The optional High Availability extension is part of the IGEL UMS. It is designed to address the needs of large environments in which new settings need to be rolled out at once, or in which the fail-safe rollout of new settings is mission-critical for the organization concerned. The technical implementation is based on a network of several UMS Servers.
An upstream UMS Load Balancer takes over the load distribution and thus ensures that each device can receive new settings at any time – even at the start of a working day when a large number of devices log in to the UMS Server simultaneously and request new configuration profiles or firmware updates. To ensure maximum process reliability and high availability, IGEL also recommends that the UMS Load Balancer and the database have a redundant design.

Licensing with the IGEL OS 11 Licensing Model
The High Availability extension is included in the Workspace Edition, so that IGEL OS 11 devices can use a UMS High Availability network without an additional license.
