Amazon "other revenue" over time
This graph shows that since EC2 and S3 launched in 2006, earnings in Amazon's "other revenue" section have increased dramatically year-on-year with an accelerating growth curve that closely corresponds to datacentre expansion by Amazon and growth in the number of technologies and services offered on top of the platform.
Even if we take the conservative assumption of only 50 percent of the "other revenue" figure representing Amazon Web Services (AWS), the growth is impressive.
