What is cloud storage?

Cloud storage is a recent technology that allows internet users to store all their data on an online server.

You can store, edit, share and delete files, documents, photos, videos, contacts and apps freely.

Cloud storage eliminates the need for local storage. Whether on a desktop computer, a notebook, a smartphone or a tablet, it is not necessary to have a physical HD (hard disk) to store information.

Everything is stored and available in a digital environment.

To access these files stored in the cloud, the user just needs a stable internet connection. It is used to manage and edit files and folders stored on the online server.

This can be done from anywhere away and at any time of the day as long as there is internet to use.

How does cloud storage work?

You already know what cloud storage is. It’s time to learn how the technology works, which has conquered more and more users.

Big technology companies like Microsoft, Google and Apple maintain data centers with thousands of servers running 24 hours a year all year round.

These servers, which have very high storage capacity and are located miles away from the user, are connected to the internet.

When the user accesses a cloud storage service, he enters at least one of these servers. In it, you can send your files over the internet and have them safely stored in a matter of seconds.  

Uploaded files are automatically saved and distributed on several different servers. So, if one of the servers fails, the user is never without access to his files available on the other servers. And you never lose what you keep there.  

Benefits of using cloud storage

  6. Feature Customization . While many of the cloud storage services are free, there are customized plans for single users and companies. If you need more space and more functionality to manage a project, you can always subscribe to a more robust package. Of course, in this case, there will be more costs as well.
