The AlmaLinux OS 9 (x86_64) software itself is free of charge. You pay by the hour, and the only variable is which Amazon EC2 instance type you run. Each dimension maps to one instance type, grouped into families such as general purpose, compute, memory, storage, and accelerated computing. Pricing scales with the instance you select, from small shared-core sizes up to bare-metal and multi-GPU configurations. Larger instances within a family carry higher hourly rates. You choose the instance that fits your workload, and billing follows its running hours.
Top-of-mind questions for buyers
What does the hourly rate on each dimension actually cover for AlmaLinux OS 9?
The AlmaLinux OS 9 software itself carries no charge. Each hourly rate reflects running one specific Amazon EC2 instance type. You pay for the instance hours while the machine runs. The operating system is free of charge across every deployment channel, so your bill tracks compute size and running time only.
Am I charged for the software while an instance is stopped?
The AlmaLinux OS 9 software is free, so no software charge applies whether the instance runs or is stopped. Hourly billing reflects the instance type you run. A stopped instance stops accruing instance-hour charges, though underlying AWS storage for the volume may still apply through your AWS account.
Why are there so many dimensions, and how do I pick the right one?
Each dimension maps to one Amazon EC2 instance type. They span families such as general purpose, compute, memory, storage, and accelerated computing. You pick the single instance that matches your workload size and needs. Billing then follows that instance's running hours. Larger instances within a family carry higher hourly rates.
