Well, it does this by using one of several different redundancy options, and the first one is called Locally-Redundant Storage, or LRS. LRS is the least expensive redundancy option, but it's also the least durable. So in LRS, Microsoft creates three copies of your data in the same data center. Now remember, a data center is a specific building at an Azure region.
