Poll: What cloud services provider do you use?

Having worked only with AWS running several large production and staging workloads for a long time now I'm curious about what others are using. Please leave some feedback on your experiences with others (positive or negative).

I'm mostly talking about services that provide full control over machines (so not Heroku) and also alternative services such as Lambda or some machine learning tools, etc (so not Digital Ocean even though I love them).

Thank you!
