Tim,
I have been tasked with creating an Arc Enterprise deployment in a cloud environment and have also been looking at google since they are about half the price as AWS. I know there is some "conflict" between ESRI and Google due to Google Earth, but cloud server wise, i dont see how it would matter. A linux server instance is the same machine regardless if it runs in AWS/Azure/Google...I think. Did you go with google, do you have any insights.
Thanks, Mike
