Personally, I prefer the terms leader/follower but primary/replica currently seems to be more common in the industry. At some point, the word slave will be used, but because it is the keyword embedded on the server to represent a replica.

The steps given will be in the context of a VM running a one-click install of …

In this article we will explore one approach for deploying ProxySQL behind a load balancer in Google Cloud.
