You pay nothing for the Rocky Linux 8 software itself; it is free and open source. Your only charges come from the AWS EC2 instance you run it on, billed hourly. Each dimension maps to a specific EC2 instance type, such as general-purpose, compute-optimized, memory-optimized, storage-optimized, and accelerated-computing families. Your cost scales with the instance you choose. Larger sizes within a family carry higher hourly rates than smaller sizes. Pick the instance type that matches your workload's compute, memory, or hardware needs. There are no tiers or commitments tied to the software.
Top-of-mind questions for buyers
What does one hour of billing cover for a given instance type?
You are billed per running hour of the EC2 instance you select. Each dimension maps to one specific instance type, defining its CPU, memory, and hardware. The Rocky Linux 8 software adds no charge. You pay only the hourly rate tied to that instance type while it runs.
Am I charged when the instance is stopped or powered off?
Hourly software charges apply only while the instance runs. A fully stopped instance stops accruing hourly charges. Since Rocky Linux 8 software is free, you would incur no software fee regardless. You may still pay AWS for attached storage, such as EBS volumes, while the instance is stopped.
Can I move an existing Enterprise Linux server to Rocky Linux 8 without added software cost?
Yes. Rocky Linux provides a free migration script to convert other Enterprise Linux distributions. The software carries no license fee. On AWS you pay only for the EC2 instance hours of whatever instance type you run. No commitment or software tier is tied to migration.

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.

This is a repackaged open source software product wherein additional charges apply for support provided by Fifty Clouds. Rocky Linux 8, supported by Fifty Clouds, is a robust, open-source enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux (RHEL). Developed by the Rocky Linux community and sponsored by the Rocky Enterprise Software Foundation, this distribution offers enterprise-level stability, security, and performance.
This Rocky Linux 8 image has charges associated with it for seller support and maintenance. Rocky Linux 8 delivers a stable, secure, and fully open-source foundation for modern cloud workloads on AWS EC2. This Rocky Linux 8 AMI enables fast deployment, seamless updates through official Rocky Linux 8 repositories, and full cloud-init support for automation. With ENA networking, SELinux enforcement, and enterprise-grade compatibility with RHEL 8, Rocky8 provides predictable performance for web servers, databases, and CI/CD pipelines. Built, tested, and continuously maintained by ProComputers, this Rocky Linux 8 image is production-ready and optimized for scalability, reliability, and long-term operations in the AWS Cloud.
Overall, this is a perfectly serviceable RHEL clone offering. Currently, only real complaints are:
* No Compliance as Code project-entries, so that tool can't be used to automate security-hardening to desired hardening-benchmarks (PCI/DSS, CIS, STIG, etc.) * Can't use CSP's automated tasks due to service-document issues – even though it's a RHEL clone, services like SSM and GuardDuty don't quite know what to do with/for it

Rocky 8 Available for Amazon EC2 G6 Instances?
Reviewed on May 28, 2024
Review from a verified AWS customer
When is the EC2 G6 instance going to be available for Rocky 8? We have an HPC environment and require the new EC2 G6 instances to be available with the Rocky 8 OS. Is this possible?

I used this to replace my CentOS environment. If you're thinking of migrating from RHEL or CentOS, Rocky Linux is a great replacement.

Why is the smallest instance type a t3a.small!?
Reviewed on Jan 05, 2023
Review from a verified AWS customer
This AMI does not support the smaller instance types that a large amount of people use. I know Rocky Linux 8 technically supports it because they are available in the Community AMI section but the Marketplace is the only place I really trust to deploy AMI's from using official AMI's from Rocky Linux themselves. This is a big disappointment and we are meeting as a company about this now and whether we want to adopt Rocky Linux or Alma/Amazon Linux instead.
This AMI only supports a t3a.small at $0.019/hr which is 3-4x the price of the smallest instance types that CentOS 8, RHEL 8, Alma and others support. Rocky Linux team please get this addressed or reply with the reasoning
