Step 5: Configure a NAT Gateway Create a NAT gateway. Log in to the console and search for NAT Gateway in the Service List. The Public NAT Gateways page of the network console is displayed.
The child device connects to the gateway, and the gateway authenticates the child device. The child device reports data to the gateway.
A proxy server works as a gateway between your source environment and the Internet. When directly accessing a cloud service, the source server to be migrated sends a request to the cloud service, and the cloud service responds to the source server.
A proxy server only works as a gateway between you and the Internet. It has no specific requirements on the OS and specifications. Only if there are too many source servers, such as more than 100 servers, the performance of the proxy server will be affected.

Example: An enterprise has a batch of gateways under a gateway product. About 400 child devices are mounted to a gateway. Administrators need to check gateway statuses in real time to ensure that child devices report data properly.

Introduction to the application: The application contains the following microservices, each of which contains an instance: vmall-apigw-service: API gateway, which is responsible for service authentication, request throttling, and filtering.
Gateway Response: Select default. Authentication Mode: Select Custom. Custom Authorizer: Select Authorizer_test.
When the gateway service starts, it registers its information with CSE.
It includes at least endpoint (DIS gateway address), region (region where DIS resides), ak (user AK), sk (user SK), projectId (user project ID), and group.id (app name, indicating a consumer group). It can also include auto.offset.reset.
Connection Addresses Connection addresses of the instance: ROMA Connect LINK APIC APIC (Private): used for backend and gateway components.
Ensure that the following network requirements are met: The source server can connect to the Huawei Cloud API Gateway over TCP port 443. For more information, see Connecting Source Servers to Huawei Cloud API Gateway.

On the configuration page that is displayed, set Program arguments in the following format:DIS gateway address + Region name + AK + SK + Project ID + Stream name https://dis.
- endpoint Yes DIS gateway address.
Advantages of GaussDB(DWS) are as follows: Real-time archiving of stream data: importing stream data from IoT devices and the gateway to GaussDB(DWS) using HUAWEI CLOUD DIS Device monitoring and prediction: device monitoring, control, optimization, supply, self-diagnosis
The edge gateway reports data to the IoTDA through MQTT. IoTDA can directly push data to customers' applications and allow applications to deliver commands to control the start and stop of the charging.
