"To me, this outage is the most worrisome of all AWS service disruptions that I know about. In a nutshell:
AWS effectively lost its control plane for entire region as a result of a failure within a single AZ.
This was not supposed to be possible."
I find it funny how we have this assumption that if we don't architect across multiple AZs or regions we shouldn't be surprised when our service goes down because of an AWS failure, but that if we do, we're "pretty safe" -- and then Amazon itself experiences failure spanning AZs from a single-AZ failure.
- Dylan16807 14y agoYes, the outages that happen don't worry me much, things will happen. But they have inter-AZ issues in the management system disturbingly often.
- Zombieball 14y agoCorrect me if I am wrong, but I believe if your application was designed to operate across multiple 'regions' your app would have indeed been safe from this failure.
- mokeefe 14y agoSure, but then your app needs to communicate across the Internet if you share data across regions. This can be expensive and/or slow and/or unreliable. http://aws.amazon.com/ec2/faqs/#how_will_I_be_charged_for_data_transfer http://aws.amazon.com/ec2/faqs/#how_will_I_be_charged_for_da...
