Subject Re: [DISCUSS] Domain/Account/User Sync Up Among Multiple Regions

All,

While I'm waiting for the permissions, I'd like to bring up a discussion on
the overall architecture to support this feature.

There can be 2 different approaches as below.
1. master - slave architecture : the manual changes are allowed only in one
master management server, and those in other servers are either prohibited
or discarded.
2. multiple source architecture : all management servers allow manual
changes and any change in any server will be propagated to the rest of
servers.

I'm not sure if we can impose the restriction of #1.
If not, #2 is a little more complicated, but the only issue is to
distinguish the events from either manual jobs or triggered automatic
processing, which I'm currently working on.

Your comments/recommendations will be very appreciated.
Thanks
Alex Ough
