Default roles

While installing ConfigMgr server or any of its particular roles, the default roles--mandatory for the environment--are installed. This is the list of default ConfigMgr server roles:

• Site server: This provides fundamental functionalities for the ConfigMgr server.
• Site system: This is the server that provides specific ConfigMgr functionalities. The role is automatically installed while installing some of the optional roles or when installing the ConfigMgr role.
• Component system: This is the server that runs the SMS Executive service, which means the server holds a site system role.
• Site database server: This is the role installed on a server that holds the SQL installed for the ConfigMgr server.
• SMS Provider: This is the role installed with the ConfigMgr server, and it enables communication between the server and the SQL database.

These roles are installed with some default settings, and the administrator has limited options for adjusting this setting. All other roles are optional ones, which means the administrator can install them on any system.
