There has been a lot of teeth gritting over how locked into AWS certain parts of a customers company has become, using their API's, their services, and with no real way to move away if anything ever happened.
AWS has already perfected vendor lock-in, so I doubt Oracle can make it much worse, beyond their normal trick of de-certifying their products on competing platforms.
Doesn't matter, its the outsourcing of this decade. Every board wants to be in the cloud, because it gives the (stock) market the impression the company is going places.
And everyone from Oracle to MS, and Google as well, wants to be the one to rent them that cloud, Hotel California style.
Thats why MS has changed their tune regarding Linux, as long as it is running in a VM on top of their Azure service...
