One thing to keep in mind for Azure SQL: you are getting a guaranteed SLA [1], business continuity and full point-in-time backups (up to 30 days) [2] for that price. To compare effectively you would need to price out a comparable Always-On cluster, domain controllers, SAN storage (for replication), and backup solution + storage.

I highlight a similar pricing breakdown with their IoT / MQTT service and their price inanities as well. As far as I can tell, this insane pricing is for the idea of "Can't go wrong with purchasing Microsoft Services".... when in actuality, you can go very much wrong.
