Executive Summary

On October 15, 2019, Amazon announced via a blog post that it had finished migrating its internal consumer databases from Oracle database software to Amazon Web Services (AWS).

• The teams migrated 75 petabytes (75 x 10¹⁵ bytes) of internal data stored in nearly 7,500 Oracle databases to multiple AWS database services.
• Migrated brands include Alexa, Amazon Prime, Amazon Prime Video, Amazon Fresh, Kindle, Amazon Music, Audible, Shopbop, Twitch and Zappos.
• Benefits to Amazon include cost reduction, performance improvements and lower administrative overhead.
• The move also gives AWS more control over its own data, moves its services out of the hands of a competitor and also signals AWS’ increasing competition with Oracle in the database space.
