AWS Glue - Fully managed data catalog and ETL service

I'm surprised that there aren't more comments on this, because it seems like it could be enormously useful. My first thoughts are that it could simplify synchronizing data between environments, or coordinating backups where a system has data in both S3 and RDS or RedShift.

Is it just me or does this look like AWS Data Pipeline with an actually feature-complete and usable user interface?

I wonder how Segment, Fivetran, Stitch and all the other ETL vendors feel about this. I have a feeling that the ecosystem will flock towards Glue and leave everybody else in the dust...
