Create a Serverless Deployment
EMQX 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 it is billed based on actual usage. For more detailed information on the billing system, see the Pricing section in Pricing and Billing.
Create a Deployment
Log in to the EMQX Platform console.
To initiate a new deployment for your project, navigate to either the Console's homepage or the Deployment List page. Here, click + New Deployment.
In Choose Plan, select Serverless.
Specify the monthly Spend Limit for your Serverless deployment. This feature helps manage usage and prevent incurring charges beyond the complimentary resources. By default, it is set to 0 but can be adjusted after creation.
Under Deployment Name & Project, provide a name for your deployment and select the appropriate project.
Click the Deploy button on the right to launch the deployment. This stage will prompt you to review and accept the EMQX Platform Services Agreement. It's important to thoroughly read the agreement and accept its terms to proceed.
Upon accepting the terms, the deployment will begin. The deployment's progress can be tracked on the Projects page. Once the status updates to Running, your deployment is successfully established and is now operational.
