About the 4-D documentation series

Fortinet Secure SD-WAN documentation is categorized into four distinct documents (called 4-D documents): Define, Design, Deploy, and Demo. Each document is designed for a specific purpose and builds on the other documents by providing you a complete path from beginning to end.

The 4-D documentation series includes the following components:

• Design: Conceptual guide meant to introduce the reader to common SD-WAN use cases and the Fortinet Secure SD-WAN solution
• Design: Reference architecture guide that provides an overview of the components and architectures to satisfy common uses
• Deploy: Deployment guides that provide step-by-step procedures for deploying the desired architecture
• Demo: Github repository of the configuration and examples provided by subsequent documents

The architecture, components, and technology referenced in this document are covered in the Single datacenter (active-passive gateway) section of the SD-WAN Architecture for Enterprise guide.
