It appears that Sun is killing off its Sun Grid proto-cloud, the almost four-year-old Solaris 10-based utility computing platform offering grid compute time by the hour, only to replace it with some other form of cloud.

Exactly what remains cloudy.

The struggling company has a new cloud computing unit under SVP Dave Douglas, several hundred dedicated engineers and a cloud CTO, Lew Tucker, the guy who built Salesforce.com’s AppExchange marketplace, working on the vision.

Apparently Sun Grid only had a dozen or so customers that Sun will continue to support until it can shift them over next year to whatever new cloud model or models it lights on – perhaps a hybrid mix of public and private clouds.

According to a typically Sun notice now on the grid’s front-end, “Network.com is in transition as we add some exciting new options. We’ve not ready to show off what we’re working on just yet, but we’d like to hear from you, and we’d like to keep in touch.”
