There are differences in redundancy and isolation that could impact your resiliency strategy. An AWS zone can include multiple data centers that are isolated from other DCs in the same zone. A region is then a collection of those zones, and each zone in a region could be as much as 60 miles away from another. [0] A cursory reading of the GCP docs indicates that a GCP region is more equivalent to an AWS zone, but that may be a misunderstanding based on the more abstract language used. [1] Azure also seems to treat a region like AWS treats a zone, but they also have a concept of paired regions for more redundancy [2]. I can't seem to find details on the isolation guarantees for their DCs / Zones / Regions / Pairs though.
