Depending on what exactly you mean with multiple datacenters, make sure you take a look at the pictures of their DC sites - the DCs in one location may be right next to eachother. Like having your servers in SBG2 and backups in SBG1.
You would need to use multiple locations, not just datacenters, for durability. The network performance between locations just isn't as good as between datacenters in the same location.

- sterwill 5y agoWith AWS, the "datacenter" isn't a concept users have to worry about (or can even discover or manage). Each AZ comprises many datacenters, each region comprises many AZs, and AWS makes it easy to deploy most services across multiple AZs in a region. If one AWS datacenter goes down (and this happens occasionally), typically only one AZ in the region is affected.
