Ah, spoken with the confidence of a freshly minted qualified worker :). Anything you don’t test is a wish, not a production system. You either know that your systems work end to end because you tested periodically, or you pray they will.

How do you know the automatic failover works? How do you know the standby system works?

I’ve seen many a “qualified workers” getting sent packing because they never fully tested the prod system because they just knew everything will work, and never tested the backup systems because qualified workers do the job right the first time, no need for backup.
