What Amazon Web Services is
S3 defines the interface, the semantics and the edge cases every other provider on this page implements against, and it remains the most complete: storage classes, Object Lock, replication, Access Points, event notifications, and IAM condition keys nobody else matches. It is also the reason this comparison exists, at USD 0.09 per gigabyte, egress on a read-heavy workload costs more than everything else combined.
