The Definition Of Cloud Computing

Cloud computing is a one of the most talked of topics in the field of Information Technology in recent times (Keyun, Joe, Taha, & Ibrahim, 2013). This subject area of cloud computing basically is a term used to describe computer resources available as a service accessible over a network (Darren & Kim-Kwang, 2013). The National Institute of Standards and Technology (NIST) define cloud computing as a model for enabling ubiquitous, convenient, on-demand network access on a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction (Peter & Timothy, 2011). Due to the attractive nature of the model there has been rise in the use of cloud computing. Gartner, an IT research and consulting firm, says that cloud computing is growing will become the bulk of IT spend by 2016 (Gartner, 2013).

There are different types of cloud computing services available on the market which falls into one of the following categories.

Cloud Computing is a process collecting the existing techniques and technologies , packaged within a new infrastructure that offers improved scalability , rapidly respond to change , faster start up time , reduced management costs and availability of resources for a short span of time .

There are a variety of definitions that are associated with cloud computing. However, the importance of how the technology is transforming business models greatly exceeds any specific definition. There are three components that are usually cited in any definition of cloud computing (Gabrielsson, Hubertsson, Mas, & Skog, 2010). The most commonly known component is the Software as a Service (SaaS). This allows organizations and consumers the ability to use software on demand and be billed for the usage on a per use basis.

As we all likely already know, there 's a lot of hype associated with cloud computing. Cloud computing encompasses diverse models and technologies. It is not just a paradigm or a concept that is forced into the enterprise by their thought leaders.

1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four

These private environments are made accessible via the Internet. Cloud computing provides services such as software (applications), platforms and infrastructures with a subscription-based in a pay-as-you-go model. These services are generally referred as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

But what is Cloud Computing, exactly? How does it work? How is it used? For what purpose? What can be improved in such technology? I will try to answer these questions during this report.

Anything that involves delivering hosted services over the Internet is Cloud computing. Cloud computing is a type of Internet-based computing where different services -- such as servers, storage and applications – are delivered to an organization's computers and devices through the Internet. cloud computing structure allows access to information as long as an electronic device has access to the web. Cloud computing system allows employees to work remotely. Examples of cloud computing include social networking websites and facebook.

The conceptualization of cloud computing can be explained from the below drawn figure. There are mainly two types of

Cloud computing has provide the software and services the demand of the client. It offer the client to connect to computer resources and access the resources with a previously unknown level of ease because of this new cloud become the new ground of development of a generation of delivering service and store the privacy and security may be include security concern among user of the cloud have become concern of cloud.

There are three service models for Cloud Computing, SaaS (Software as a Service), Paas (Platform as a Service), IaaS (Infrastructure as a Service). It is important for businesses to fully understand the knowledge about each models before investing on Cloud Computing.

Cloud computing is a novel tool that provides an opportunity for large or small business owners based on an entirely new business model. The term cloud computing itself is a familiar term, however, the specific meaning can be difficult to define. This paper discusses several facets of cloud computing topics to include cloud benefits, characteristics, as well as service models.

IAAS (Infrastructure as a service) - Allows the users to run any application of their choice on a cloud hardware.

“ Cloud computing does not yet have a standard definition, but a good working description of it is to say that clouds, or clusters of distributed computers, provide
