I've been an exclusive Microsoft developer since 1996. I still develop on a Windows computer to this day, mostly Node, Python, and C# .Net Core. and had no problems deploying everything on Windows servers. Then I discovered the cloud and moved into positions where the cost of infrastructure could easily be assigned to my implementations and I had to answer for the cost.

Once you add Windows to any implementation a few things happen. You pay more for licensing, you pay a lot more for resources (you can do a lot with 128MB/0.25 vCPU VM with Linux), and it is a much slower for VMs to scale in and out for elastic workloads like bringing instances up and down based on queue length.
