Hi Lusheng, Which ONAP Module is responsible for floating IP allocation and pooling? Whether it uses Network Controller to interact with underlying SDN layer for connectivity across multiple data centers (read cloud domains).

To second to what Dan said, DCAE?s ?production grade? design is multi-region. It is designed as a multi-tiered multi-region system. Which is natural because functioning as the sensory part of ONAP, in many situations you would want DCAE?s collectors and some analytics to be as close to the VNFs to be monitored as possible. This is also why DCAE Controller spins up additional VMs and other resources of its own in the demos, ? the same pattern is used for deploying and scaling DCAE edge sites in other regions. Regarding using the immutable container pattern for multi OS, I believe most of the ONAP parts are already following this pattern. The rest are marching towards that goal too. For DCAE, the current hurdle is mostly constrained by third party software support (for example CDAP) in containerization and OS. I also want to point out that ONAP is not a traditional cloud application. Compared to those, ONAP probably has more complex inter-dependencies and inter-connectivity between its components, as well as interactions with the underlying networking functions that the cloud infrastructure provides. Which could be configured differently by different providers of the same cloud technology. One example is how the floating IPs are allocated and pooled.

Multiregion support is in onap, just not configured that way for the demo and heat templates we put out ? we used many regions internally at att before opensourcing after all. To add it you have to configure mso to know about all your regions and add some kind of homing rules.

Hey there, I?m pretty new about ONAP but maybe my two cents on this topic can be useful. From OpenStack perspective the only requirement for any image to provision something is to have previously installed cloud-init[1] service (AFAIK, that?s the only difference for Ubuntu Cloud images[2]), but personally I?ll recommend to use an Immutable Server pattern[3](something like docker images or vagrant boxes). Definitely I like the idea of certify and publish which OpenStack Release is supported and even better if this could be cloud agnostic. Lastly, did you consider multi region support?

Good morning all, I would like to start a new thread in order to understand if there is a need to certify ONAP on multiple OS/Openstacks. OS Currently ONAP is running on Ubuntu 14.04 (target to move to Ubuntu 16.04). Open-O is running on CentOS but I understand from Helen Yunxia (Huawei) that it should not be an issue to run it on Ubuntu. Redhat was not considered from a certification perspective due to license cost.
