AWS states that bucket names must be unique at the global level.
At the same time buckets are defined at region level.
Does that mean that I can have two buckets with the same name in different regions?
Example : is it possible to create randomn_name.s3-us-east-1.amazonaws.com and randomn_name.s3-us-east-2.amazonaws.com under east-1 and east-2 regions?

no, you can’t. what you described is the S3 DNS generated for the bucket, and not the bucket name.
the S3 DNS pattern is:
<bucket-name>.<aws-region>.amazonaws.comThe first part,
<bucket-name>, must be unique globally.You can append the region name in the bucket name, but your S3 DNS will have the region two times.
For example,
S3 bucket name:
random_name_us-east-1S3 DNS:
random_name_us-east-1.us-east-1.amazonaws.comWhile data in Amazon S3 buckets is stored in a Region, the Bucket Name is globally unique.
Therefore, you cannot have the same bucket name in different regions.
