Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time. Alternatively, you can pay upfront for a contract, which typically covers your anticipated usage for the contract duration. Any usage beyond contract will incur additional usage-based costs.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
You pay by the hour for a hardened CentOS Stream 9 operating system image built for ARM-based processors. Pricing is not tiered. Instead, each dimension maps to a specific AWS EC2 instance type, and your rate follows the instance you run. Costs scale with the size and family you pick. Larger instances (such as 48xlarge and metal options) carry higher hourly rates than smaller ones (such as medium or large). You choose the instance that fits your compute, memory, or storage needs. Billing continues for each hour the instance runs. The software cost is separate from AWS infrastructure charges.
Top-of-mind questions for buyers
One unit is one running EC2 instance measured per hour. Each instance you launch with this image accrues its own hourly software charge. The rate follows the instance type you select. Running multiple instances means each one bills separately for every hour it runs.
The software fee meters running hours only. A stopped or paused instance does not accrue this hourly software charge. However, AWS may still bill you separately for underlying storage or other infrastructure while the instance is stopped. Those AWS charges are separate from the software cost.
The image provides a hardened CentOS Stream 9 operating system baseline verified against PCI DSS 4.0.1 at the packaged release. Your applications, cloud account configuration, and any changes made after deployment fall outside this image-level scope and remain your responsibility.

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.
