I may be mistaken, but I really could’ve sworn that a lot of the really strict SLA guarantees Amazon gives assume you are doing things across availability zones and/or regions. Like they’re saying “we guarantee 99.999% of uptime across regions” sort of thing. Take this with a grain of salt, it’s something I only half remember from a long time ago.
Amazon has so much redundancy built into EC2 that I genuinely thought they’d be able to avoid this.
You should plan for your app to be multi regional if it needs to be up that much.
That’s what I’m saying. I took an amazon class last summer and that seemed to be the base.
I blame the customers being cheap or app teams being dumb not Amazon if apps are still down after a few hours of regional downtime.
Hardware? Yes
Network misconfiguration? Welll…
