Abstract: This study examines cloud computing spot pricing dynamics and the influence of latency on those pricing dynamics. Using the Amazon Elastic Compute Cloud U.S. East and West market spot instance pricing and latency intraday data from April 9, 2010, to May 22, 2011, we find considerable time variation in spot instance prices, and prices are often persistently higher in the West. Bivariate vector autoregressive model results show that within-market autoregressive pricing effects are larger than across-market effects. We also document that over 70% of the relative price discovery occurs in the East market. Our regression results further show that East–West latency differentials have a significantly positive effect on East–West pricing differentials. Latency creates a dynamic pricing wedge that widens or narrows conditional on the latency differentials. Using an error correction model, the speed of adjustment from long-run pricing convergence errors causes the short-run price differential to narrow, but the adjustment does not completely offset the price differential.
