Cloud Storage: What It Is, Why it Helps and How It's?Secured
Whether we realize it or not, we are constantly impacted by cloud storage. Perhaps you begin your work day by opening a Google Doc or an email sent to you via Gmail. Both of those platforms are dependent upon cloud storage. Or perhaps you spend your lunch hour checking Facebook, Instagram or YouTube. All those platforms make use of it as well.
It’s all around us, whether we’re downloading cat videos or toiling away on a big project, and impacts us most directly when we want to back up or store our own personal data — as will increasingly be the case. Spurred by the advent of such cloud-storage systems as Google One, Amazon Cloud and OneDrive, the cloud storage market size is expected to be $49.13 billion in 2021, then jump to $297.54 billion by 2028, a CAGR of 25.3 percent.
Cloud storage is particularly popular in the business world, as some 85 percent of enterprises around the world use it.
But what is it, really?
It consists not of storage in some mystical place free of Earth’s bounds (as its name might suggest), but in far-off data centers, where files of all sizes are secured and backed up but also constantly accessible to owners via the Internet. In fact, users — who pay for the service either via subscription or on a per-consumption basis — can access their information courtesy of any device.
It is, in other words, a sizable step beyond storing information on thumb drives or external hard drives. It has also been particularly useful during the coronavirus pandemic, given many companies’ pivot to remote work. Files can be shared, and it is possible for multiple users to access a file at the same time. In other words, collaborative projects are a breeze when cloud storage is involved.
Security is, of course, a constant concern, especially given how much data is going to be out there in the years to come. While there were some 33 zettabytes of data (the equivalent of 33 trillion gigabytes) throughout the world in 2017, that total is expected to mushroom to 175 zettabytes in 2025. And rest assured that cybercriminals are always lurking.
The countermeasures adopted by cloud servers are considerable. Most take steps such as encrypting files, storing them behind firewalls, and availing users of two-factor authentication. Some even resort to artificial intelligence to scan their system for weak spots.
In addition, most services make multiple copies of files and store them at various data centers — a practice known as redundancy — to preclude their loss in a natural disaster. A 2019 report even noted that there are occasions where these services back up data on magnetic tape, often considered a relic of a bygone era but actually a reliable, secure means of storage.
The long and short of it is that we continue to be enveloped by the cloud. It is all around us, at all times, and enables us not only to store an ever-increasing amount of data, but also to access and share it. All of that is valuable — particularly the latter, and particularly now.
