Amazon Linux 2027 (AL2027) entered public preview as the successor to AL2023, designed specifically for cloud-native applications on AWS. Key improvements include enforcing SELinux by default, upgrading to kernel 7.1+, and enhancing cryptographic performance with AWS-LC. It also ships with updated language runtimes and toolchains catering especially to AI/ML, with accelerated support for AWS Neuron drivers.
The preview provides both x86-64 and ARM AMIs across commercial AWS regions and container base images via Amazon ECR Public Gallery. Customers can test new features and provide feedback through GitHub ahead of general availability. AL2027 targets users operating web apps, databases, microservices, and large-scale infrastructure seeking a secure, performant AWS-native OS.
