How do I know how much of my cloud infrastructure is redundant?

By  

Most cloud providers offer to automatically protect your data by running independent and geographically distinct data centers, so that your infrastructure will remain running even if one of their data centers fails. But that isn't the same as knowing where your data is actually physically located and whether or not you can specify which data center you want to be located. It doesn't hurt to ask before you start using the service. Amazon, for example, has several distinct "zones" in North America, Asia and Europe where its servers are located. A user can specify the location of his virtual servers and design an environment to be protected in case of any failures. A more complete discussion of the various security decisions involved in using Amazon's Web Services can be found here.

Amazon has four different geographically distinct regional data centers that are used to serve up its cloud services.
