Now, the cloud offers many features that provide fault tolerance, and we'll cover some of those throughout this course. A fault usually refers to something that causes a problem on a smaller scale. But there's another kind of problem that can impact availability, and that's a disaster. A disaster is a large scale event, and it's more impactful than a fault. A…
