You can integrate a BlackBerry® Enterprise Server with your organization's existing infrastructure which might include messaging and collaboration components, calendar and contact information, wireless Internet and intranet access, and third-party applications to provide BlackBerry device users with mobile access to your organization's resources.

When you configure Hosted BlackBerry® services, you must install the BlackBerry Enterprise Server in the data center that the messaging server is located in to optimize the performance of the BlackBerry Enterprise Server. The BlackBerry Enterprise Server and messaging servers can host messaging and application components for one or more customers.

To configure Hosted BlackBerry services, you must purchase a BlackBerry® Client Access License for the BlackBerry Enterprise Server that permits you to use Hosted BlackBerry services.

For information about the hardware that you require to run a BlackBerry Enterprise Server with Hosted BlackBerry services, see the BlackBerry Enterprise Server Capacity Calculator.
