Tell HN: Amazon Linux 2 is EOL today

Amazon Linux 2 reaches end of life (EOL) today, as confirmed by AWS. Users are encouraged to migrate to Amazon Linux 2023 for continued support and security updates.

Background

- Amazon Linux 2 (AL2) is a Linux operating system built by AWS specifically for running applications on its cloud infrastructure. It reached its End of Life (EOL) on June 30, 2025, meaning AWS will no longer provide security patches or updates. - Amazon Linux 2023 (AL2023) is the current replacement — it was released in March 2023 and uses a "rolling update" model (instead of the fixed major-version model of AL2). - Many AWS customers built their applications on AL2; any EC2 instances or Docker containers still running it after EOL are now running unpatched software, which is a security risk. - AWS has provided migration paths (including an automated tool called "Leapp"), but upgrades are not seamless — most teams need to rebuild their AMIs or container images and retest their software.
