In the olden days of computers – and by that, we mean several years ago – it was likely that you stored most of your important data on your computer's local hard drive. That paradigm was fraught with danger and inconvenience. If your hard drive died (a depressingly common occurrence) or you wanted access to your data while you were out of town, well, good luck to you.
Widespread high-speed Internet access, better online storage services and cheap availability of both changed everything. Now you can store all of your documents, pictures and even videos in the cloud, a collection of computer servers that is always connected to the Internet. With your laptop, tablet, or smartphone and an Internet connection, you can view and manipulate your files in your office or 1,000 miles away from home. And more than 80 percent of businesses saw improvements thanks to the power of the cloud [source: Silicon Angle].
Cloud computing may seem magical, but it's not. It takes a lot of hard work and diligence to maintain a seamless end-user experience. For that, you can thank cloud computing specialists. Most commonly, the experts who run cloud services have extensive backgrounds as systems engineers, software engineers and network administrators.
The IoT requires these employees to design and build applications that work with a huge variety of connected devices. They need the know-how to roll out their products. And of course, someone has to play administrator for these systems, which can impact millions or even billions of devices. With nearly $200 billion going toward cloud services per year in the U.S. alone, companies of all sizes will roll out the cash for the best specialists [source: Silicon Angle].
