People all over the world are using cloud computing systems nowadays
without even realizing it like in our studies and work through Gmail, Facebook,
Google documents, etc.. In this report I’ll explain what cloud computing is, Where the term “cloud
computing” comes from, reasons and benefits, advantages
and disadvantages of cloud computing along with examples.
“Anthony T.Velte, Toby J.Velte &Robert
elsenpeter, 2010”Cloud computing is a term that
applies to applications and data storage that are delivered over the Internet.
The individual user's device like computer provides an interface to interact
with the computer programs and data. The programs are run on the service
provider's computers and the data is stored where ever the provider deems
necessary. This way the applications are available where ever you have a
connection to the Internet or wireless network.
The term
cloud computing originally comes from the visual image of cloud in the sky but
this cloud is a cloud full data that floats out on the internet and that can be
accessed from anywhere with an internet connection on any computing device which
developed from web _hosted applications.
Fortunately, through cloud computing
they can share software, servers and data and other devices instead of developing
their own networks and servers. In short, cloud computing is the things we do
with our computers like office tasks and files storing, except that it’s done
online.
“What is Cloud Computing, video recording”
Cloud offers several advantages to small and medium size business in
terms of reduced costs. You pay for what you use, in other words that
individuals who have good business ideas but don’t have enough money and have limited
funding and budgets for office space and private servers, networks, storage
space and teams of experts so don’t have a chance to even start working as its
expensive to finance these ideas.
“Advantages and Disadvantages of Cloud Computing” Cloud computing like anything else has its advantages and
disadvantages. Its advantages can be summarized with several points. First,
reducing Costs; it helps to reduce both capital and operating costs, through
economies of scale. To use an analogy, it is like replacing the electricity
generator in your home by plugging into an electricity supply. Because you need
only a computer and to be connected to the Internet costs are significantly
reduced. Another example is like when a vendor supports a hundred customers
with his bank of servers and support staff, the cost for each individual customer
goes down. Second, increased Storage; organizations can store more data than on
private computer systems, as their data and information is stored online.
Third, highly Automated; no longer the It personnel need do to worry about
constant server updates and other computing issues, as software and other
applications are automatically updated , this allows the IT staff to concentrate on
innovation and creativity to improve services and outputs. Finally, flexibility
and mobility; cloud computing offers much more flexibility than past computing
methods. Because this information can be accessed wherever they are, rather
than having to remain at their desks in the office.
As for disadvantages. First, additional
cost of data transfer fees. Second, one does not have control over the remote
servers, the software, or security. Finally, one’s data is at the mercy of a
third-party company so better make sure they earn your trust.
With the growing demand for IT cloud computing presents itself as an
all-in-one solution, being able to satisfy the growing IT needs while, at the
same time, reducing energy usage at an affordable price.
