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).

systemd timers replace cron

The cronie package was installed by default on the AL2 AMI, providing support for the traditional crontab way of scheduling periodic tasks. In AL2023, cronie is not included by default. Therefore, support for crontab is no longer provided by default.

You can optionally install the cronie package to use classic cron jobs. We recommend that you migrate to systemd timers due to the added functionality provided by systemd.
