Many organizations are struggling to provide high bandwidth and reliable internet connectivity at their branch offices and business locations and getting the most out of their operational expense. The need for internet connectivity at any branch offices and business locations is no longer a luxury but is a necessity. Let us try to understand how to replace the traditional MPLS network with the new SDWAN (Software - Defined- Wide Area Network) technology. We will try to understand why it is essential to implement the latest technology instead of investing in the existing MPLS (Multi- Protocol label switching) by taking an example of a retail organization. We also have a look at how to evaluate the product by using some metrics and how different teams are involved during different phases of the project.
