1sockchuck writes "Sun Microsystems wants to cut its IT department's data center footprint in half within five years, and then eliminate in-house data centers completely shortly afterward. 'Our goal is to reduce our entire data center presence by 2015,' writes Sun data center architect Brian Cinque, who says Sun hopes to shift its in-house IT to a software-as-a-service model. Sun will use virtualization and consolidation to reduce its data center space and energy usage by 50 percent by 2013, with a goal of moving it all online two years later. Sun's plan reflects the shift to utility computing discussed in Nicholas Carr's new book, which we debated earlier this week."
