Datacenters vs Availability Zones
A correction to the article: It compares the count of AWS AZs with competitors datacenters.
AWS approach is that a Region is comprised of a set of isolated Availability Zones with low latency links between them, while each AZ is comprised of one or more datacenters.
Based on this, the 53 AZs number probably correspond to way more than just 53 datacentes, while those information is not publicly available.
