I know a new technology that is being utilized is SDWAN to maximize network flow and use a secondary line.  How does SDWAN work?  What is the difference between SDWAN and MPLS?  Have any of you experts had experience with it and do what do you like about it?

SD-WAN shifts traffic monitoring and management from physical devices to the application itself, capitalizing on SDN's flexibility and agility. Intelligence is abstracted into a virtual overlay -- enabling a secured pooling of both private and public connections and permitting automation, centralized network control, and agile, real-time traffic management over multiple links. This model enables a network administrator to remotely program edge appliances via a central controller, reducing provisioning times and minimizing or eliminating the need to manually configure traditional routers in branch locations.

If you're familiar with MPLS, SD-WAN is an intended replacement of that. It's intention is to allow the consumer to leverage an MPLS-like solution over a standard broadband connection, instead of over expensive commercial circuits. The good providers have WAN optimization built into their product as well (e.g. Silver Peak), so you really can run sensitive applications like VoIP over standard broadband connections.

Where are these hosted applications? Azure, AWS, etc. or hosted on the providers' own network? SD-WAN employs a "bookshelf" like design which means you need implementation of the technology on both ends, e.g. on client end and resource end.

Ok, but if I assume that the virtual server that's hosting the IP PBX is not on infrastructure you manage, then your options might be a little limited. Can you share with us what cloud platform you're going to host the Virtual Server/IP PBX?

Also, what kind of internet connection do your 100 users sit behind? Is there any other interesting traffic load being put on that connection currently, other than just general web use, email, etc.?

Silver Peak (www.silver-peak.com) has a product that would work. Their EdgeConnect solution can be deployed as a virtual appliance (so no upfront hardware costs). It employs all what you would expect with SD-WAN, but also includes WAN optimization. If you're virtualizing locally I would suggest deploying 2 EdgeConnect virtual appliances (1 locally and 1 with Singlehop) and managing the system with Silver-Peak's Unity EdgeConnect UI.
