Dimensions summary
You pay by the hour based on the EC2 instance type you choose to run Chariot MQTT Server. Each dimension maps to a specific AWS instance size, from small general-purpose types like t2.nano and t3.micro up to memory-, compute-, storage-, and accelerator-optimized types and large bare-metal servers. Pricing scales with the compute, memory, and hardware capacity of the instance. You select one instance that fits your workload, and you are billed only for the hours it runs. Larger or specialized instances carry higher hourly rates than smaller ones.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the type you select. You are billed for every hour that instance runs. The software supports unlimited MQTT clients and Edge Nodes, so client count does not add to the bill. Only the instance-hours you run determine your charges.
Hourly software charges apply only while the instance runs. A fully stopped instance does not accrue hourly software fees. You may still pay underlying AWS storage costs for the attached volume. To avoid software charges during idle periods, stop the instance when it is not needed.
No. Client and tag count do not appear as billing dimensions. Chariot supports unlimited MQTT clients and Edge Nodes with no sizing restraints. Your cost is driven only by the instance type you run and the hours it runs. To handle more traffic, you choose a larger instance.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
