Alex Ough commented on CLOUDSTACK-4992:
---------------------------------------
Added a new feature that was requested internally, which is to provide an
option to assign the same uuid when creating the same resources in other
regions.
There is a new global parameter, 'multi.region.resource.uuid.match' whose
default value is false.
If set to true, the uuid of the target resource will be assigned when the same
resource is created in other regions.
If set to false, each region will use different uuids for same resources.
Default value is false.

>
> 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.
