# Configure environments

Environment-level configuration: settings that differ between Dev, Stage, and Prod, and jobs that run on a schedule. Start with [scheduled jobs](/cloud-platform/configure/cron/).

[Acquia Search](/start-here/glossary/#acquia-search) is configured per environment too, each environment pointed at its own index so non-production writes never reach production's. [Acquia Search powered by SearchStax](https://docs.acquia.com/acquia-cloud-platform/acquia-search-powered-searchstax) covers the current service and its onboarding, and [managing search indexes](https://docs.acquia.com/acquia-cloud-platform/managing-search-indexes) covers index administration on both generations.

- [Run scheduled jobs](/cloud-platform/configure/cron/): Background work on Cloud Platform. Scheduled jobs per environment, running Drupal cron via drush the reliable way, and keeping job output out of trouble.
- [Per-environment settings](/cloud-platform/configure/settings/): The three configuration surfaces you control per Cloud Platform environment. Platform environment variables, tunable PHP settings, and settings.php overrides.
