I just read James Hamilton’s comments on “Microslice” servers, which are very low-power, but high CPU-to-wattage ratio servers. As he explains in detail, at scale the economics of this design are compelling. In some ways, of course, this is the opposite of another big trend going on, which is consolidation through virtualization. I reconcile these [...]
