AWS's availability zones are unlike Google Clouds AZs, as they are physically meaningfully distant.
A geological or technical event near one AWS AZ is highly unlikely to also affect the others of that region, unless the event is regional (heh) in scale. For Google Cloud, the AZs are effectively co-located buildings (or at least, Eemshaven has 3 GC AZ DCs at < 1km distance from each other), making even local disruptions reasonably likely to impact availability for the whole region.
- nrmitchi 5y agoYes, that being said, I would expect those same precautions to be taken in all regions, and thus not give a meaningful difference per region, between regions (if that makes sense).
- kbenson 5y agoDifferent regions have different types of worries. Distance and precautions required to deal with redundancy for an earthquake may not be the same as required for a tornado, or hurricane, or flood, etc. In some cases, I imagine elsewhere in the same large city may suffice. In others, maybe it requires 50-100 miles.

- jitl 5y agous-east-1 is a very special region. All of Amazon.com runs/ran there for a long time. And a lot of global features of AWS itself run there too.
- chrisandchris 5y agoIsn‘t it interesting how less one knows usually about exact specs of the Cloud?
- chickenbane 5y agoYou're correct that some Google Cloud zones are in the same physical building. However, the separate zones are designed with independent power, cooling, and networking. So, failure events usually affect only a single zone.
