It's tough being an Azure fan
I once ran up a $15,000 bill on Azure completely by accident when trying to get one of their video processing services to work.  Once I figured out the service wasn't going to do what I wanted at a price I could afford, I tried to detach it and shut it down and thought I had succeeded.  I didn't.The offending process costing me money didn't appear on the Azure console and I had no idea it was running, how to access it to stop it or even to know what was going on.  When it turned up on my bill I nearly had a heart attack.Thankfully they let me out of it once I pointed out I was getting billed for something I couldn't see.  I appreciated that greatly but I've never gone back to Azure and the experience scarred me so much I don't think I ever will.  This was about 4 years ago so more than likely they have sorted it out.They keep reminding me I have $50 of test/dev credit on Azure through my Visual Studio subscription but it flat out frightens me to even try to use it.AWS isn't perfect but at least you have half a chance of working out what is costing you money through the billing console.
