There's 'no way' customers would migrate from Oracle to Amazon database software, Ellison says

Oracle is still swinging in the battle for the database market though the race to own the cloud appears to belong to Amazon Web Services. "In terms of technology, there is no way that someone can move — a normal person would move from an Oracle database to an Amazon database," said Larry Ellison, chairman and CTO of Oracle. Amazon made its database technology available on the cloud long before Oracle did, Ellison said, but now Oracle is making its database technology readily available to customers in the cloud. The move lessens the chance customers will opt to move off Oracle technology. Such migrations are "just incredibly expensive and complicated and you've got to be willing to give up tons of reliability, tons of security, tons of performance to go ahead and do it," Ellison said.
