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.

SASE Orchestration

Scale is never achieved in a linear fashion as labor is never available at the rate of organizational growth. For an organization to scale at the pace of its growth, a non-linear or modular process is required. A successful process will require an understanding of architecture at both ten and one hundred times the currently needed sizing. Once the theoretical worst-case scenario is documented, the question of how must be asked. Assuming labor is static, how would it be possible to scale one hundred times the current size of the architecture? With human labor, it would be statistically impossible; therefore, non-human labor must be employed. Currently, the most effective way to scale infrastructure, virtual machines, or applications is to leverage an orchestrated model as well as an effective orchestrator. That orchestrator requires tools that abstract the process into modular components that are pre-built and made available on-demand.

In this chapter, we will...
