Overall, the public cloud runs on Linux. Most users, even Microsoft Azure customers, are running Linux in the cloud.
In the case of market giant Amazon Web Services (AWS), the cloud provider will let you run many Linux distributions or their own Linux homebrew, Amazon Linux. Now AWS has released a first version of its upcoming distro, Amazon Linux 3, which is based on Red Hat’s Linux community, Fedora.
AWS has long tried to bring Red Hat Enterprise Linux (RHEL) compatibility into Amazon Linux, but this latest release takes it to new heights. Using Fedora upstream, the new Amazon distribution, also known as AL2022, is a stable distribution. It has been extensively tested to provide package stability, and it also includes all available security updates. It is, of course, optimized for Amazon EC2, is integrated with the latest AWS features, and includes an integrated experience with many AWS-specific tools.
This new Amazon Linux also provides frequent and flexible quarterly updates. For example, each AL2022 update locks to a specific version of the Amazon Linux package repository. You only need to update when you want to take a step, not when a new version is released.

To improve its overall security, AL2022 comes with SELinux enabled and applied by default. SELinux’s core security approach, which restricts everything except explicit permission, is the opposite of Linux’s default security policy, allowing everything except explicit prohibition. But when properly deployed, SELinux dramatically improves your security. By setting it up from the start, AL2022 will help you lock down the security of your instances before attackers can target you.
AL2022 is now available in preview in all commercial regions. You can launch AL2022 from the AWS Management Console, AWS Command Line Interface (CLI), AWS Tools for Windows PowerShell, RunInstances, or through an AWS CloudFormation template.
This distribution is released on a two-year release cycle and will also be supported for five years. So if you standardize on AL2022, you will be supported until 2027.
There is no charge for AL2022, however, standard Amazon EC2 and AWS charges apply for running its Amazon EC2 instances and other related services.
