The biggest business use case for cloud computing is that you no longer need to buy expensive hardware or expensive per-user software licensing. Instead, those physical assets move off of your balance sheet and onto your profit-loss statement as tax-deductible, monthly utilities.
You’re getting all the benefits of that infrastructure, saving your cash flow, and not having to take on the risk that it might break and need costly repairs. Win, win, win.
You also don’t have to pay for expensive maintenance, configuration, or updates anymore. That’s all done by the cloud service provider and included in your subscription.
