This is a review of the talk given by Luiz Andre Barroso on the comparison between the current warehouses and those of 10 years ago. He also talks about the various challenges of the current Warehouse Scale Computing (WSC).
Firstly, power management. It is quite a feat manage/regulate the power consumption for a WSC because it's not rare to have fluctuations that may cause an overload which is dangerous. On the other hand, not utilizing the power to its fullest capacity is cost expensive. One solution that Barroso offers is that having UPS per server so as to allow the servers can temporarily produce powers that are above its specs.
Storage is also a major component in WSC. Having a decent storage systems will give the cloud providers an edge over its competitors to provide better user experience in general. With the birth of new classes of storage devices, flash-based ones, that's worth considering. Although it has a very high performance of random reads compared to its traditional hard-drive counterparts, sometimes sequential writes is better performed in traditional hard-drives.
Moreover, the networking aspects of WSC is also essential to be improved upon since having a very high performance storage system but a subpar networking connectivity performance is of no use. On the other hand, providing a high networking bandwidth in the whole datacenter is exorbitant, and thus undesirable.
