Re: AWS S3 outage and proper architecture
Thanks for the detailed comments. Yes - if you automate a poorly defined process, you are going to crash and burn faster. And there is no 'stress testing' that either cloud providers and enterprises are voluntarily embracing to expose any holes and fix them. But first step is to know what you don't know or haven't acknowledge - the scope, privileges and putting a governance around that

Re: AWS S3 outage and proper architecture
These are the large-scale issues that can afflict cloud systems. I'm sure Amazon and Microsoft are learning from the mistatkes made. Let's keep in mind that this is all still really new, and everyone is learning as we all go along.

AWS S3 outage and proper architecture
Northern Virginia is the cheapest AWS region and many services including AWS own dashboard do not follow AWS high availability architecture recommendations and use only one region, the cheapest one, even for valuable services and data. 

Backup and disaster recovery is also an issue and using multiple public cloud providers for most valuable services and data makes sense. Especially in case of natural disasters public cloud providers should ensure that rest of the regions can operate without disruption and AWS outage proved that AWS can deliver on that expectation. Funny part of the story was that some AWS own applications were impacted due to single region architecture as well as may other popular applications relying on only one region availability.

With automation scripts that take manual input there will always be possibility for humans to cause disaster even with well defined scope, privileges and governance model but the point is that with proper architecture in case of both human caused and natural disasters public cloud provides real benefits and can cope with them - especially by using public multi cloud for high availability architecture.
