Diving into Secure Access Service Edge

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.

Management Overview

The approach to managing SASE should be novel when compared to previous systems. For many years, IT professionals have striven to create effective management systems, ultimately finding the solution elusive. Today, taking lessons learned from the telecommunications service providers, we leverage the concept of service orchestration beyond manufacturer-specific tools. Service orchestration is not new but is commonly misrepresented in marketing language to drive revenue.

For the purposes of SASE management, each manufacturer provides one or more orchestrators, element managers, management tools, or other systems for the purpose of managing one or more SASE services. The challenge presented here is that many organizations may have several dozen SASE services in production requiring separate orchestration. The complexity of service management and the need to implement solutions in real time are the two primary reasons for outsourcing SASE management.
