Concept of Cashing in on the Cache in the Cloud
Source: The World
Over the past decades, caching has become the key technology used for bridging the performance gap across memory hierarchies via temporal or spatial localities; in particular, the effect is prominent in disk storage systems. Applications that involve heavy I/O activities, which are common in the cloud, probably benefit the most from caching. The use of local volatile memory as cache might be a natural alternative, but many well known restrictions, such as capacity and the utilization of host machines, hinder its effective use.
