mAny people ReADinG about cloud computing in the
trade journals will think it’s a panacea for all their
IT problems—it is not. In this CTO Roundtable
discussion we hope to give practitioners useful
advice on how to evaluate cloud computing for their
organizations. Our focus will be on the sMB (
small-to medium-size business) IT managers who are
underfunded, overworked, and have lots of assets
