Zone-redundant storage (ZRS) This option replicates the data in three different availability zones in the same region. Each zone is independent from the others at the hardware and base service levels, like power, network, and so forth.

Like LRS, the write process is synchronous for the three availability zones.

Geo-redundant storage (GRS) With this option, LRS is expanded with another LRS but placed in another geographical region. The primary LRS is written synchronously, and then the data is sent asynchronously to the second LRS, which repeats the synchronous process in the second region before confirming the second phase as committed.
