Explain in your own words the concept of cloud computing Do

Explain, in your own words, the concept of cloud computing. Do you believe that cloud computing will have a major impact on the IT function in organizations? Why or why not? In your opinion, what are some factors that will hold back the growth of cloud computing?

Solution

Main concept of Cloud computing:
-->It is a distinct IT environment designed for the purpose of remotely provisioning scalable and measured IT
resources.It is a distributed data processing in which some scalable information resources and capacities are
provided as a service to multiple external customers throught internet technology.

   The basic conectpts includes:
   1.SaaS(Software as a service):
       It is a business model of software license,which involves the development and support of the
software vendor.Customers also have the opportunity of paid use of it,usually through the internet.
  
   2.Paas(Platform as a service):
       It is an integrated platform for the development,deployment,testing and support of web-applications.
   presented as a service on the basis of the concept of cloud hosting service.

   3.Iaas(Infrastructure as a service):
       A computer infrastructure,typically presented in the form of virtualization.Is a service within
   the concept of cloud hosting.

Impact of cloud computing on IT functions:

1)The creation of a new generation of products and services. The economics of cloud computing lets innovative companies
create products that either weren\'t possible before or are significantly less expensive than the competition.Every improvement
in storage, processing power, or technology enables innovations that weren\'t possible before and cloud computing makes these
opportunities unusually accessible. Smart companies will take notice.

2)A new lightweight form of real-time partnerships and outsourcing with IT suppliers.a large part of what used to be in-house
is now being done somewhere else and changing anything is hard. But unlike traditional outsourcing of IT, cloud computing
will provide agility and control that traditional outsource cannot match for the most part.

3)A new awareness and leverage of the greater Internet and Web 2.0 in particular.When cloud computing is adopted by an organization,
they will find themselves thrown into the pool with the rest of the online world in many ways, whether this is the employment of
social tools, SaaS, non-relational databases or a host of other technologies in their new cloud. And in the end, this will
them very well and allow many companies to acquire the skills and perspectives required to compete effectively in the 21st century.

4)A reconciliation of traditional SOA with the cloud and other emerging IT models. A great post this week from our very own
Joe McKendrick illustrates how SOA is evolving because of the cloud. The advent of cloud technologies will have to be dealt
with and somehow encompassed by SOA initiatives that are already looking at their current toolset of heavyweight approaches
and technologies with an eye towards seeking an onramp to change and improvement. Web-Oriented Architecture fits very well
with cloud technologies which are heavily Web-based and it\'s a natural, lightweight way of building SOA at virtually every
level of the organization.
