The following installation and sizing guidelines are intended to support you with setting up the IGEL Universal Management Suite environment – UMS Server, UMS Console & UMS Web App, database, and, if required, load balancer and ICG instances.

General Installation Recommendations

For small installations, a single UMS Server instance (standard UMS) with an embedded database is usually sufficient. If required, a single-instance installation can be easily extended anytime to a Distributed UMS installation by installing additional servers (and in the case of an embedded database, by switching preliminarily to an external data source).

Large installations should use either the UMS High Availability or the Distributed UMS (preferable for new installations, e.g. because you do not have to configure additional firewall exclusions). For large installations, it is also recommended to use DNS-Round-Robin load balancing or IGEL Cloud Gateway.

* UMS Console can be installed on UMS Server host. 

** Follow the recommendation of the external database system on RAM and CPU. 

*** RAM and CPU requirements are less than in the case of M / S (HA) installation since the UMS Console is installed on a separate host machine (UMS Console Standalone = Mandatory).

**** General recommendation: 1 UMS Server per 50,000 devices, 1 load balancer for 3 UMS Servers.
