    Ginseng: market-driven memory allocation


Physical memory is the scarcest resource in today’s cloud computing 
platforms. Cloud providers would like to maximize their clients’ 
satisfaction by renting precious physical memory to those clients who 
value it the most. But real-world cloud clients are selfish: they will 
only tell their providers the truth about how much they value memory 
when it is in their own best interest to do so. How can real-world cloud 
providers allocate memory efficiently to those (selfish) clients who 
value it the most?

We present Ginseng, the first market-driven cloud system that allocates 
memory efficiently to selfish cloud clients. Ginseng incentivizes 
selfish clients to bid their true value for the memory they need when 
they need it. Ginseng continuously collects client bids, finds an 
efficient memory allocation, and re-allocates physical memory to the 
clients that value it the most. Ginseng achieves a 6.2x-15.8x 
improvement, which is 83%-100% of the optimum, in aggregate client 
satisfaction when compared with state-of-the-art approaches for cloud 
memory allocation.
