> As for AZ outages... in practice, a cross-AZ system is often just as vulnerable to problems from the outage of a particular AZ, especially if any autoscaling is involved. If a system is not resilient to an outage of a particular AZ, by definition I would not call it a 'cross-AZ system'. Maybe what you have in mind is systems that in practice _think_ they are cross-AZ resilient but are actually not when you look closer? |
