Facebook 的 Autoscale 對於電力消耗的差異

在「Facebook’s New Cluster Management Software Cuts Power Consumption」這篇看到 FacebookQiang Wu 說明了他們發展的 Autoscale 技術對於電力消耗的差異:

One type of a web server Facebook uses, for example, draws 60 watts when idle, 130 watts at low-level CPU utilization and 150 watts at medium-level utilization.

利用這種差異,與傳統的 load balancing 技術比較起來,就有節省的空間了:

這是 web cluster 節省的情況,約省了 27% 的電力,這個數字以 Facebook 的規模來計算省下的電力資源超級可觀...
