For our case, the need is very specific as we are working with mobile apps.

Building iOS apps require macOS and even though there are some well-known "Mac hosting" services, none of them are actual cloud services similar DigitalOcean, Azure, AWS, etc.

So it is much less expensive and actually easier to scale and configure to host the Macs onprem.

(Off the record: If it is for internal use only, you can even stick in a few hackintoshes for high performance.)
