On Monday, September 26th (TOMORROW), at 18:30, Haifux will gather to
hear Orna Agmon Ben-Yehuda talk about
Deconstructing Amazon EC2 Spot Instance Pricing
Abstract
Cloud providers possessing large quantities of spare capacity must
either incentivize clients to purchase it or suffer losses. Amazon is
the first cloud provider to address this challenge, by allowing clients
to bid on spare capacity and by granting resources to bidders while
their bids exceed a periodically changing spot price. Amazon publicizes
the spot price but does not disclose how it is determined.
By analyzing the spot price histories of Amazon's EC2 cloud, we reverse
engineer how prices are set and construct a model that generates prices
consistent with existing price traces. We find that prices are usually
not market-driven as sometimes previously assumed. Rather, they are
typically generated at random from within a tight price interval via a
dynamic hidden reserve price. Our model could help clients make informed
bids, cloud providers design profitable systems, and researchers design
pricing algorithms.
