Server configuration for 450 concurrent streams on WSE?

What should be my server configuration if I need to stream 450 concurrent stream sources, at 480p 500kbps (bitrate) without any transcoding, and the the viewership is a single viewer for each of the 450 streams (similar to monitoring setup)

AWS/Azure/ Inhouse server configuration required. And if possible are there any articles that will be useful to refer to come up with this figure of configuration based on the requirements?

And can WSE handle 450 concurrent streams?
