Friends
First we shall see why the name “cloud computing” comes into
existence for this technology. There is nothing in sky, it is all clear. We
named this technology as cloud computing because it resembles in structure like
cloud. We know that cloud is made up of water vapor whose structure is not well
defined. It can move here and there, may be present for some time or not at
all. Similarly the cloud computing technology is made from different networks
and users. Users may be fixed or not but the technology will always be present
for its services as cloud rains anytime.
Cloud computing in real life
Suppose you have a computer system in your home and you do
normal work with this computer like your assignments, games, movies, stores data
etc. you can do these tasks easily with your current computer system. Now
suppose you have to play a high-end game or you have store a huge amount of
data or you want to use some software which are not installed on your computer
and you have to pay premium for usage. In this case one possibility is that you
will buy an advance computer with the software that needs license for its use.
Overall you will make a new set-up for your personal use. Second possible
solution is that with the help of high speed internet. If you have speed
internet then it will be beneficial to use advance system of service provider
on rent. In this deal you can access the advance system and with help of
internet you can do your work on your system. Same concept is used in cloud computing.
Cloud computing is not only for storage, people thinks that cloud computing is
used to data in clouds as we see names like Google drive, drop box, one drive
etc. but is more than storage here services are provided to you. Many companies
are dependent on cloud computing. Let there is a company in which thousands of employees are working, then there will be data
of the employees plus data of company or the software that they use of service
that they provide. In this case, to maintain all these data, company has to
establish a dedicated unit for this purpose. But if company deals with cloud
computing service provider, there are many companies which provides this
services, to provide this facility. It will cost negotiable to the firms and it
will also be helpful in case number of employees’ increases in that company or
some other data. Simply you can scale up storage size as per your need sometime
it will be 100 GB or sometime 10 GB, depends on your job. But if want to do
physically in your business, school or firm it will cost more to you.
Cloud computing is win-win situation for the user as well as
for service provider. Suppose I maintained a facility of 10000 GB in my house
and I made a announcement in my locality that register 500 GB storage with nominal
charges and I will made a arrangement through internet that you can easily
access this storage and I will make it secure with encryptions and advance
security systems. At any time with help of internet you can access data through
your mobile for laptop anytime anywhere.

What I discuss above is basically idea of cloud computing.
Online gaming are more popular through cloud computing, you can play high end
game with this technology. In this case you don’t need an advance computer you
need only high speed internet. If you have high speed internet then you play
online game or use Photoshop it doesn’t matter. All the services like MS word,
Excel, storage which is easily available at a platform and you need not to stay
at place physically i.e. use laptop or tablet or mobile anywhere anytime. You can access your data with password and
user id.
Now I think you get the idea that what is cloud computing.
Lot of companies and providers provide this service. It may vary in fields and
plans. With some premium you can take this service according to your need. If I
choose Google drive and I store a data of 100 GB then it will be responsibility
of Google to secure my data.
Google photos are a cloud based services by Google, one
drive by Microsoft etc. In future the
demand for cloud computing will be more.
