Question:I understand that it's become possible to replicate data overseas. As someone with multiple data centers in the U.S. and Europe, I'm wondering how reliable such a system would be. Can you offer any ideas on what to expect in terms of reliability and availability from an overseas replication solution?
Evan Marcus' response:
It is certainly possible to replicate data overseas with one or two very important caveats. As I've discussed before, there are two (more, actually but we'll just discuss two here) kinds of replication, synchronous and asynchronous.
