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.

Forward Measured

How do you measure the future? How do you predict what is going to happen and when? A correct response is that you cannot measure the future; however, without measurement, how do you prepare?

In actuality, the future is predictable, as every living thing follows a pattern of behavior that has minor variances. If we simply study the history of a subject that we would like to predict future outcomes for, we can see a pattern in reverse, starting from today and going back to inception. To predict the future outcome, we place the timeline from today going forward, leveraging the ratios and frequencies from the historical pattern, and applying the same pattern to the future. The frequency of repetition or iteration when studied from inception to the present shows slower, faster, or stable occurrences of the pattern, which we can apply to our future prediction with the assumption that the pattern will be repeated until catastrophic circumstances cause it to change.
