1sockchuck writes "An architect of the Windows Live team has published a presentation advocating portable container-based data centers as the future of data center infrastructure. James Hamilton, who previously was GM of Microsoft Exchange Hosted Services, contends that a distributed network of unmanned modular units 'transforms data centers from static and costly behemoths into inexpensive and portable lightweights. ... Multiple smaller data centers, regionally located, could prove to be a competitive advantage.' Both Sun and Rackable have rolled out prototypes of container-based 'data center in a box' products, and Hamilton notes that large generators are also available in trailers."
