Also you should consider that the more you scale, the more "scaling in the small" saves you money/machines/operators/... Why ? Less resource-hungry code requires less resources and doesn't cause problems quite so quickly (tends to cause harder problems though). 8 years ago I switched the directory on a site that required >30 servers to run to tmpfs, and did some serious sql optimization in the php code. The month after that I turned down 20 of them (actual servers + caching and load balancing servers that weren't necessary anymore). |
