Automate setting up and managing your transit networks with AWS Transit Gateway

Publication date: November 2019 (last update: January 2023)

The Network Orchestration for AWS Transit Gateway solution automates the process of setting up and managing transit networks in distributed AWS environments. A web interface is created to help you control, audit, and approve (transit) network changes. Network Orchestration for AWS Transit Gateway supports AWS Organizations and standalone AWS accounts. You can use this solution with the default deployment template, or customize it to meet your specific use case.

AWS Transit Gateway connects Amazon Virtual Private Cloud (Amazon VPC) and on-premises networks through a central hub that controls how traffic is routed among all the connected networks, which act like spokes. This hub and spoke model simplify network management and reduces operational costs because each network only connects to AWS Transit Gateway. Any new VPC or subnet that is connected to AWS Transit Gateway is automatically available to every other network connected through AWS Transit Gateway.

This implementation guide discusses architectural considerations and configuration steps for deploying the Network Orchestration for AWS Transit Gateway solution on Amazon Web Services (AWS). It includes links to AWS CloudFormation templates that launch and configure the AWS services required to deploy this solution using AWS best practices for security and availability.

The guide is intended for IT infrastructure architects, administrators, and networking professionals who have practical experience with networking and architecting in the AWS Cloud.
