All, Currently, under the environment of cloudstack with multiple regions, each region has its own management server running with a separate database. So if we want to support multiple regions and provide one point of entry for a customer, we need to duplicate domain/account/user information of that customer to all of the databases of regions the customer accesses, which will cause data discrepancies when users update those data independently in each management server.
So I'd like to provide a way to sync up the data using the messaging system introduced in 4.1.0. Using the events from each management server, updates from each region can be propagated to the rest regions and they can be executed accordingly. I hope you guys have a chance to think about this and give some feedbacks if interested. Thanks in advance. Alex Ough
