Interesting that Oracle worries about "lock-in"
"Summing up its position in a statement to The Register, Oracle said that JEDI “virtually assures DoD will be locked into legacy cloud for a decade or more” at a time when cloud technology is changing at an unprecedented pace."
That's exactly Oracle's model - hook them and then lock them in. Maybe the DoD in this procurement was just using Ellison's example. And, of course, Oracle has been a real laggard in trying to play with the cloud.
