We have a local mysql server(not on public domain) and want that server replicated to a google cloud sql instance that we have. My question is that: 1. is this possible? 2. our local server is accessible on the local network only. no public IP, etc. Although the server has internet. Im not sure how replication works, is this a one way traffic from master to slave?
if this is the case, then this might be possible even if the local mysql server is not accessible on the public domain since it only need to connect to the slave up on the cloud.
hope this makes sense
