One aspect I would mention is the naming in Amazon S3. If I create an S3 bucket with a specific name, such as 'Roberto bucket,' I cannot create it in another account with the same name.

There is a limitation with the data upload size, such as the five terabytes restriction. I would like to see an increase in the data upload limit, similar to DynamoDB, where there is no data limit.

Sometimes it's difficult to set it up, such as when naming your bucket. The naming conventions require unique global names, which can be cumbersome.
