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-When

The market believes that the key value of SD-WAN is the potential for cost savings of 50 to 90% compared to routed, legacy network services from telecommunications service providers. The time to use SD-WAN is anytime that managed network communications are not the core revenue source of the organization evaluating WAN solutions. SD-WAN offers superior resilience to network outages (blackouts) or network impedance (brownouts). SD-WAN offers superior quality mechanisms over policy-based routing. It also offers superior levels of security over routing and VPN-based solutions.

In the market, we have many sellers touting SD-WAN as a cure-all solution for network issues. Industry analysts believe that installing SD-WAN saves money. However, the technical debt from legacy solutions in production requires significant skill, time, changes, and financial resources to convert from a legacy WAN architecture to a SD architecture. The overhead from the redesign, education, and impact...
