Dimensions summary
You pay by the hour based on the AWS EC2 instance you run this load balancer on. Pricing is not tiered by features. Instead, each dimension maps to a specific instance type across the m5, c5, and r5 families, plus their local-storage d variants. Larger instance sizes carry more compute, memory, or storage, so cost scales with the instance you select. There is no upfront commitment. Billing follows actual hourly usage, which suits variable or seasonal traffic. The MAX edition provides uncapped throughput, so you size capacity by choosing the instance rather than a throughput plan.
Top-of-mind questions for buyers
Each dimension maps to one running AWS EC2 instance of a specific type, such as m5.large or c5.9xlarge. You are billed per hour that instance runs. The instance family and size set the compute, memory, and storage available to the load balancer software.
The software charge is metered hourly against running instance time. Stopped or powered-off instances do not accrue software charges. AWS may still bill underlying storage for stopped instances, but the load balancer software meters running hours only. This suits seasonal or bursty demand.
Hourly billing meters actual instance-hours with no upfront commitment on consumption. You are billed only for the hours each instance runs, directly through the cloud provider, with support included. This model fits workloads with variable or seasonal traffic that need extra capacity for limited periods.

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.
