Kentico CMS allows you to manage multiple sites in a single installation. The database contains data for all websites and the websites are managed using a single administration interface (single copy of code). The following figure shows the multi-site configuration where one database and one copy of CMS code are used for multiple websites.

When you use multi-site configuration, you can share:
| • | documents | 
| • | users | 
| • | global settings and system tables | 
| • | document types | 
| • | page templates |
