Why not continue to use it as a cloud node?
I didn't even know that Oracle had a data centre there (but then I'm not involved in external data hosting), and had just assumed that the site had closed once SUN left.
And since "the cloud" is really nothing more than a clever collection of inter-connected data centres, if they no longer want to use it as a stand-alone data centre, why don't they just re-purpose it as a cloud node itself, rather than close it down?
On the other hand, Oracle, ugh. My workplace has recently started using an Oracle web-based system (presumably cloudy) for personnel records management (eg, requesting holidays) and job advertisements/applications, and, yuk, it has as user-unfriendly a UX/UI as you might expect.
