Top tips for greening your data center
Data center operators, and those that use them, are under increasing pressure to go green. Demand for data center capacity is being driven up by a number of factors that make driving efficiency through green principles a complex process. But, the introduction of new emissions laws, such as the UK Carbon Reduction Commitment (CRC) Energy Efficiency Scheme makes the greening of the data center inevitable. The CRC has been causing great concern for data center professionals, who also need to save money on energy

It describes the cloud as "both a friend and a foe" from a security point of vi
