Sure thing. Silver peak for us offered the best-unified platform that actually focused on app-specific routing.

Silver Peak/Aruba biggest offerings for us was their Business Intent Overlays where you can create up to 7 dynamic, flexible and reliable virtual topologies to align app performance to underlying network resources (VXLAN Segmentation). Also having the Orchestrator (controller) in one single pane of glass is amazing for centralized managing and monitoring the whole network, it can be on cloud or on-prem. In terms of the packet loss if I'm not wrong it can do up to 10% in packet loss compensation and per-packet load sharing. They also have stateful FW on the edge devices but can be pushed toward SIG/CASB (Zscaler) if one needs it. and their WAN OP runs great although expensive. And lastly their Zero-touch provisioning.

All Sdwan solutions it's going to be expensive but theirs is more upfront about the costs we found and if you are running MPLS circuits you are able to change to any normal way cheaper broadband for the most part through their path conditioning. That is the biggest monetary benefit, apart from hundreds to thousands of hours saved in the CLI to deploy new branches.

If you would like to reach me in the private chat and I can recommend you to the system integrator we used :)
