Providing Statistical Reliability Guarantees in the AWS Spot Tier
Rich Wolski, John Brevik · 2016
In this paper, we present DrAFTS -- a methodology for predicting the value a user should bid in the AWS Spot tier to ensure that the request lifetime exceeds a fixed duration with a given probability. DrAFTS uses previous price histories for each category of request to determine both the minimum bid value and the concomitant duration associated with that value that is "guaranteed" with a specified probability. We also describe how DrAFTS can be used to determine the duration associated with over-bidding the minimum by a specific percentage.
