AZs don't really help when it's AWS' own services across the entire region that break. Anecdotally, we have had customers accept outages that were out of our control without penalty.

Wild, that wouldn't have flown with datacenter providers having issues for my previous companies. AWS really does have an easier time than old school datacenter providers. I guess the complexity is higher but it's shocking that they can charge so much yet we hold them to a lower standard.

  DCs are pretty static and offer way fewer services than AWS or any other public cloud. I worked for one for some time and whenever we had issues, some people would call and ask if we were going bankrupt. It gave me a feeling they also have way smaller customers that might not understand the underlying stack.

    If all you use in AWS is static EC2 instances you would have to go back a looooong time to find an outage which affected their availability. Even in us-east-1.

      December 22, 2021 was the last partial impact we had in us-east-1 for EC2 instances. They had power issues in USE1-AZ4 that took a while to sort out.

  Outage rates are also wildly different. When you're using dozens of managed services and have a few prod-impacting outages with any reasonable (cross-AZ) design, customers are less sensitive then when they are dependent on dozens of products that hav independent failure modes with potentially cascading impact.

AZs also don't help with natural disasters at all. I believe AWS is the only one doing geographically distributed AZs, for the others it just means different connections and placed somewhere else in the building. edit: turns out AWS is the one with geo distribution, not Azure

  Aws azs are also distributed geographically within a region w separate power and network lines. From the docs “ Availability Zones are distinct locations within an AWS Region that are engineered to be isolated from failures in other Availability Zones.”

    Ah, you are probably right. I was thinking of the incident a few weeks back where the fire suppression took out multiple AZs, but that was actually GCP.
