					CLOUD COMPUTING




                  22-Oct-12
 DEFINITION:



“Cloud computing is an emerging computing
technology that uses the internet
and central remote servers to maintain data and
applications”.
       INTRODUCTION
   The underlying concept of cloud computing dates back to 1960, when
    John McCarthy opined that "computation may someday be organized
    as a public utility"; indeed it shares characteristics with service bureaus
    that date back to the 1960s.
    The actual term "cloud" borrows from telephony in that
    telecommunications companies, who until the 1990s primarily offered
    dedicated point-to-point data circuits, began offering “VIRTUAL
    PRIVATE NETWORK (VPN)” services with comparable quality of
    service but at a much lower cost.
   The cloud symbol was used to denote the demarcation point between
    that which was the responsibility of the provider from that of the user.
    Cloud computing extends this boundary to cover servers as well as the
    network infrastructure.
   Cost is claimed to be greatly reduced and capital expenditure is
    converted to operational expenditure. Device and location
    independence enable users to access systems using a web browser
    regardless of their location or what device they are using.



                                                                                  3
     USES


   Helps to use applications without installations.
   Access the personal files at any computer with
    internet access.
   This technology allows much more efficient
    computation by centralizing storage, memory,
    processing and band width.

      SURVEY

   Based on a study conducted in June 2009 by version one,
    41% of IT senior professionals doesn’t have sound
    knowledge on cloud computing.



   In September 2009, Aberdeen Group found that 18%
    reduction in there IT budget and a 16% reduction in data
    center power costs.





             A cloud client consists of
             computer hardware and/or
             computer software that relies on
             cloud computing for application
             delivery.




                                                  6
       APPLICATIONS

   Cloud application services or "Software as a Service
    (SaaS)" deliver ‘software’ as a service over the Internet,
    eliminating the need to install and run the application on
    the customer's own computers and simplifying
    maintenance and support.
    PLATFORM



   Cloud platform services or "Platform as a Service
    (PaaS)" deliver a computing platform and/or
    solution stack as a service, often consuming cloud
    infrastructure and sustaining cloud applications. It
    facilitates deployment of applications without the
    cost and complexity of buying and managing the
    underlying hardware and software layers.


                                                           8
 INFRASTRUCTURE

Cloud infrastructure services or "Infrastructure as a
Service (IaaS)" delivers computer infrastructure,
typically a platform virtualization environment, as a
service. Rather than purchasing servers, software,
data center space or network equipment, clients
instead buy those resources as a fully outsourced
service. The service is typically billed on a utility
computing basis and amount of resources
consumed (and therefore the cost) will typically
reflect the level of activity. It is an evolution of
virtual private server offerings.


                                                        9
    SERVER

   The servers layer consists of computer hardware
    and/or computer software products that are
    specifically designed for the delivery of cloud
    services, including multi-core processors, cloud-
    specific operating systems and combined offerings

    DEPLOYMENT MODELS


COMMUNITY CLOUD:

               A community cloud may be established where
several organizations have similar requirements and seek
to share infrastructure so as to realize some of the benefits
of cloud computing. With the costs spread over fewer users
than a public cloud, this option is more expensive but may
offer a higher level of privacy, security and/or policy
compliance.
Examples of community cloud include Google's "Gov
Cloud".

                                                                11
        HYBRID CLOUD & PRIVATE CLOUD
HYBRID CLOUD:
                 A hybrid cloud environment consists of multiple internal
and/or external providers "will be typical for most enterprises". By
integrating multiple cloud services, users may be able to ease the
transition to public cloud services.


PRIVATE CLOUD:
                  Private cloud and Internal cloud are expressions that
some vendors have recently used to describe offerings that emulate cloud
computing on private networks. These products claim to "deliver some
benefits of cloud computing without the pitfalls", capitalizing on data
security, corporate governance, and reliability concerns. They have been
criticized on the basis that users "still have to buy, build, and manage
them" and as such do not benefit from lower up-front capital costs and
less hands-on management

                                                                            12
       CRITICISM
   Richard Stallman, founder of the Free Software Foundation and
    creator of the computer operating system GNU, said that cloud
    computing was simply a trap aimed at forcing more people to buy
    into locked, proprietary systems that would cost them more and
    more over time. "It's stupidity. It's worse than stupidity: it's a
    marketing hype campaign," he told The Guardian.
    "Somebody is saying this is inevitable – and whenever you
    hear somebody saying that, it's very likely to be a set of
    businesses campaigning to make it true." "The interesting
    thing about cloud computing is that we've redefined cloud
    computing to include everything that we already do," he
    said.
   The main drawback behind the concept of Cloud Computing is
    we can’t completely rely on third party when we are transmitting
    sensitive data.
                                                                         13
    ISSUES
PRIVACY:

The Cloud model has been criticized by privacy advocates for the
greater ease in which the companies hosting the Cloud services
control, and thus, can monitor at will, lawfully or unlawfully, the
communication and data stored between the user and the host
company.
Instances such as the secret NSA program, working with AT&T, and
Verizon, which recorded over 10 million phone calls between
American citizens, causes uncertainty among privacy advocates,
and the greater powers it gives to telecommunication companies to
monitor user activity.

     LEGAL

   In March 2007, Dell applied to trademark the term "cloud computing"
    (U.S. Trademark 77,139,082) in the United States. The "Notice of
    Allowance" the company received in July 2008 was cancelled in
    August, resulting in a formal rejection of the trademark application less
    than a week later.

   Since 2007, the number of trademark filings covering cloud computing
    brands, goods and services has increased at an almost exponential rate.
    As companies sought to better position themselves for cloud computing
    branding and marketing efforts, “cloud computing trademark
    filings increased by 483% between 2008 and 2009.” In
    2009, 116 cloud computing trademarks were filed, and trademark
    analysts predict that over “500 such marks could be filed during
    2010.”
                                                                                15
                          SECURITY


   The relative security of cloud computing services is a
    contentious issue which may be delaying its adoption. Some
    argue that customer data is more secure when managed
    internally, while others argue that cloud providers have a
    strong incentive to maintain trust and as such employ a
    higher level of security.




                                                                 16
     CONCLUSION

   Cloud computing is a better way to run your
    business. Instead of running your apps yourself,
    they run on a shared data center. When you use any
    app that runs in the cloud, you just log in, customize
    it, and start using it. That’s the power of cloud
    computing.
   Finally, cloud apps don’t eat up your valuable IT
    resources, so your CFO will love it. This lets you
    focus on deploying more apps, new projects, and
    innovation

        THE BOTTOM LINE

Cloud computing is a simple idea, but it can have a
         huge impact on your business.
