In the
traditional model of implementation of Information Technology (IT),
organizations allocate material, human and technological, which are
grouped in an area responsible for solving the problems related to
infrastructure and application development for the organization.
Most
of these areas, are forced to spend much of their time on tasks to
deploy, configure, maintain and upgrade infrastructure-related
projects in your organization, which normally is not a value in the
balance final production thereof.
On
the other hand, it is observed that the distribution of services such
as Online data storage, large big data services, leave the full
responsibility provider to generate, organize and manage everything
for the end user receives the agreement, paying it solely for your
use thereof, while the supplier is responsible to clarify the
mechanisms by which determines consumption generated by the
collection.
Thus
emerges an interesting question: why not implement services or
resources under a scheme similar to that described, where the vendor
provides the user required and pay only for your use?
If
this happens, the user would not have to worry about acquiring
computer equipment and their respective maintenance, update
applications or operating system, it would be the responsibility of
the vendor.
It
is for this reason that organizations are directing their gaze to
this technology known as cloud Hosting (cloud computing), which is
able to minimize the time spent on lower-value activities and allow
the staff working in technology areas information, focus on strategic
activities that have a real impact on the business processes of the
organization.
Using
this concept is spreading with considerable speed, resulting in an
increase in the number of companies that provide services through
this technology, as well as organizations that are seriously
considering the adoption of cloud computing as a totally viable
alternative.
"The
cloud computing is a paradigm that can provide computing services via
the Internet, in this context, the cloud is a metaphor for the
Internet".
The
types of services that can be provided through the cloud are
extensive. According to this model, the client pays for a service
provider or by the use of a particular resource (memory, storage,
processing, software, databases, etc..) And this provides the service
via the Internet. The commercialization and standardization of
technologies, virtualization architectures and the growth of
service-oriented software and increasing the reliability of Internet
business solutions, are the foundations on which cloud computing has
managed to grow.
Advantages of Cloud Hosting Services :
1)
Costs : It could be the most attractive advantage presented by cloud
computing, and if not, at least it's the most obvious of all of this
technology. By leaving the responsibility of implementing the
infrastructure provider, the client does not have to worry about
buying computer equipment, train personnel for the setup and
maintenance of these, and in some cases, software development.
Furthermore, the user of these services you only pay for the
resources they use, letting you design a payment plan usually from
the time that it is used (memory, processing, storage).
2)
Competitiveness : By not having to buy expensive equipment, small
businesses can have access to the latest technology at prices within
reach paying only for consumption. Thus any organizations could
compete on equal terms in areas of IT companies of any size. The
competitive advantage is one that has the computing resources
employed but who the better.
3) Availability:
The supplier is obliged to ensure that the service is always
available for the customer. In this sense, virtualization plays a
key role as the provider can make use of this technology to design a
redundant infrastructure enabling it to offer consistent service
according to customer specifications.
4) Uptime:
The most required thing which allows number of clients to run
successful online without the downtime. The Connected server network
logic which works behind the cloud servers helps website to
distribute the generated load and helps to grow business.
5) Abstraction of the technique : As mentioned when talking about costs,
cloud computing allows the customer the ability to forget about the
deployment, configuration and maintenance; transferring this
responsibility to the service provider.
6)
Access from any location : Using applications designed on the
paradigm of cloud computing can be accessed from any computer
equipment in the world that is connected to the Internet. Access is
usually done from a web browser, which enables the application to be
used not only from a desktop computer or a laptop, but goes beyond,
allowing the user to use the application even from mobile devices
such as smart phones .
7)
Scalability : The client does not have to worry about upgrading the
computer equipment on which you are running the application using,
nor by the operating system upgrade or installation of security
patches, and it is the duty of the service provider this type of
updates. In addition, they are transparent to the client, so that the
application must still be available to the user at all times even
when you are performing the upgrade process at the supplier. Updates
and new features are installed almost immediately.
8)
Concentrated efforts in business processes : As a result of the
aforementioned advantages, the customer could focus more resources
and efforts towards a more strategic and transcendent, that has a
direct impact on the business processes of the organization,
transferring to the supplier the responsibility for implementation,
configuration and maintenance the infrastructure necessary to run the
application.
Disadvantages :
1)
Privacy :Understandably the perception of insecurity that generates a
technology that makes information (sensitive in many cases), on
servers outside the organization, leaving responsibility for the data
to the service provider. The subject here is the privacy, since for
many it is extremely difficult to trust your sensitive information to
third parties and consider the proposals of the cloud computing
threatens the vital information for business processes.
2)
Availability : While it is true that the availability previously
included as an advantage, it is a responsibility that falls solely to
the service provider, so if your redundancy system fails and can not
keep the service available to the user, this is not can take any
corrective action to restore service. In this case, the client should
wait for the problem to be solved at the supplier.
3)
Lack of control over resources : By having all the infrastructure and
even the application running on servers located in the cloud, ie at
the supplier, the customer completely lacks control over resources
and even on your information once it is uploaded to the cloud.
4)
Connectivity :In a solution based on cloud computing, the client
becomes dependent not only on the service provider, but also of your
Internet connection, because the user must be permanently connected
to the system to achieve that is in the cloud .
5) Integration
:Not at all easy or practical environments integrating available
resources infrastructure through cloud computing systems developed
in a traditional manner, so that this aspect should be taken into
account by the client to see how feasible it implement a cloud-based
solution within your organization.
