I've worked at one of those companies that have the live/standby model in place.
The problem is, how to switch load from live to stand-by in case of problem often requires manual intervention and a procedure.
The procedure must be tested from time to time, and adjusted according to changes.
Oh and the live and standby environments must be kept in sync...

- kccoder 4y agoMy go to setup if I need more uptime that a single server running in google cloud with live migration grants, is a three node galera cluster, with an A-record pointing to each node, which also runs the application in addition to the database. You can do rolling updates without any downtime, and I've even had setups like this go years without downtime. It isn't perfect but it works very well and obviates having to worry about things like stand-by switchover.
