Throughout our documentation, we refer to these as \"customer-hosted\" deployments.\n\nWe also offer the option for Looker to host your Looker deployment. Throughout our documentation we refer to these as \"[Looker-hosted](/looker/docs/glossary#looker-hosted)\" deployments. Using a Looker-hosted instance greatly reduces the effort required to [install](/looker/docs/looker-hosted-installation-steps), configure, and maintain the Looker application, because Looker handles all necessary IT functions that are related to the Looker application for you.\n| **Note:** Hosting the Looker application is independent of where your data resides; data always remains in-database and is not copied to the Looker instance. Some Looker features are not available for customer-hosted deployments, or they may require additional configuration or software. To learn more about feature differences between the two hosted options, see the [Choosing a hosting option for a Looker (original) instance](/looker/docs/choosing-hosting-option) documentation page.\n\nComplete the following steps:\n\n1. Install Looker:\n\n - [Add Looker to your server](/looker/docs/installing-looker-application).\n\n - [Configure Looker startup options](/looker/docs/startup-options).\n\n - [Configure your SSL certificate for proper HTTPS](/looker/docs/ssl-certificate-for-proper-https).\n\n - [Consider port forwarding for a cleaner URL](/looker/docs/port-forwarding).\n\n - [Allow Looker support to access your instance](/looker/docs/support-access-customer-hosted-deployment).\n\n - [Set up Looker monitoring](/looker/docs/monitoring-looker).\n\n - [Set up a MySQL backend database](/looker/docs/migrating-looker-backend-db-to-mysql).\n\n | **Note:** We recommend that all new customer-hosted instances set up a MySQL backend database rather than use the default HyperSQL database.\n - [Set up Looker backups](/looker/docs/creating-backups).\n\n - [Ensure that Looker can access necessary services](/looker/docs/outbound-port-requirements).\n\n - [Install rendering software](/looker/docs/installation-of-rendering-software).\n\n - [Determine if your Looker instance can accommodate the Looker Action Hub](/looker/docs/action-hub#considerations_for_customer-hosted_instances).\n\n2. [Enable secure database access](/looker/docs/enabling-secure-db-access).\n\n3. [Configure your database for Looker](/looker/docs/dialects).\n\n4. [Connect Looker to your database](/looker/docs/connecting-to-your-db).\n\n5. [Test your database connectivity](/looker/docs/testing-db-connectivity).\n\n6. [Configure Looker sign-in options](/looker/docs/getting-started-with-users).\n\nOnce your instance is set up, you're ready to [get started with development](/looker/docs/data-modeling).\n\nFeatures that require additional configuration\n----------------------------------------------\n\nThe following Looker features require additional configuration or software to use:"]]
