Google Cloud is not just App Engine now. Its pretty much the equivalent to aws in features. Let me also say I have PhD in Cloud and big data (graduated in 2013), worked for Amazon aws, worked for an rackspace for year and half, I was a core contributor to OpenStqck for the products OpenStack Poppy and OpenStack Zaqar. I hope you his puts se more weight behind my statements. If you are interested to know the details and why Google Cloud is better that aws for 90% of products, reach out to me.
