugging

19. Suggestions on CORD Platform evolution
Further improve stability and efficiency of building and deployment
easy update cord platform without re-deploying from scratch
More stable process for PXE booted computer nodes
Multiple options for computer node installation: MaaS booted vs. others ways for computer node installation
Cooperation with other Open Source Community and Standard Organization
ONAP 、OPNFV、OCP、OVS….
MEF、BBF、ONF…
Work together with all partner to build the ecosystem

20. Suggestions on CORD Platform evolution
The mechanism is different between operator and the Open Source Community
Development: per-plan the development plan、slow speed of development
Operation: service change at any time 、quickly deployment and adjustment
The lab testing vs deployment in real network
Distribute architecture of head nodes for practical deployment: De-couple among the cord platform infrastructure services

Openstack cluster
ONOS cluster
