Oracle is living on borrowed time. They secured vendor lock-in by selling custom solutions to big name industries -- hotels, finance, etc. Now its common knowledge that buying Oracle is selling your soul. There's no way out once you're in. I haven't seen a single startup running on Oracle -- because their pricing is so out of whack when compared with the alternatives that no one in their right mind would launch with Oracle as a dependency. Oracle has been selling the same old stuff for decades with hardly a blip on the innovation radar. Meanwhile open source database engines are being ran in production at scale without a hitch.
Cloud providers are making money not off the database software -- but from managing the infrastructure needed to scale, backup, and secure those databases. They are providing actual value to their customers, rather than asking for a pound of flesh.
If Oracle wants to keep their golden spot in the sun its time they stopped resting on their laurels and started giving their customers a fair shake.
