Smart Access Gateway (SAG) provides different scenarios with solutions to migrate workloads to the cloud. You can choose a suitable network topology based on your actual requirements.

Connect mobile devices to Alibaba Cloud

To connect mobile devices or remote devices to Alibaba Cloud, you can use SAG APP. SAG APP supports dial-up access from client devices such as PCs and mobile phones to Alibaba Cloud. Network connections between private networks and Alibaba Cloud are encrypted. SAG APP is suitable for office automation and remote operations and maintenance.

Connect small-scale networks to Alibaba Cloud

To connect small office branches or stores to Alibaba Cloud, you can deploy SAG devices in inline mode.

Before you deploy an SAG device to connect a small-scale network to Alibaba Cloud, we recommend that you purchase a 4G subscriber identity module (SIM) card and insert it into the device. The 4G SIM card provides standby network connections. When an error occurs to the active network connection, data transmission is automatically switched to the standby connection. This improves network reliability. inline mode

Connect large-scale networks to Alibaba Cloud

To connect large-scale networks to Alibaba Cloud, you can deploy SAG devices in one-arm mode.

Before you deploy an SAG device to connect a large-scale network to Alibaba Cloud, we recommend that you purchase a SIM card and leased line. In this way, the broadband network, 4G network, and leased line are deployed in active-standby mode. This improves network reliability.

  • Deploy a leased line (connected to an SAG device) to set up standby network connections
    If you connect a leased line to the SAG device deployed in your network, local network traffic is transmitted through the leased line preferentially. leased line to alicloud
  • Deploy a leased line (connected to a local Internet-facing device) to set up standby network connections
    If you connect a leased line to a local Internet-facing device, you can prioritize the use of SAG and local devices for data transmission. leasedline and SAG2
