Dimensions summary
You pay by the hour for the software running on your chosen AWS EC2 instance. Each dimension maps to a specific instance type, so pricing scales with the size and family of the machine you select. Smaller instances cost less per hour, while larger and specialized instances (compute, memory, storage, or GPU/accelerator families) cost more. There are no tiers or upfront commitments here. You simply pick the instance that fits your workload, and the hourly rate reflects that instance's compute capacity. This listing delivers a hardened Ubuntu 20.04 image maintained by the vendor's security team.
Top-of-mind questions for buyers
Each hourly rate covers the hardened Ubuntu 20.04 software running on one AWS EC2 instance of the type you pick. You pay separately for the underlying AWS compute. One instance running for one hour equals one billable hour, so charges scale with how many instances you run and for how long.
The software fee meters running time only. A stopped or powered-off instance does not accrue the hourly software charge. AWS may still bill you for attached storage on a stopped instance, but that is separate from the software rate shown for each instance type.
This image ships hardened using NIST and DevSec frameworks, with over 100 security controls enabled. The vendor's security team maintains and updates it monthly. You get support included. It is built for secure environments and can launch across many instance families in minutes.

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.
