        Gap Analysis of Interconnecting Underlay with Cloud Overlay
                    draft-dm-net2cloud-gap-analysis-01

Abstract

   This document analyzes the technological gaps when using SD-WAN to
   interconnect workloads & apps hosted in various locations,
   especially cloud data centers when the network service providers do
   not have or have limited physical infrastructure to reach the
   locations [Net2Cloud-problem].
