Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Deprecated in AL2027

Functionality deprecated in AL2027 is likely to be removed in a future version of Amazon Linux. Moving off deprecated functionality now reduces the work of migrating to the next version. This section is updated over the lifetime of AL2027 as the Linux ecosystem evolves.

cron

The cronie package remains available in the AL2027 repositories, and remains deprecated, as in AL2023. You can install it to run classic cron jobs, but we recommend migrating to systemd timers. A future version of Amazon Linux might not include support for classic cron jobs.

IMDSv1

As with AL2023, AL2027 AMIs are registered so that instances launch in IMDSv2-only mode by default, disabling IMDSv1. The option to enable IMDSv1 on an instance still exists. A future version of Amazon Linux is likely to enforce IMDSv2-only.

For more information on IMDS configuration for AMIs, see Configure the AMI in the Amazon EC2 User Guide.

aspell

The aspell package is deprecated in AL2027. Use hunspell or enchant2 instead. A future version of Amazon Linux might not include aspell.

EOL packages are deprecated

Each package in AL2027 has an associated support timeline, which you can query with the dnf supportinfo command. For more information, see Getting package support information. Where a package's support ends before the end of the major version of Amazon Linux, assume that the package is deprecated and will not be present in the next major version of Amazon Linux.
