AlmaLinux OS Kitten 10 is the direct upstream for AlmaLinux OS 10 and is the primary point for the AlmaLinux community to engage and influence the future of AlmaLinux OS. Fixes and features land here first and trickle down into AlmaLinux OS as appropriate. It is the integration and collaboration point for AlmaLinux to its upstreams as well, such as CentOS Stream and Fedora.

The software itself is free. You pay only the hourly rate for the AWS EC2 instance you run it on. Pricing scales by instance type, so each listed dimension maps to one EC2 size. General-purpose, compute-optimized, memory-optimized, storage-optimized, accelerated-computing, and high-performance families all appear. Rates rise as an instance adds vCPUs, memory, or specialized hardware. Smaller sizes bill less per hour; larger and bare-metal sizes bill more. You choose the instance that fits your workload and are charged by the hour for however long it runs.
Top-of-mind questions for buyers
What am I actually paying for, since the AlmaLinux software is free?
The operating system carries no software charge on any instance. You pay only the AWS EC2 compute rate for the instance type you launch. Each listed dimension matches one EC2 size and bills by the hour for the time it runs.
Am I charged when my instance is stopped or powered off?
The operating system is free of charge regardless of state, so no software fee applies. Hourly EC2 compute charges stop accruing when the instance is stopped. Attached storage may still incur separate AWS storage fees while the instance is not running.
How does cost change when I move to a larger instance type?
Each dimension maps to one EC2 size, billed per hour. Moving up adds vCPUs, memory, or specialized hardware, so the hourly rate rises. Bare-metal and the largest sizes bill the most per hour. You pick the size that fits your workload.
