I am also using Amazon and when I compare it, it requires a bit more stability. Amazon Cloud Services are a bit more stabilizing, at least with basic computing. Amazon by default is SSD only. When you create an instance in Google, by default it allocates to the disk and there are some performance issues. When you compare it with Amazon, the performance is a bit slow. In the next release, I would like to see the issue with the stability resolved. I have not faced any issues with freezing or hanging when using Amazon.
