Looking at quarterly growth since Q1 2013 it turns out that AWS revenue is vulnerable for price cuts. Q1 2014 growth slowed to 9% and Q2 2014 declined 4% against Q1 as the result of a series of price cuts, ranging from 28 percent to 51 percent. The price cuts impacted profitability as well; margins dropped from 23% to 8% in Q2 and Q3 2014. Profit margins for Q4 2014 and Q1 2015 increased again to 17%.
The price cuts also had an effect on AWS twelve month trailing (TTM) revenues as TTM growth dropped from 14% in Q1 2014 to 9% in Q2 2014. TTM growth is now at 11% and currently AWS annual revenue is $5.2B.
