Hub & Spoke topology for globally spread locations

[SandeepS]

Dear Experts,

I have couple of questions on SD-WAN design :

Let's say I have 2 DCs and 100 Branches across the globe. I want to connect all these 102 sites through SD-WAN which are connected to different transport of different service providers local in the country.

1. In such case - Is it ok to have them under 1 SD-WAN domain (i.e. all 102 sites managed by centrally placed vManage, vSmart & vBond) ? I want to put them on-prem, not cloud.
2. Also, any idea on How much approx. latency can be added if I put SD-WAN overlay in such scenario?

Regards,

SS

1. It's ok to have them all under 1 SD-WAN domain since you can build any arbitrary topology
2. very little, just few msec, you should mainly concern about latency of your links in my opinion
