Create Serverless Deployment
EMQX Cloud Serverless Plan offers a cost-effective and efficient way for developers or small businesses to test and develop IoT applications. This plan is based on secure and scalable clusters and can be easily deployed in just a few simple steps.
One of the biggest advantages of using Serverless deployment is that the billing for connection scenarios is based on actual usage. For more detailed information on the billing system, please refer to the pricing section in Pricing and Billing.
Log in to EMQX Cloud console.
You can create a new deployment for a specific project from either the Console homepage or the deployment list page. Click + New.
Click Start for free on the Serverless tab.
In the New Deployment page, you can set the monthly Spend Limit for your Serverless deployment to control usage and avoid unexpected charges beyond the free resources. It's initially set to 0, but can be modified after creation. Then click Deploy at the page bottom to start the process.
- As part of the deployment process, you'll be asked to agree to the EMQX Cloud Services Agreement, please review the agreement carefully and accept it if you agree with its terms.
- After agreeing to the agreement, the deployment process will begin. You can monitor the progress on the Projects page, and once the status changes to Running, your deployment has been successfully created and is ready for use.
After the deployment is created, it will appear on the Cloud console home page. Click the Serverless deployment card to enter the deployment overview page. On the overview page, you can check the real-time status and connection information for your deployment.
- Instance status: Running status and duration of operation.
- Sessions: Current and maximum connection counts.
- Pub&Sub TPS: Current messages sent and received per second, as well as the TPS limit.

Test Connection for the Deployment
EMQX Cloud recommends using MQTTX to test the connection to the deployment, but you can also use your preferred SDK or other tools to connect to it. Before connecting to the deployment using MQTTX, you first need to obtain the deployment connection address (Host) and port (Port) and also use a user for authentication.
- The deployment will be stopped if there are no active client connections for 30 consecutive days. To continue using it, please manually enable it in the console.
- If the deployment remains inactive for 30 days after being stopped, it would be deleted.
Get the connection information. Click Overview on the left navigation menu to find the deployment connection address and port.
Add client authentication information. Go to the deployment overview page, and click Authentication & ACL -> Authentication. Then, click on the Add button, enter the username and password for the client or device, and click Confirm.
Now you can set up the connection information in MQTTX as follows and start to test the connection.
After the connection succeeds, you can try to subscribe and publish.
