You can install one or more instances of the BlackBerry Connectivity Node to add additional capacity for device connectivity, for the purposes of regionalizing device connectivity, or for the purpose of high availability or disaster recovery.

Each BlackBerry Connectivity Node instance contains the following BlackBerry UEM components:

• BlackBerry Secure Connect Plus
• BlackBerry Gatekeeping Service
• BlackBerry Secure Gateway
• BlackBerry Proxy
• BlackBerry Cloud Connector

Each BlackBerry Connectivity Node instance provides another active instance of these components to the BlackBerry UEM domain that can process and manage secure device connections (by default, the BlackBerry Gatekeeping Service in a BlackBerry Connectivity Node instance is disabled).

Enterprise connectivity can be maintained by creating server groups for BlackBerry Secure Connect Plus connectivity or BlackBerry Proxy clusters for BlackBerry Dynamics connectivity.

A server group contains one or more instances of the BlackBerry Connectivity Node. When you create a server group, you specify the regional data path that you want the components to use to connect to the BlackBerry Infrastructure. You can associate email and enterprise connectivity profiles with a server group. Any device that is assigned those profiles uses that server group’s regional connection to the BlackBerry Infrastructure when it uses any of the components of the BlackBerry Connectivity Node.

Optionally, you can designate each BlackBerry Connectivity Node in a server group to handle a single connection type: BlackBerry Secure Connect Plus only, BlackBerry Secure Gateway only, or BlackBerry Proxy only. This frees up server resources to allow fewer servers required for the same number of users or containers.

A BlackBerry Proxy cluster contains one or more instances of the BlackBerry Connectivity Node. When you create a BlackBerry Proxy cluster, you specify the BlackBerry Proxy servers included in the cluster, as well as whether that cluster will be used for BlackBerry Dynamics activation, or only for application server connectivity.

After you install a BlackBerry Connectivity Node, you must register it before it can be used.
