How does Cloud Storage work ?

 Data of the user is stored in servers that are in remote locations. The
user is connected to the server where his/her data is stored via the
internet. Now the user uploads data into the internet and sends it to the
data server connected. This data server sends the same data to different

servers stored remotely. This data when needed, users can access
through the internet.
 The data is stored in different servers because the server through which
the user is connected may not be available at the time of his need. If the
server faces a problem due to maintenance, less worried is the user

because the data is stored in other servers as well. This storage if in the
public cloud, the primary storage will be near the physical location of
the user due to its faster availability and lower cost. Public clouds have
servers, storage, networking, and data centre operations as their
services.
 Cloud services are used by paying a certain amount fixed by the service
provider based on the storage and usage of the end-user. Users who

know their usage can pay the amount prior to the usage and then a
monthly rental will be almost free. A service provider can also add the
servers on a dynamic basis and here the payment is based on a pay per
use basis. Cloud storage can be personal, private, public and hybrid
cloud storage.

 The difference between personal and private being personal storage will
be mostly owned by a person to store graphics and texts while private
will be owned by a company for its data storage. Most of the cloud
storage is virtual machines that have servers located elsewhere around
the globe. We can upgrade the cloud storage once the storage option
changes according to the data to be stored.

Advantages

Below are the advantages mentioned:

o Data is accessible from any parts of the world with the help of the internet
as it is stored online in servers.

o Data can be shared easily between persons or devices with cloud storage.

o Communication with the data can be done easily as the sharing is done
automatically by providing a link like Google Drive.

o Companies need not worry about the maintenance of the storage devices
as it is managed by a service provider.
