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.
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.
- 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.
