To connect your application to the EMQX Cloud, you need to create and configure a deployment.

Serverless Deployment

1. Create a Serverless deployment in the EMQX Cloud Console.

2. Once the deployment is created and running, go to the deployment Overview page to find the MQTT connection information, including:

   • Broker address

   • Port number (only TLS ports are supported in Serverless)

3. Serverless deployments require TLS connections. Make sure to download the CA certificate from the Overview page and use port 8883 for TLS.

4. Configure the default authentication (username/password) under Access Control -> Client Authentication in the deployment.

For more details, refer to the Serverless Port Guide.

Dedicated Flex or BYOC Deployment

1. You can create a Dedicated Flex or BYOC deployment in the EMQX Cloud Console.
2. After creation, go to the deployment Overview page to retrieve MQTT connection information, including:
   • Broker address
   • TCP and TLS port numbers for MQTT and WebSocket (Both TCP and TLS connections are supported).
3. Configure the default authentication (username/password) under Access Control -> Client Authentication in the deployment.

For detailed port configurations, see the Dedicated & BYOC Port Guide.
