> if your AuthN and AuthZ is down, what else would you do ?!! Minor miscommunication… from a write standpoint. Obviously if you can’t auth, you are in trouble. But if the billing needs to happen so you can restore a permission, then you need to hit a card (for example) and then somehow update your authz service. In most cases, it’s not strict availability that’s likely your problem (eg. Full down, no responses) it’s going to be business logic or config issues impacting a small subset of TX. And, honest, if I’m so wrong about this, where is the XA distributed transaction coordinator for Cognito? I’d be shocked if Amazon ever implemented a single-point-of-failure distributed transaction coordinator and exposed that from their services.
