Ginseng: market-driven memory allocation
Abstract
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.
Joint work with Eyal Posener, Muli Ben-Yehuda, Assaf Schuster and Ahuva
Mu'alem.
