This does worry me. If there is a shortage of resources suddenly or a DC fire that takes out a region, then what? We have contingency against this via our own infrastructure but I worry about organisations who don't have any.

> Amazon EC2 is hosted in multiple locations world-wide. These locations are composed of regions and Availability Zones. Each region is a separate geographic area. Each region has multiple, isolated locations known as Availability Zones. Amazon EC2 provides you the ability to place resources, such as instances, and data in multiple locations. Resources aren't replicated across regions unless you do so specifically.

One region isn't going to be effected by fire. And AWS have dozens of regions. They're even managed as separate units by separate people. You'll notice there's never been a large, multi-region outage of AWS.

  Yet. Some of the traditional apps we host are vulnerable hypervisor failure be that rack, DC or region.

    Hardware always fails. That's why AWS has so many availability zones, regions and services that let you take easy advantage of HA across them.

>This does worry me. If there is a shortage of resources suddenly or a DC fire that takes out a region, then what? Then some businesses will be out for a few hours / days. No big deal. From WWII to 9/11 to Katrina (and whatever regional stuff we have), we have been through much worse than that in modern history.
