A streamlined CentOS 9 ARM64 image for AWS Graviton instances, featuring a standardized minimal environment, hardened SSH access, system security settings, persistent logging, Chrony time synchronization, and essential operational defaults.
Overview
This CentOS 9 ARM64 image provides a standardized, security-focused operating system foundation for workloads running on AWS Graviton-based EC2 instances. It is designed for teams that want a clean and consistently configured starting point for application servers, development environments, automation workers, and custom infrastructure deployments.
The image applies a practical set of CIS-inspired system settings, including password complexity and aging policies, inactive-account controls, automatic shell timeouts, restricted sudo behavior with session logging, protected system files, and hardened kernel and network parameters. Unnecessary desktop components, services, Bluetooth packages, and legacy network protocol modules are removed or disabled to reduce system operational footprint.
Remote administration is secured through a hardened OpenSSH configuration. Root login, empty-password authentication, host-based authentication, keyboard-interactive authentication, X11 forwarding, TCP forwarding, and SSH agent forwarding are disabled. SSH connections use an explicitly defined set of modern ciphers, key-exchange algorithms, and message authentication codes. Authentication attempts, concurrent sessions, connection startup rates, and idle connections are also restricted.
For operational reliability, the image includes:
- CentOS 9 optimized for the ARM64 architecture and AWS Graviton instances
- Current operating system packages at image build time
- Chrony-based time synchronization
- UTC timezone and a consistent system locale
- Persistent systemd journal storage
- Rsyslog-based system and authentication logging
- Sudo activity logging and log rotation
- Increased file-descriptor limits for server workloads
- Reverse-path filtering, redirect protection, ASLR, and restricted kernel-pointer access
- A local build-information file for OS, architecture, kernel, image version, and build timestamp identification
Important configuration notes: IPv6, SSH port forwarding, SELinux enforcement, and the auditd package are disabled by this image baseline configuration. Customers should review these settings against their own security, networking, monitoring, and compliance requirements before deploying production workloads. This image is security-focused but is not represented as CIS-certified.
Highlights
- The image intentionally provides a minimal operating system baseline rather than a bundled application stack. Docker and application-specific runtimes are not enabled by default, allowing customers to install and manage only the components required for their workloads.

Dimensions summary
You pay by the hour for each running instance, with no upfront commitment. Pricing attaches to the AWS Arm-based (aarch64) EC2 instance type you choose to run CentOS-9 with Cloudfu support. The listing covers many instance families, including general-purpose, compute-optimized, memory-optimized, storage-optimized, high-performance computing, and graphics types. Within each family, hourly rates scale with instance size, from small shared types up to large and bare-metal configurations. You select the instance type that fits your workload, and billing follows actual usage hours plus standard AWS infrastructure charges.
Top-of-mind questions for buyers
The hourly rate covers the CentOS-9 aarch64 image with Cloudfu support. This includes regular patches, updates, and 7x24 technical support. The software charge is separate from the standard AWS infrastructure cost for the instance you run.
The software charge meters running instance-hours only. A fully stopped instance does not accrue the hourly software fee. Stopped instances may still incur underlying AWS storage charges, but those are separate from this listing's software metering.
You pay one hourly software rate tied to the specific Arm-based EC2 instance type you launch. Larger sizes within a family carry higher hourly rates. The software charge and the AWS infrastructure charge bill together based on actual usage hours.

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.
