AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
AlmaLinux OS 9 (arm64) is free software, so the operating system itself carries no license charge. You pay only for the AWS EC2 compute you run it on, billed hourly per instance. The pricing dimensions are arm64 (Graviton-based) EC2 instance types, grouped into families for general-purpose, compute-optimized, memory-optimized, storage-optimized, high-memory, and HPC workloads. Within each family, hourly rates scale with instance size, from small options up to metal instances. You choose the family and size that fit your workload, then billing follows AWS hourly usage for that instance.
Top-of-mind questions for buyers
What does one hourly instance charge cover for AlmaLinux OS 9 (arm64)?
Each rate covers one running arm64 (Graviton-based) EC2 instance of the chosen type, billed per hour. The AlmaLinux OS software itself is free, so the hourly figure reflects only AWS compute for that instance size. Larger sizes within a family carry higher hourly rates.
Am I charged when an instance is stopped or powered off?
Software charges meter running instance-hours only. A stopped or powered-off instance does not accrue the hourly charge. You may still pay separate AWS fees for attached storage or other resources, but the AlmaLinux OS software is free of charge in all cases.
Does AlmaLinux OS 9 (arm64) include vendor support, or is that separate?
The Marketplace listing bills only for EC2 hours; the OS is free and comes with community support such as forums, chat, and the wiki. Enterprise-grade support is offered separately by third-party providers and is not part of these hourly charges.
