Dimensions summary
You pay by the hour for this hardened Red Hat Enterprise Linux 8 image on ARM64 (Graviton) instances. Each dimension maps to a specific AWS instance type, so your rate reflects the size and family you launch. Options run from small burstable and general-purpose sizes up to large multi-core, memory-optimized, compute-optimized, storage-optimized, and bare-metal instances. Pricing scales with the compute capacity of the instance you choose. This software fee is separate from AWS infrastructure charges. Billing is usage-based, so you pay only for the hours each instance runs.
Top-of-mind questions for buyers
You pay for a hardened, PCI-focused RHEL 8 baseline configured for compliance review. The image ships with a per-image evidence pack as published, monthly patched releases, and a critical-update path. US-based product support is included. Your team still owns application security, cloud architecture, and assessor validation.
The software fee meters running hours. A fully stopped instance does not accrue the hourly software charge. Underlying AWS storage or other infrastructure fees may still apply while the instance is stopped. You pay the software rate only for hours each instance actually runs.
Each dimension maps to one specific ARM64 (Graviton) instance type. Your rate follows the instance family and size you launch, from small burstable types up to large multi-core, memory-optimized, storage-optimized, and bare-metal sizes. Running two instances bills each separately. The software fee is charged apart from AWS infrastructure charges.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
