Architecture: High availability for
BlackBerry UEM

The following diagram shows a high availability domain with two
BlackBerry UEM
instances. You can install any number of
BlackBerry UEM
instances. This topic explains how specific components are involved in a high availability configuration. For more information about the
BlackBerry UEM
architecture and components, see the Architecture content.

Components
Description
BlackBerry UEM
database
Each
BlackBerry UEM
instance connects to the
BlackBerry UEM
database to access user and device data.
Management console and
BlackBerry UEM Core
You can use any management console to manage the domain’s user accounts and devices. The
BlackBerry UEM Core
associated with that console carries out the management tasks.
You can configure a round-robin DNS pool that connects to each console. If there is a problem with a console, the pool connects to a working console.
Each instance manages enterprise connectivity for the
BlackBerry 10
devices that are assigned to it by the
BlackBerry Affinity Manager
. Any healthy instance can process device management tasks for all device types.
BlackBerry MDS Connection Service
and
BlackBerry Dispatcher
These components allow
BlackBerry 10
devices to connect to and use work resources.
BlackBerry Affinity Manager
The
BlackBerry Affinity Manager
is responsible for:
  • Assigning
    BlackBerry 10
    devices to
    BlackBerry UEM
    instances
  • Maintaining a connection with the
    BlackBerry Infrastructure
  • Checking the health of the
    BlackBerry MDS Connection Service
    and
    BlackBerry Dispatcher
    in each instance to monitor enterprise connectivity
Only one
BlackBerry Affinity Manager
is active (the others are on standby). If the active instance finds a problem with enterprise connectivity, it reassigns
BlackBerry 10
users to the healthy
BlackBerry UEM
instances.
Each standby
BlackBerry Affinity Manager
monitors the active
BlackBerry Affinity Manager
. If there is a problem with the active
BlackBerry Affinity Manager
, a failover occurs and one of the standby instances becomes active.
