BLOG: The data centre renaissance

Andrew Milroy | March 6, 2012
Once viewed as soulless grey rooms, data centres are now seen as the foundation of the hottest topic on everyone’s lips – cloud computing.

#3 Energy Efficiency. The enormous power demands of today's data centres are not only difficult to meet, but also increasingly expensive. The cost of providing power to data centres is now becoming a very significant line item. It is a cost which can be managed. Data centres must be designed in a way that maximises energy efficiency. This may include the use of on-site power generation or/and the use of renewable energy sources. Metrics such as Power Usage Effectiveness (PUE) should be used to maximise energy efficiency.

#4 Location. Latency is directly related to the location of a data centre. The organisations that place the highest demands on IT require the lowest latency, and consequently they require a data centre that is located near to the bulk of IT use. Data sovereignty is also a major issue leading to growing pressure for data centres to be built in the country where most usage is anticipated.

#5 Security. As I have mentioned in earlier posts, centralised IT architectures are innately more secure than distributed architectures because they have fewer points of vulnerability. However, this assumes that data centres are adhering to security best practices. In addition to best practice IT security, data centres should follow physical security practices such as video surveillance and biometric identification.

The enablement of cloud computing is dependent on these data centre-related considerations. Perhaps, the most important issue is to ensure that data centres have the capacity to guarantee the optimum performance of applications that are delivered from remote data centres, securely.
