Planning high availability for a
BlackBerry UEM
domain

BlackBerry UEM
uses an active-active high availability model to minimize service interruptions for device users. To configure high availability, you install multiple instances of
BlackBerry UEM
, each on a separate computer. Each instance connects to the
BlackBerry UEM
database and actively manages user accounts and devices.
High availability in
BlackBerry UEM
includes the following features:
Feature
Description
iOS
,
Android
, and
Windows
devices can connect to any
BlackBerry UEM
instance
iOS
,
Android
, and
Windows
devices can connect to any
BlackBerry UEM Core
instance to receive device management, policy, and configuration updates. If one or more
BlackBerry UEM Core
instances is unhealthy,
iOS
,
Android
, and
Windows
devices connect to one of the healthy instances. Load balancing is performed automatically. As a result, device management services continue uninterrupted.
Access the management console and
BlackBerry UEM Self-Service
from any
BlackBerry UEM
instance
If there is a problem with the management console or
BlackBerry UEM Core
for a
BlackBerry UEM
instance, you can continue to access the management console and the
BlackBerry UEM Core
of any healthy instance.
Round-robin DNS pool for the management console
You can use third-party software to configure a round-robin DNS pool that connects to the management console in each
BlackBerry UEM
instance. If there is a problem with a console, the pool makes sure that you connect to a working console.
Round-robin DNS pool for the web services API
You can use third-party software to configure a round-robin DNS pool that connects to the web services API in each
BlackBerry UEM
instance. If there is a problem with one web services API, using the pool makes sure that you connect to a working web services API. If there is a problem using the web services API pool, check the round robin mechanism to ensure the web services API is correctly connected. 
BlackBerry Connectivity Node
You can install one or more instances of the
BlackBerry Connectivity Node
to add additional instances of the device connectivity components to your organization’s domain. You can also create server groups to specify regional data paths for secure connectivity and to set up high availability for the components of the
BlackBerry Connectivity Node
. For more information, see High availability and the BlackBerry Connectivity Node.
When
BlackBerry UEM
is completing a recovery action, affected users experience a short service interruption.
