The cloud explained

By Kaye Foley

We’ve all heard of it. And chances are good you’ve come across it in some way or another if you use the Internet. (And I’m assuming you do, since you’re reading this right now.) I’m talking about “the cloud,” and so far, forecasts have called for recognition but little understanding.

So let’s clear it up.

The cloud is actually a network of computers that work together, performing different functions, to help store and process enormous amounts of data. This is called “cloud computing,” and these computer networks are housed inside warehouses across the globe known as “data centers.”

Rather than saving your files locally on your computer’s hard drive, you can go online and send your digital belongings to these data centers, where there’s practically unlimited storage space. This means as long as you have an Internet connection, you can access your files anytime, on any device.  

But the cloud isn’t useful only as personal storage space. Businesses are getting into cloud computing as well. Big tech companies, like Amazon and Google, own and operate cloud computing platforms and offer space on the cloud to other businesses. For example, Netflix’s operation is powered through Amazon Web Services. Businesses save on costs and increase efficiency when they don’t need to maintain their own software, hard drives or computer networks.

It’s not all sunshine and rainbows, though. Some experts and users worry about the security of the cloud. Just take a look back at the iCloud software glitch in 2014 that allowed hackers to release private photos from the personal accounts of celebrities. Options for safeguarding against these attacks include using strong passwords and two-step verification as well as encrypting material before sending it to the cloud.

There’s also concern over cloud control. When an item is deleted, how can you be sure it’s completely gone? And who owns the files uploaded to the cloud--you or the company? Well, that comes down to reading the fine print and ultimately trusting the company. 

Still, this cloud cover isn’t rolling away anytime soon. Ninety percent of global Internet users are on it, and 80 percent of small businesses in the U.S. are expected to use cloud computing by 2020. So at least after watching this video you can say, “Now I get it.”
