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-WAN Overview

Before we delve deeper, it is important to know what SD-WAN is. SD-WAN stands for Software-Defined Wide Area Network. As the name suggests, SD-WAN utilizes a software mechanism as defined in the policy to make path selection decisions as opposed to routing protocols. SD-WAN consists of hardware devices and software implemented across a highly distributed system. It uses software instead of routers to direct digital traffic.

SD-WAN can leverage any physical type of connection to forward traffic across. Commonly, SD-WAN will use private network connections such as MPLS, Metro Ethernet, dedicated fiber Ethernet, point-to-point wireless, or private satellite and cellular connections. Public connectivity to the internet across 4G, 5G, broadband, or satellite connections is used on an equal basis as all connections are securely tunneled with equal levels of encryption and treated as insecure. In this way, both public and private network paths are treated as VPNs and all...
