	abstract = {<div>Everyone loves a large caching tier in their multi-tier cloud-based web service because it both alleviates\&nbsp;database load and provides lower request latencies. Even\&nbsp;when load drops severely, administrators are reluctant to\&nbsp;scale down their caching tier. This paper makes the case\&nbsp;that (i) scaling down the caching tier is viable with re-\&nbsp;spect to performance, and (ii) the savings are potentially\&nbsp;huge; e.g., a 4x drop in load can result in 90\% savings in\&nbsp;the caching tier size.</div>
