amazon's data warehousing service is called redshift
Amazon Redshift Amazon Redshift is an Internet hosting service and data warehouse product announced in November 2012 which forms part of the larger cloud-computing platform Amazon Web Services. It is built on top of technology from the massive parallel processing (MPP) data-warehouse company ParAccel (later acquired by Actian),[1] to handle large scale data sets and database migrations.[2] Redshift differs from Amazon's other hosted database offering, Amazon RDS, in its ability to handle analytics workloads on big data data sets stored by a column-oriented DBMS principle.
