a number of Ivanti Connect Secure (ICS) appliances,
but this can introduce other challenges, suchas inconsistent user experience, and uneven useof resources:■ Poor performance: Uneven distribution of user

ICS

sessions across ICS clusters can result in some
appliances becoming congested, impacting
performance and productivity■ Rejected sessions: If sessions are not evenly

distributed, and a ICS appliance uses all available
licenses, then new sessions will not be accepted,
and other users may be disconnected■ Slow connection for mobile users: Mobile users

need to be connected to the nearest available
location for a truly global service, to avoid
slow connections or route around regional
network outages■ Maintenance downtime: Ivanti Connect Secure(ICS) appliances can be clustered together using
a network load balancer, but adding more ICS
appliances may require downtime or outage toimplement configuration changes
