More and more "stuff" is moving to the cloud. Microsoft, Apple, Adobe, and Amazon are just four of the biggest companies that are trying to get us to put everything in the cloud so we can pay a monthly fee to get to our "stuff." The problem with this is that from a customer perspective, the "cloud" does not scale up well from a pricing perspective.
In the "old days," by which I mean about three years ago, you made a one time purchase of a desktop or laptop computer, cobbled together some kind of local network for your business or home, and if you were really smart, bought one or two extra hard drives for backups and file sharing. A relatively substantial capital expenditure, but you had no recurring costs to use and to store you data and files.
Enter the cloud: You still get to buy a bunch of computers, laptops, and smartphones, but now you pay every month to use your own data. The revenue already being generated by cloud services is staggering, and will continue to grow for a while. But uncontrolled growth is, in the biological world, cancer. It eventually kills you...or in this case, wrecks your budget. All these $5, $10, and $20 per month cloud services add up. Small businesses that have to pay for cloud services on a per seat basis (or some other incremental use charges) can quickly max out their limited IT budgets.
The cloud is immensely useful, and like anyone else, I like being able to access my "stuff" wherever I am in the world. But it comes with a price, and one day the market growth is going to fall of a cliff. When that happens, expect many cloud services to go belly up--for anything in the cloud, you should be able to answer this question: "What happens if your cloud provider disappears?"
