PA-SDWAN setup using MPLS & Internet links

[Yuvaraj.Karvekar]

Hi Experts, 

I am planning to Implement the PANOS SDWAN in our environment, having 2 DC's & 5 Branches & Multiple cloud regions(two)  

I have question about ISP links to use for PANOS SDWAN

.

Currently I am having one MPLS & one Internet link from DC to Cloud.

I have more traffic volume from DC to Cloud regions.     

Option#1

1. Use MPLS link from DC to CLOUD for PANOS SDWAN

2. Use MPLS for SDWAN is good practice from DC to Cloud? Traffic volume from DC to cloud is more.  

2. If I use the MPLS for SDWAN, Throughput will be maximum of 1.5Gbps via IPSec? 

What is the preference for the underlay links for SDWAN from DCs to Cloud?  MPLS vs Internet

Option#2

1. Pure MPLS from DC to Cloud -Primary 

2. Internet with PANOS SDWAN - Secondary 

Are the above options being correct?  and which one is best for my environment please? 

Thanks & Best Regards
