"... here is the CPU usage over a day in one of our data centers where each time series represents one machine and the different colors represent different generations of hardware. Unimog keeps all machines processing traffic and at roughly the same CPU utilization."
Still a mystery to me why "balancing" has SO MUCH mindshare. This is almost certainly not the optimal strategy for user experience. It is going to be much better to drain traffic away from older machines while newer machines stay fully loaded, rather than running every machine at equal utilization factor.
