Hi, on the quiz for Chapter 3, on one of the explanations of the answers it says this: "It can be a set of datacenters, but often availability zones are within the same datacenter too." I don’t fully understand the 2nd part of that sentence. Is it saying that there can be more than 1 availability zone inside on datacenter?
AZs are individual physical locations within a region. Each AZ is made up of one or more datacenters that have independent power, cooling, and networking. I edited the explanation to help.
