Amazon’s consumer business has turned off its final Oracle database, after migrating 75 petabytes of internal data stored in nearly 7,500 Oracle databases to multiple AWS database services including Amazon DynamoDB, Amazon Aurora, Amazon Relational Database Service (RDS), and Amazon Redshift.
The migration project lasted several years and more than 100 teams in Amazon’s Consumer business participated in the migration effort.
This includes well-known customer-facing brands and sites such as Alexa, Amazon Prime, Amazon Prime Video, Amazon Fresh, Kindle, Amazon Music, Audible, Shopbop, Twitch, and Zappos, as well as internal teams such as AdTech, Amazon Fulfillment Technology, Consumer Payments, Customer Returns, Catalog Systems, Deliver Experience, Digital Devices, External Payments, Finance, InfoSec, Marketplace, Ordering, and Retail Systems.
“The migrations were accomplished with little or no downtime, and covered 100% of our proprietary systems,’ said Jeff Barr, Chief Evangelist for AWS.
According to Amazon, it had reduced its database costs by over 60 percent “on top of the heavily discounted rate we negotiated based on our scale.”
Oracle CEO Larry Ellison has been making fun of AWS for years.
