In this session, you will learn how Amazon.com migrated 50bp from an Oracle data warehouse to a data lake and optimized analytics platform in the cloud. We discuss the data value chain that decentralizes and democratizes the access and use of data for the Amazon.com teams. We show how the new system allows different teams to publish and store their data. How teams that consume data can discover, subscribe, receive and use it. We share the lessons Amazon.com has learned in implementing this large-scale transformation and change management effort. This session shows you that even large-scale cloud migrations are possible and shares feedback from one of the world's largest e-commerce companies.
