AlmaLinux OS 9 (x86_64) carries no software charge. The operating system itself is free, so every pricing dimension here reflects the AWS EC2 instance you choose to run it on, billed by the hour. Each dimension maps to a specific instance type and size, from small general-purpose options to large compute, memory, and metal configurations. You pick the instance that fits your workload, and your hourly cost scales with that instance's capacity. There are no tiers or add-ons for the software layer — you pay only for underlying AWS compute.
Top-of-mind questions for buyers
What do I actually pay for when the AlmaLinux OS software itself is free?
You pay only for the AWS EC2 instance you run. Each dimension maps to an instance type and size, billed per hour. The AlmaLinux OS license adds no software charge, so your invoice reflects underlying AWS compute alone.
Am I charged when my instance is stopped or powered off?
The software carries no charge whether the instance runs or not. Hourly costs reflect AWS EC2 running time, so a fully stopped instance stops accruing compute charges. Stopped instances may still incur AWS storage fees for attached volumes, which are separate from this listing.
Why are there so many pricing lines, and how do I pick one?
Each line maps to one EC2 instance type and size, from small general-purpose to large compute, memory, and metal configurations. You choose the instance matching your workload. Your hourly cost scales with that instance's capacity. Larger instances cost more per hour; the software rate stays free across all.
