A single master db isn't sufficient for any production app; you should have no single points of failure and that includes having at a minimum 2 db's. Clustering

A single master db isn't sufficient for any production app; you should have no single points of failure and that includes having at a minimum 2 db's. Clustering isn't a what if scenario, it's a must have for any serious business, single points of failure are not acceptable.
- manigandham 8y ago100% uptime is impossible and the vast majority of companies do not need anywhere near the 99.99% they claim is necessary, nor can they actually pay for it. A 30-second outage to switch to a replica is perfectly fine for production.
- zorga 8y agoIf you have a replica, you have two db's already as I've suggested. And no one said anything about uptime; the point was single point of failure, not uptime. When I said single master, I just meant a single db as opposed to a master/slave setup.
