Upgrade to SD-WAN To Improve Cost and Performance

Description: The Corporate WAN is a huge cost of between 40-80% of networking budgets. In 2015, Software Defined WAN rapidly emerged offering a way to quickly cut those costs by using the Internet, improve application performance and implement network monitoring so that service providers are being held to account for poor services.
This session covers the business & technology factors that drive the Software Defined WAN so that you can be informed on why and how you should be implementing it.
