For example, the realization of privacy in clouds is a cross-cutting interdisciplinary challenge, permeating the entire stack of any imaginable cloud architecture. The goal of this

Such settings involve large numbers of multicast groups as well as multiple senders to each group — a single system can have hundreds of such multicast channels. Without ef- fective multi-channel rate control, multicast senders

In tradi- tional systems the focus has been on maximizing paral- lelism, for example by laying out data to achieve the highest throughput. However, in a massive scale database such as our PNUTS system (11) or BigTable (10), maximizing par- allelism is not

In this paper, we present a scalable and efficient peer- to-peer system with a new search primitive that
