[HAIFUX LECTURE] Deconstructing Amazon EC2 Spot Instance Pricing by Orna Agmon Ben-Yehuda

[Eli Billauer]

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.
