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.

Design Theory

Production goals are exactly that, they are goals. Measuring finite, reportable metrics in production is always wrong as it produces the wrong organizational behavior. If you substitute the User Experience (UX) for previous methods of measurement, human behavior starts to align with the reason that performance was measured. The temptation is to measure and manage by all available metrics. This has consistently proven to produce the wrong human-based results. This is a good point to insert AIOps for the system or service to be managed, whereas the human is charged with positive UX.

Design theory for SASE has not been written at the time of authoring this book. Practitioners of SASE subscribe to ZTF mixed with DevOps concepts. In each case of successful SASE Service deployment, the separation between the data plane and the control plane is observed. Additional planes are identified based on perspective and the design of the services as provided by the developer or service...
