economy, such as connecting enterprises' branch offices to dynamic
workloads in different Cloud DCs.
This document analyzes the technological gaps to interconnect
dynamic workloads & apps hosted in cloud data centers that the
enterprise's VPN service provider may not own/operate or may be
unable to provide the enterprise with the required connectivity to
access such locations. When VPN service providers have insufficient
bandwidth to reach a location, SDWAN techniques can be used to
