Oracle co-founder and CTO Larry Ellison found himself in hot water (again) following a customer-win claim he made on the company’s fiscal third quarter 2020 earnings call with investors.

On the call, Ellison said brokerage firm Depository Trust and Clearing Corporation is moving off of Amazon Web Services and onto Oracle’s public cloud. DTCC, he said, “is migrating their multi-terabyte Amazon AWS Redshift system out of Amazon and into our public cloud using the Oracle Autonomous Database,” he said. “They’re also moving their analytics from Amazon to the Oracle Analytics suite.”

DTCC, however, says Ellison’s claim is not true. “Oracle inaccurately reported during its Q3 earnings call that DTCC was migrating a ‘multi-terabyte data warehouse’ from Amazon Web Services to Oracle’s public cloud service,” a DTCC spokesperson said in an email to SDxCentral. “DTCC uses AWS to support a variety of business functions, and DTCC does not have any plans to move applications from AWS to Oracle.”

The brokerage firm does use several Oracle products, including Oracle Autonomous Database and Oracle Analytics Cloud, which supports its corporate HR and finance functions, the spokesperson continued. “Currently, DTCC’s core clearance and settlement services for the U.S. securities markets are not delivered through any public cloud.”

When asked about the mixed messages, an Oracle spokesperson obfuscated. “Any interpretation of Larry’s comments to imply DTCC’s core clearance and settlement services for the U.S. Securities markets are delivered through any public cloud is inaccurate.” The spokesperson did not address Ellison’s claims about DTCC moving workloads from AWS to Oracle.
