Our primary use case was to link about a hundred sites globally for a large company. The idea was essentially for cost-saving. They've got a large MPLS network with different providers with MPLS links and the idea was that in the first phase we would remove one of the MPLS links and then create a sort of centralized overlay that they could then have additional services to the remote sites and also give them a level of visibility globally across all their sites around the world.

The orchestrator was in the cloud but other parts like the hub site and data centers were obviously on-site and analytics were on-premises.
