Basic definition of cloud computing is the use of the Internet for the tasks performed by the computers and communication gadgets such as desktop, lap tops, tablet pc and the smart phones. It is an Internet-based network model that enables on-demand access to a shared pool of computing resources such as networks, servers, storage, applications and services provided by a third party. Cloud Computing is a Service by using the network.The cloud computing service can be public, private or virtual private. The public service refers to service open to all users subscribing to the service provider, private refers to dedicated to one subscriber and virtual private means usage of public service but dedicated to one particular subscriber or certain groups of subscriber for their own organization purpose only.
The simplest thing that a computer does is allow the storage
and retrieval of information. Computer user may store photos, videos, spread
sheet and power point presentation materials. Software for spread sheet,
AutoCAD, business related software such as ERP, SAP and MIS is kept in the
computer or the server computer memory space. Maintenance and updating of the
software and hardware for the computer system usually demands skilled computer
personnel for computer maintenance and substantial amount of money to purchase the
hardware and software replacement or upgrading. There is company who kept a
huge amount of data and always need to expand their memory space as time pass
by. Huge size and high quality data storage is expensive. Software vendors
periodically upgrade their software and no more supporting the older version
after some period of time. Software user left with no choice, they have to
follow the software version up and pay the price. The above are some of the
issues faced by IT user and owner.
Looking into cloud computing which is offering computing needs
such as storing of information, photos, videos and software by using the
network or internet. Computer user can get at the same information and perform
the same tasks whether they are at workplace, at home or anywhere with internet
connection. This method of software and hardware systems operation provides
several advantages including potential cost savings for many businesses. This will
frees us up the storage size at the computer and no software upgrade need to be
purchased. This is due to accessing the cloud network is pay per use base and not need
to own the hardware and software.
There are a list of challenges faced using the cloud
computing such as data privacy security, reliability of the cloud system and
the software offered by the service provider. As example one provider such as
Google will provide software of their own interest and do not offer their
competitor’s software. Similarly cloud provider offering Adobe Acrobat will not
work with Microsoft Word causing interoperability of application issues. This
will limit the user flexibility to use whatever software at their own liberty
for achieving their best efficiency. The
incident faced by Amazon cloud outage causing the offline of website such as Qurora,
and Foursquare prove the reliability issue is a challenge and could stops a
business operation.
The decision to embrace cloud computing requires further analysis
to evaluate the risk base on the organization or the business needs. The
organization or business must have mitigation strategy to face the known or
potential problems due to the cloud computing to continue in business.
