It is very complex.<p>That&#x27;s exactly why SaaS disrupt traditional enterprise on-premises software - too complex (installation, user interface), too expensive upfront.<p>If the software requires no 3 weeks installation phase, no handbook nor training and costs a fraction of the usual 100k to 1m, like $200&#x2F;host&#x2F;month, then there is often a clear winner.
