Technically- What is cloud computing?
Cloud
computing is the provision that allows the user to log into a web based
service which hosts all the programs obligatory for completing the job.
The cloud computing service provider runs everything ranging from
emailing to word processing to different complex data analysis programs.
The term 'cloud' actually refers to the network of computers which
handle all the assigned respective tasks. Cloud computing service
providers charge for the Maintenance and management of data inputs by
clients. Cloud computing has emerged as the next big thing in the dome
of application software, storage, hardware and platform flexibility that
provides easy solutions to the most complex of things! The system
favors all sizes of business but proves really fruitful for middle and
small sized ones.
All one needs to avail the service is a basic
computer system, web browser and the internet. It has become the
lifeline of organizations who seek a simple solution to the compound
problem of choosing and organizing software as per each employee's area
of work. Have you ever noticed every internet user prominently benefits
from cloud computing? The finest examples of cloud computing are Gmail,
Amazon web services, Google applications where a browser helps the user
to access the application whenever she/he feels like.
How it works?
Knowing
how cloud computing works is interesting. The structural design can be
categorized into two main sections: Front end and back end. Front end is
controlled by the end user or client or say the web browser who uses
the cloud services. Back end is the network of servers with any computer
program and data storage system that runs, handles and maintains the
cloud (Succinctly- The service provider).
Cloud has a centralized
server administration system. The centralized server administers the
system, balances and adjusts client supply and demands, monitors traffic
and avoids congestion. This server follows a set of rules (protocol)
known as middleware. Middleware as the name suggests, is the
intermediary that allows networked computers to communicate with each
other. Observing the other side of the process one can rename cloud
computing as green computing because it helps in successful conservation of power energy.
Can Cloud computing be pocket friendly?
Cloud
computing is cost effective too. Unlike traditional computing, the
service condenses "Hard Costs" like cost of hardware, infrastructure,
software licenses, and "Soft costs" such as IT staffing,
troubleshooting, energy costs to run the servers, desktops and cooling
the entire server room. As far as data maintenance costs are involved
they too are quite reduced as they are maintained by the service
provider (They perform the complete set of tasks; from running the cloud
to storing data). The need to high storage hard drives can be snubbed
away as all the data is stored on a remote computer.
Breakdown of
the system can cause the owner a serious nervous breakdown because of
high data recovery and system repair costs, not to ignore the data loss.
In such situations, of course the show goes on because the data can be
operated from the remote computer from any place! if are you know about the

Market is in the
favor of buyer. Since past three years number of service providers has
swelled. In this computing arena we have crucial players like Microsoft,
Google, Amazon, Intel, and many others who are competing hard to build
effective and impressive clouds for their clients..
Brownie points for Cloud computing users!
Cloud
computing's pros do not end here. Databases in cloud computing are very
dynamic and scalable which means that local computers no longer have to
deal with hefty applications that almost kills the speed of the local
computer, and most importantly hardware and software demands on the
user's side decreases. But who plays the protagonist in the whole story
of cloud computing? Answer is Data. The cloud not only builds, runs and
maintains the data but it also secures it.
The data security is
the top most priority in all the data operations of the cloud.
Undoubtedly, the data is backed up at multiple locations. This is called
redundancy of data- the most important attribute of cloud
computing service. Another benefit of cloud computing is that the data
accessibility is not limited to any particular hardware or storage
device. The data can be accessed anytime and anywhere one needs to.
Is the right cloud chosen?
But
there are some important concerns that one should not avoid before
relying on the service. One of them is choosing the right form of cloud
computing from:
ï‚· SAAS (Software As A Service): Where users rent
application software and databases. It is commonly known as on demand
software. For example: ADP (long time provider of payroll services),
Google apps.
ï‚· IAAS (Infrastructure As A Service): Here the
cloud providers provide their client with servers (as many as client
needs) in exchange for the rent on each server. For example: "Amazon web
services" is one of the most successful IAAS provider till date.
ï‚·
PAAS (Platform As A Service): In this form of Cloud computing, users
rent the complete package of servers plus the required software to use
in them. For example: Salesforce.com is one of the much known PAAS
provider.
As per the business needs, the user should tactfully
choose the most appropriate form of cloud computing. Secondly, vital
decision in selecting the right service provider proves fruitful in long
run. One must make sure that the provider is reliable, is well-reputed
for their customer service and satisfaction, and should have a proven
track record in handling the respective business ventures. They should
be prudently equipped with proper techniques where data is segregated in
a clear and discrete manner. Data of different clients should be dealt
with utmost care and confidentiality. Most importantly, cloud computing
providers must be equipped with proper disaster recovery policies to
deal with any unfortunate event in future. Cloud computing can be the
apt choice which solves umpteen purposes in one go. It is the medium for
getting the best performing system with the best value for money. The
technology is worth embracing that tunes the business towards the set
objectives. After all, in the arena when life is pacing at the speed of
light, twenty four hours seem too precise to do the job. Business
actually needs the undivided attention of the owner, technology can be
taken care of by cloud computing service providers, then why risk
energy, time and mental peace? When one just needs to spend money.
