With AWS Cloud WAN, you can use a central dashboard and network policies to create a global network that spans multiple locations and networks, allowing you to configure and manage different networks using the same technology. You can use your network policies to specify which of your Amazon Virtual Private Clouds, AWS Transit Gateways, and on-premises locations you want to connect to by using an AWS Site-to-Site VPN, AWS Direct Connect, or third-party software-defined WAN (SD-WAN) products. The Cloud WAN central dashboard, powered by AWS Network Manager, generates a complete view of the network to help you monitor network health, security, and performance.
