With the cloud wars "on" according to a Forbes article by Bob Evans, Microsoft is on track to hit $7 Billion on Quarterly cloud revenue and Amazon at $6 Billion
Microsoft has a good chance of becoming the first tech vendor to reach $7 billion in quarterly commercial-cloud revenue when it releases earnings on July 19 while Amazon could very well hit $6 billion in AWS revenue when its numbers come out later in the month.
While Microsoft doesn't reveal its exact Azure earnings, Canalys estimates Azure revenues in Q2 were 18 percent of the total cloud infrastructure spend. Google Cloud CEO Diane Greene told CNBC she thought that people were underestimating the scale of Google’s cloud businesses and she thinks that’s still the case today, too.

Businesses are assessing ongoing public cloud cost as well as usage rates to determine the best option for their workloads. This will result in some remaining on-premises, some moving to public cloud providers and some returning from public to private clouds
