When to Use IGEL Cloud Gateway
The IGEL Cloud Gateway (ICG) is required if the UMS and the devices are not in the same network. The following scenarios are typical use cases for the ICG:
The endpoint devices (IGEL UD, UD Pocket or devices converted by UDC3/OSC) of all geographically dispersed branches of a company are to be managed by one central IGEL Universal Management Suite (UMS).
UD Pocket or devices converted by UDC3/OSC are to be managed by the UMS which is residing on premises.
For detailed information on UMS installation scenarios, see the Universal Management Suite > UMS Reference Manual > UMS Installation and Update > IGEL UMS Installation > Installation and Sizing Guidelines for IGEL UMS.
