Connection scenarios
A hybrid cloud connects your on-premises data center to the Alibaba Gov Cloud platform. This setup is useful if you want to deploy parts of your business across both environments or if your on-premises business needs to use services on Alibaba Gov Cloud. You can use an Express Connect circuit to connect the two environments.
To connect to the Alibaba Gov Cloud platform over an Express Connect circuit, you can lease a line from a carrier. This line connects your on-premises data center to an Alibaba Gov Cloud access point. After the connection is established, you can create a virtual border router (VBR). The VBR connects your on-premises data center to the Alibaba Gov Cloud platform and creates a hybrid cloud environment. This setup enables cloud resources to access your on-premises data center over a private network, bypassing the Internet.
A connection over an Express Connect circuit does not use the Internet. This provides greater security and reliability, higher speeds, and lower latency.
An Express Connect circuit that connects on-premises and cloud-based operations is suitable for the following two scenarios.
Partial cloud deployment

- For this scenario, the leased line must not exceed 50 km in length.
- The bandwidth of the leased line is customizable and can be scaled out as needed.
Use of cloud security capabilities

- For this scenario, the leased line must not exceed 50 km in length.
- The bandwidth of the leased line is customizable and can be scaled out as needed.
