AlmaLinux OS vs Amazon Linux

AlmaLinux OS is a free, open-source, community-owned enterprise Linux distribution designed for binary compatibility with RHEL. The project presents it as an option for users who need enterprise Linux without a commercial license agreement, including people seeking a CentOS Linux replacement. It can run on servers, workstations, virtual machines, cloud instances, containers, Raspberry Pi devices and Windows Subsystem for Linux environments. ISO downloads cover x86_64, aarch64, ppc64le and s390x architectures. The project also provides cloud images, OCI, Docker and UBI-compatible container images, Vagrant images, and live media with several desktop choices. A WSL image provides a terminal environment on Windows. The Foundation publishes security and bug-fix errata, and packages are GPG-signed and verified by default when installed. OpenSCAP, SCAP Workbench, OVAL streams and CIS tooling are available for auditing or hardening systems. Community support is available through forums, chat and Reddit; commercial support is offered separately by listed providers. The project plans stable updates and security patches for 8.x until 2029 and 9.x until 2032.

Amazon Linux is AWS’s portfolio of Linux-based operating systems for EC2 instances and Docker container workloads. Amazon Linux 2023 is an RPM-based general-purpose distribution designed for AWS integration and cloud scale. It is optimized for EC2 and works with Systems Manager and the AWS CLI. Versioned repositories lock machine images and container images to a package state while letting customers choose when to update. AWS provides an EC2 image launchable from the console, SDK or CLI, plus container images usable outside AWS, including local development. The distribution supports x86-64 and 64-bit ARM architectures, including Graviton2 or later on EC2, and uses DNF. AL2023 offers configurable SELinux and cryptographic policies, kernel live patching, and five years of support through June 2029. Amazon Linux 2027 is available as a public preview for non-production testing, with separate support limits.
