16
+:problem: Individual glance nodes are fully un-aware that there might be
17
+          other nodes operating in the same space. This lack of communication
18
+          between the nodes causes issues separating workers and operating in
19
+          different locations.
20
+
21
+:solution: We have message queues already utilized in notifications and other
22
+           projects. Lets expand that for communications between different
23
+           glance-api nodes to gain better operational efficiency.

30
+:alternatives: We could use something else than the message queues but
31
+               effectively that would end up recreating something like registry
32
+               but just as a message broker.
33
+
34
+:timeline: Possible initial functionality in Rocky, more use cases covered S
35
+           and beyond. This can be expanded fairly easily so we can proceed as
36
+           time permits.
