Hi We currently running our moinmoin wiki on an Amazon instance in North Virginia. We have people in China who are trying to access it and are reporting very poor access performance. I'm thinking that one way of solving the problem would be to set up a second server in a location nearer to China, e.g. Tokyo or Singapore.
Off the top of my head, it would seem to be relatively straightforward to set up the Asia instance as read-only and then use rsync to replicate changes from the US instance to Asia. I could then use Amazon's geo technology to redirect users to the "nearest" server. However, there are some problems/challenges with this approach. 1. If a user gets directed to the Asia server, what happens if they want to edit? I could potentially redirect the Edit links to the US server by using an explicit URL that bypasses the Amazon cleverness, but then the user could end up permanently on that server. 2. Ideally, both servers would be writeable and I'd be syncing in both directions but there is the risk of a collision then with two different people editing the same page at the same time. It would be a small risk, but the risk is there. Has anyone tried to tackle this sort of requirement before? Or anyone got any suggestions or recommendations on how to tackle it? Thanks.
