At Microsoft if you build a product using Azure (and if you want to use the cloud you MUST use Azure, you're not going to get approval to write a check to AWS)

At Microsoft if you build a product using Azure (and if you want to use the cloud you MUST use Azure, you're not going to get approval to write a check to AWS) the costs come out of your budget. And it's taken seriously, to the point where teams will very much emphasize managing costs (what will this new feature cost on our Azure bill? Can we build it more efficiently? Oh wow, that refactor saved us 100k/month in cloud costs, don't forget that when we start talking about promotions...)
