Different instances, clusters and regions

Answer this question
Resolved
kim xin2022-12-28

Can different instances in the same cluster be in different regions? I mean if my company is in USA for example, and my clients are in Italy or somewhere in the Europe, I wish my instances can be differently located.

    Hi, this is a very good question. Technically a cluster can be deployed to different regions as long as the network is connected. If we want all instances to be read-write, one thing to figure out is the synchronization strategy of all instances when inserting, deleting or modifying data. Because the latency of synchronization can be very high if instances are located in different regions, and the strategy of synchronization is definitely different from the conventional ones. A work-around is to either set the instance, the one far from the rest, with the role of read-only, or revoke the permission of writing to this instance from all the users, so this 'expat' instance will not trigger frequent synchronization while it still can be read by the client who are closer to it.
