You work in an environment in which new settings need to be rolled out to a great number of endpoint devices at once or in which the fail-safe rollout of new settings is mission-critical for the organization concerned. Too many simultaneous requests from the devices for one UMS Server may lead, however, to intermittent failures. As a result, the devices will not get new settings during the boot process.
You need a method that ensures that every device can get new settings at any time, even at the start of a workday shift when a large number of devices may simultaneously contact the UMS Server via LANs, WLANs, and WANs, searching for new configuration profiles or firmware updates.
An upstream UMS Load Balancer handles load distribution. To ensure maximum process reliability and high availability, IGEL recommends that you use the UMS Load Balancer, the UMS Server, and the database in a redundant setup.
