Amazon Linux review
A free, AWS-focused Linux distribution with controlled updates and EC2 and container images.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Amazon Linux 2023 (AL2023) is a general-purpose, RPM-based Linux distribution designed for workloads on AWS. It suits teams running Amazon EC2 instances or Docker container workloads, including local development, who want an operating system that fits AWS services and tools. AWS provides it without an additional operating-system charge; EC2 and other AWS services are charged separately.
Deployment and ecosystem fit are its clearest strengths. AWS distributes AL2023 as Amazon Machine Images for launching EC2 instances and as a Docker-compatible container image available from Amazon ECR Public. The image can also be used outside AWS, including locally. Integrations include Amazon EC2, Amazon ECS, Amazon ECR, AWS CLI and AWS Systems Manager. That makes it a natural choice for AWS-centered deployments, but less compelling where workloads need a broadly neutral operating-system choice across heterogeneous infrastructure.
For package control, AL2023 uses DNF and versioned repositories to support deterministic updates. Quarterly minor releases bring security updates, bug fixes and new features. AWS states that AL2023 is supported until June 30, 2029, with standard support through June 30, 2027, followed by maintenance support; individual LTS kernels are supported for four years. FIPS mode and validated cryptographic modules are also included. Systems Manager can manage fleet kernel updates. Choose AL2023 for AWS-native EC2 and container environments that value this release and management model. Organizations running its images outside AWS should account for the fact that AWS Support Plans do not cover them; teams prioritizing heterogeneous infrastructure may prefer a distribution suited to that broader environment.
Amazon Linux pros and cons
- Where it wins
- Free to run, with EC2 AMIs and Docker-compatible container images
- Versioned repositories support deterministic package updates
- Systems Manager supports fleet kernel update management
- Where it doesn't
- Its strongest fit is AWS, not heterogeneous infrastructure
- AWS Support Plans do not cover AL2023 images used outside AWS
- EC2 and other AWS services still incur charges
