Hello.<br>
Verifying the mappings created for the "Elementary operations on a site" [18] feature against the distributed glance specification [19], I can see a vital feature is missing for "Advanced operations on a site", like creating an image locally, when the parent
control plane is not available. And consequences coming off that, like availability of create snapshots for Nova as well. All that boils down to a) better identifying the underlying requirement/limitations for CRUD operations available for middle edge sites
in the Distributed Control Plane case. And b) the requirement of data replication and conflicts resolving tooling, which comes out, if we assume we want all CRUDs being always available for middle edge sites disregard of the parent edge's control plane state.
So that is the missing and important thing to have socialised and noted for the mappings.<br>

<p class="MsoNormal"><span style="font-size:8.5pt;font-family:"Menlo-Regular",serif">During the second Denver PTG discussions we drafted two MVP architectures what we could build from the current functionality of OpenStack with some slight modifications [2].
These are based on the work of James and his team from Oath. We differentiate between a distributed [3] and a centralized [4] control plane architecture scenarios.<br>
In one of the Berlin Forum sessions we were asked to map the MVP architecture scenarios to the use cases so I made an initial mapping and now we are looking for feedback.<br>
This mapping only means, that the listed use case can be implemented using the MVP architecture scenarios. It should be noted, that none of the MVP architecture scenarios provide solution for edge cloud infrastructure upgrade or centralized management.<br>
Please comment on the wiki or in a reply to this mail in case you have questions or disagree with the initial mapping we put together.<br>
Please let us know if you have any questions.<br>
Here is the use cases and the mapped architecture scenarios:<br>
Mobile service provider 5G/4G virtual RAN deployment and Edge Cloud B2B2X [5]<br>
Both distributed [3] and centralized [4]<br>
Universal customer premise equipment (uCPE) for Enterprise Network Services[6]<br>
Both distributed [3] and centralized [4]<br>
Unmanned Aircraft Systems (Drones) [7]<br>
None - assuming that this Use Case requires a Small Edge instance which can work in case of a network partitioning event<br>
Cloud Storage Gateway - Storage at the Edge [8]<br>
None - assuming that this Use Case requires a Small Edge instance which can work in case of a network partitioning event<br>
Open Caching - stream/store data at the edge [9]<br>
Both distributed [3] and centralized [4]<br>
Smart City as Software-Defined closed-loop system [10]<br>
The use case is not complete enough to figure out<br>
Augmented Reality -- Sony Gaming Network [11]<br>
None - assuming that this Use Case requires a Small Edge instance which can work in case of a network partitioning event<br>
Analytics/control at the edge [12]<br>
The use case is not complete enough to figure out<br>
Manage retail chains - chick-fil-a [13]<br>
The use case is not complete enough to figure out<br>
At this moment chick-fil-a uses a different Kubernetes cluster in every edge location and they manage them using Git [14]<br>
Smart Home [15]<br>
None - assuming that this Use Case requires a Small Edge instance which can work in case of a network partitioning event<br>
Data Collection - Smart cooler/cold chain tracking [16]<br>
None - assuming that this Use Case requires a Small Edge instance which can work in case of a network partitioning event<br>
VPN Gateway Service Delivery [17]<br>
The use case is not complete enough to figure out<br>
