Hi, I have a question regarding COR (Cloud OnRamp).
Question 1 - SaaS
I understand that if we have two service providers, we can send HTTP probes to our SaaS application and determine the quality (QOE) of both connections and then pick the one that is currently performing better.
This example makes great sense but every single resource mentions another example where we have just one internet circuit and then an MPLS circuit.
14:20 on the YouTube video.
My question is, why isn’t SD-WAN running over the internet circuit? I thought we’d use it since we have SD-WAN.
Question 2 - IaaS
If I understand this right, we can literally deploy a vEdge router.. inside our cloud’s IaaS service? 
Which would mean that we can connect the IaaS into our SD-WAN service.
What benefits does this offer? Apart from, again, being able to determine what wan circuit might be the best to access the IaaS infrastructure, what else does it do? Can the IaaS infrastructure also decide from their side which WAN circuit they want to use? (Considering that we can use IPSec, private WANs, internet, literally almost anything to connect to the cloud).
With SaaS, the benefit is limited to “yeah this path is better, we will use it” and not much else, or? Does this change with IaaS?
