The truth is that you can keep throwing CPU at a problem as well. I can size a software based router such that it can remain available.
Not against mpps, or even high kpps, you can't, unfortunately.
Software based platforms have an incredible edge in areas that hardware based platforms don't, including capex and the ability to find replacement parts after a disaster.
I agree 100% with this, and with much of what you say.
