Sure, but AFAIK S3’s multi-region capabilities are quite far behind GCS’s.

S3 offers some multi-region replication facilities, but as far as I’ve seen they all come at the cost of inconsistent reads - which greatly complicates application code. GCS dual-region buckets offer strongly consistent metadata reads across multiple regions, transparently fetch data from the source region where necessary, and offer clear SLAs for replication. I don’t think the S3 offerings are comparable. But maybe I’m wrong - I’d love more competition here!

Entirely different claim.

I claimed that Google is the only major cloud provider with all three of:

- single-zone object storage buckets

- regional object storage buckets

- transparently replicated, dual region object storage buckets

I agree that AWS has two of the three. AFAIK AWS does not have multi-region buckets - the closest they have is canned replication between single-region buckets.

not quite the same, but S3 does have https://aws.amazon.com/s3/features/multi-region-access-point..., which would let you treat multiple buckets in different regions as one single bucket (mostly). But you still do need to set up canned replication.

S3 doesn't have "transparently-replicated dual-region object storage", which was part of the claim.

S3 does have replication, but it is far from transparent and frought with gotchas.

And it certainly doesn't have all of that with a single API.
