This document discusses migrating an Oracle database to Amazon RDS. It outlines that DBaaS like RDS reduces management costs but also has less flexibility than self-managed EC2 databases. The document then describes a process for migrating an Oracle database to RDS using Oracle Data Pump utilities to export the database, transfer the export file to RDS using DBMS_FILE_TRANSFER, and import the file into a new database on RDS. This process leverages an EC2 instance as a pivot to help mitigate issues with directly uploading large export files to RDS.
