At Oracle's annual OpenWorld megaconference last month, top executives from the old enterprise software company were smack-talking Amazon's cloud business. They claimed a workload on Amazon could be nearly six times more expensive than on Oracle's cloud.
It was the latest chapter in what's become a war of words between a pair of unlikely adversaries. Who would've thought five years ago that a massive developer of databases and business software would be going head-to-head with an e-commerce giant?
Now it's Amazon's turn, again. Andy Jassy, CEO of Amazon Web Services, delivers his keynote address Wednesday morning at the re:Invent conference in Las Vegas.
Before taking the stage, Jassy told CNBC that Oracle was still far behind in the cloud.
"I think they're a long way away in the cloud," Jassy said.
