The tutorial addresses three-member replica sets and five-member replica sets. This is to help guard against data loss in the case of a hardware failure. MongoDB Atlas customers can enable cross-region replication for multi-region fault tolerance and fast, responsive reads. The three data centers we have in use have the following latencies: A <> B: 5 ms A <> C: 25 ms B <> C: 25 ms The database is used with real-time applications (user frontend…) and therefore we cannot have any long latencies with reads and writes. You need to explain a little bit more, what you are looking for.
