Cost reduction and enhanced network performance are just two of the many benefits promised by SD-WAN technology. IDC believes the SD-WAN market will be a $6 billion industry by 2020, so it’s no surprise that solutions are popping up everywhere you turn.

At a high level, SD-WANs promise a more cost-effective and simpler way to operate secure, virtualized WAN connections between enterprise branches, data centers and the internet. Traditional MPLS links from the branch to the data center are reliable and secure, but typically offer lower performance for users accessing cloud-based services, and are considerably more expensive than widely available broadband access links.  The Internet provides global access to cloud applications, but is limited by poor reliability, unpredictable performance and weak security.

The benefit of SD-WAN is that it provides a software controlled and programmable environment that allows you to augment or replace your existing WAN, lower costs by leveraging cheaper broadband access links and dynamically scale bandwidth capacity to the cloud when needed.
