Diving into Secure Access Service Edge
By :

How to use SD-WAN is a common question today. SD-WAN should be used for most organizations as a site-to-site or site-to-cloud secure network communications platform, replacing routed wide-area-networks. SD-WAN should also be leveraged as the site-to-service connecting solution for SASE services. In the future, Zero-Trust Framework (ZTF) solutions will define the SD-WAN’s role in the infrastructure solutions portfolio further, but at this time, SD-WAN simplifies access to SASE.
To leverage SD-WAN, all current network architecture should be simplified, removing policy-based routing or prescriptive configurations. An open architecture must be leveraged to gain value from the SD-WAN solution. Most of the best-engineered WAN architectures in production today must be stripped bare of what made them effective to prepare for SD-WAN and SASE. The 180-degree shift in design is due to the separation of control and data plane functions. The control plane needs the ability to respond...
