Smart Access Gateway (SAG) allows you to connect a private network to Alibaba Cloud
through a leased line, Internet connection, or both. If you choose to use a leased
line, you must associate the SAG instance with a virtual border router (VBR). If you
choose to use an Internet connection, you must associate the SAG instance with a Cloud
Connect Network (CCN) instance.
Prerequisites
- Before you connect your private network to Alibaba Cloud over the Internet, make sure
that a CCN instance is created. For more information, see Create a CCN instance.
- If you choose to use a leased line, make sure that the leased line is deployed in
your private network and a VBR is created. For more information, see What is Express Connect?.
