Dimensions summary
You pay by the hour for this hardened Oracle Linux 8 image, billed per running instance. Pricing has one structure: an hourly software rate tied to the EC2 instance type you choose. Each listed dimension is an AWS instance size, from small general-purpose types to large memory-, compute-, storage-, and GPU-optimized machines. The rate scales with the instance you select, since larger instances carry more vCPU and memory. You add AWS infrastructure charges separately. There are no term commitments; you run instances as needed and stop paying when you shut them down. Vendor support comes with each instance.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the size you select, carrying the hardened Oracle Linux 8 image. You pay the hourly software rate for every instance while it runs. Running ten instances bills ten times the rate. Counting is per instance, per hour.
The software rate meters running time only. When you stop or shut down an instance, the hourly software charge stops. Underlying AWS charges, such as storage for stopped instances, are billed separately by AWS and may still apply even when the software is not running.
The rate is tied to the EC2 instance size you choose. Larger instances carry more vCPU and memory, so they bill a higher hourly rate. Smaller general-purpose types cost less per hour. You pick the instance that fits your workload, and the software rate follows that choice.
