Diving into Secure Access Service Edge

By: Jeremiah

Overview of this book

The SASE concept was coined by Gartner after seeing a pattern emerge in cloud and SD-WAN projects where full security integration was needed. The market behavior lately has sparked something like a "space race" for all technology manufacturers and cloud service providers to offer a "SASE" solution. The current training available in the market is minimal and manufacturer-oriented, with new services being released every few weeks. Professional architects and engineers trying to implement SASE need to take a manufacturer-neutral approach. This guide provides a foundation for understanding SASE, but it also has a lasting impact because it not only addresses the problems that existed at the time of publication, but also provides a continual learning approach to successfully lead in a market that evolves every few weeks. Technology teams need a tool that provides a model to keep up with new information as it becomes available and stay ahead of market hype. With this book, you’ll learn about crucial models for SASE success in designing, building, deploying, and supporting operations to ensure the most positive user experience (UX). In addition to SASE, you’ll gain insight into SD-WAN design, DevOps, zero trust, and next-generation technical education methods.

SD-How

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...
