Amazon Linux vs Rocky Linux

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.

Rocky Linux is a free, open-source enterprise operating system designed for bug-for-bug compatibility with Red Hat Enterprise Linux. It rebuilds sources directly from Red Hat Enterprise Linux and supports migration from other Enterprise Linux distributions. The project describes it as production ready and gives major releases a 10-year support lifecycle: five years of active support followed by five years of security support. Only the latest minor release is supported. Images are available for physical installation, cloud platforms, containers, and Windows Subsystem for Linux, among other formats. Rocky Linux 10 supports x86-64-v3, riscv64, aarch64, ppc64le, and s390x, though architecture support varies by release. It uses DNF for package management and upgrade commands, with RPM packages in a RHEL-compatible software environment. Rocky Linux 10 requires x86-64-v3 on x86_64 and omits 32-bit compatibility packages. Major-version upgrades are not supported, so moving to Rocky Linux 10 requires a fresh installation. Community and commercial support options are listed.
