This approach created an expensive environment with a large failure domain. Later in the early 2000s, the focus switched to scaling out servers because the hardware had evolved to a commodity model with fewer CPUs. It focused mostly on the x86 platform using commoditized operating systems hosting a single application per server. This approach caused an increase in power and cooling requirements and produced underused servers. In today’s ...
