The cloud revolution has made an enormous contribution to the evolution of sales and marketing software, as well as to business software of all types. There’s a long list of benefits it’s conferred on its users — from the ability to outsource security and maintenance tasks to the avoidance of manual upgrade processes, to — most significantly — the switch in payment modes, to a model more affordable for more businesses. It’s also made deployment much, much easier: Sign the contract, log in and go. That’s great.
