We estimate that Google’s Cloud business will exceed $50B in annual revenue this year with Google Cloud Platform comprising more than 50% of its cloud revenue for the first time ever. Why is it then that Google’s cloud business, a $50B+ entity growing deep into the double digits gets so much criticism? The answer is simple. Google’s cloud, with arguably the best technology in the industry, is 2.5 - 3.5 times smaller than the cloud businesses of AWS and Microsoft.
