Simplify Network Management from Jack prabha's blog

Because SD-WANs are software controlled, it is easier to add features and functions from a central location, while also reducing the need for edge appliances (e.g., WAN optimization and firewall boxes). SD-WANs delivered as a service over a private network also make it possible to deploy a global enterprise WAN without sourcing and procuring MPLS providers around the world.

MPLS never got the memo about the speed of business changing, because adding new locations can still take weeks, if not months. With SD-WAN, new locations can be brought up in days. What’s more, Aryaka’s Global SD-WAN encrypts traffic end-to-end, which isn’t offered with MPLS and may be an important compliance consideration.

Speed up your applications no matter where they are hosted. An SD-WAN, with built-in WAN optimization, improves performance for all mission-critical applications, hosted on-premises or in the cloud. And if you choose an SD-WAN delivered as a service over a private network, you can realize consistent application response times for users anywhere in the world, and sidestep the performance problems that plague SD-WANs that use Internet transport.
