WordPress Cron and Server Cron are two different methods of scheduling, executing tasks, and data import export actions in the context of WordPress websites.
WordPress Cron
WordPress Cron is a cron system implemented within the WordPress ecosystem itself. It allows you to schedule and run tasks within the WordPress environment, such as data import export, publishing scheduled posts, checking for updates, performing various maintenance tasks, etc.
WordPress Cron is driven by website traffic. This means that the execution of WordPress Cron jobs depends on the incoming traffic to your website. If there is no traffic, the tasks might not be executed on time.
WordPress Cron makes it easy to schedule tasks without having to rely on server-level cron jobs. It simplifies the process for non-technical users and allows them to manage scheduled events directly from the WordPress dashboard or through plugins.
Server Cron
Server Cron is a time-based job scheduler at the server level. The scheduler operates outside the WordPress environment and is not dependent on visitor traffic. You can configure server Cron to run scripts, commands, or programs at predefined intervals, regardless of website traffic.
Server Cron provides more control and reliability compared to WordPress Cron because it is not dependent on website traffic. Server Cron jobs are typically controlled by the server’s command line or a control panel provided by the hosting provider. You can set up a server Cron to trigger WordPress-specific tasks or any other system-level tasks.
In summary, WordPress Cron is easy and requires less technical effort as it is an internal scheduling mechanism within WordPress, dependent on visitor traffic, while server Cron is a system-level scheduler that operates independently of WordPress and website traffic.
Server Cron offers enhanced control and reliability, making it ideal for executing critical tasks or those that demand precise timing.
