AlmaLinux OS Kitten 10 is free software. You pay no charge for the operating system itself on AWS Marketplace. Pricing is organized by EC2 instance type, billed per hour. Each dimension maps to one AWS instance size, from small general-purpose types to large compute, memory, storage, and accelerated options. Your hourly cost reflects the AWS infrastructure you select, not the software. You scale by choosing a larger or different instance type to match your workload. The operating system remains free across every instance choice.
Top-of-mind questions for buyers
What am I actually paying for when the operating system itself is free?
You pay only for the AWS EC2 instance you run, billed per hour. AlmaLinux OS Kitten 10 adds no software charge on any instance type. Your hourly cost reflects the compute, memory, storage, or accelerated instance you select to match your workload.
Am I charged for the software when an instance is stopped or paused?
The software carries no charge in any state, since AlmaLinux OS Kitten 10 is free. When an instance is stopped, you stop paying the per-hour instance rate. Underlying AWS storage fees for attached volumes may still apply while the instance is stopped.
How do I change cost if my workload grows or shrinks?
You choose a different EC2 instance type to scale. A larger instance raises your hourly rate; a smaller one lowers it. Each dimension maps to one instance size across general-purpose, compute, memory, storage, and accelerated families. The operating system stays free at every size.
