But it looks like the cloud industry is still growing. And in very big way.

The world’s largest cloud computing services — services where you can run software and store data without buying your own hardware — are run by Amazon, and according to a new study from independent researcher Huan Liu, Amazon’s operation grew by a whopping 62 percent over the past two years. What’s more, the study shows that growth has been steady since June 2013, when the Snowden revelations first hit the news. In fact, there’s been a surge since December of last year.

Liu’s research does not look at services from Amazon rivals such as Google, Microsoft, or Rackspace. But Amazon is the best barometer for the market as a whole. Software running on Amazon Web Services may account for as much as 1 percent of North American traffic, according to data collected by DeepField Networks, and about one-third of all North American internet users visit at least one site hosted in the Amazon cloud each day.
