WHAT IS CLOUD COMPUTING?
Cloud computing is a model for enabling 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.
Cloud computing incorporates virtualization, on-demand deployment, Internet delivery of services, and open source software. From one perspective, cloud computing is nothing new because it uses approaches, concepts, and best practices that have already been established. From another perspective, everything is new because cloud computing changes how we invent, develop, deploy, scale, update, maintain, and pay for applications and the infrastructure on which they run.
ARCHITECTURE OF CLOUD COMPUTING
From a general perspective, when the architecture of the cloud is considered, it can be divided into front end and back end. They are connected with each other via a network and mostly internet is used for fulfilling the requirement. The front side is the interface for the user i.e. the client and the back end is the cloud section for the whole system which acts as the server.
Front End
The front end of the cloud computing system comprises the client’s device (or it may be computer network) and some applications are needed for accessing the cloud computing system. Different cloud computing systems have different interfaces for the users. Front end is basically a technical term which refers to the interface though which a user can use some kind of services.
Back End
Back end refers to the some physical peripherals. In cloud computing back end is cloud itself which may encompasses of various computer machines, data storage systems, servers. Group of these clouds make a whole cloud computing system.

    Term Paper Intro to I.T.

    Cloud computing is one of the leading buzz terms in the world of IT today. Seemingly every possible solution has been enhanced with the mere addition of the word “cloud”. Cloud computing refers to applications and services offered over the Internet. These services are offered from data centers all over the world, which collectively are referred to as the "cloud." This metaphor represents the intangible, yet universal nature of the Internet. The idea of the "cloud" simplifies the many network connections and computer systems involved in online services. In fact, many network diagrams use the image of a cloud to represent the Internet. This symbolizes the Internet 's broad reach, while simplifying its complexity. Any user with an Internet connection can access the cloud and the services it provides. Since these services are often connected, users can share information between multiple systems and with other users. Examples of this technology include online backup services, social networking services, and personal data services such as Apple 's MobileMe. Cloud computing also includes online applications, such as those offered through Microsoft Online Services. Hardware services, such as redundant servers, mirrored websites, and Internet-based clusters are also examples of cloud computing. ("Technology terms," 2009)…

    In other words, cloud computing allows to store all personal and business applications without the data centre. This means that with cloud computing no sophisticated hardware is needed, which leads to great benefits for businesses. Cloud computing provides several hosted services on the Internet. These provided services are divided into three major categories: Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) (Barnatt, 2013). According to Bizarro & Garcia…

    Business Value of Cloud Computing

    Cloud computing offers software and hardware resources and in some cases human services over a distributed environment that can be shared and utilized on demand through internet. Business owners can use these resources as per their requirement even if that is for few hours a day or few days a month and have to pay only for that actual use. Thus this relatively new concept is becoming highly popular among IT organizations because of its flexibility and cost effectiveness. It is highly scalable and also can span quickly according to the requirements of individual organization yet still sharing the same resources.…

    Unit VI Research Paper The cloud and We

    Cloud computing is when an individual or company no longer uses their hardware or software on their computers or through their company network to store and access computerized information but, instead they use a service from another company through the internet in different locations worldwide. “ We define the cloud as the elastic leasing of pooled computer resources over the internet” ( Kroneke, 2013). Use of browser queries, web-mail, and document storage are a few examples of using the cloud, when we use these applications we outsource to servers located throughout the world, or use the cloud, the information is transmitted to the cloud and can be accessible anytime an individual or organization needs that information to be returned to the computerized device they are accessing. Cloud computing would make programs that you have to upload and use on your computerized device somewhat obsolete because of the same programs and software being easily accessed as a web-based entity, which makes life easier for busy individuals and organizations. Another wonderful concept of using the cloud would be that these server companies pay for these services by advertising and through other services that are paid for in advance, so we can access without cost.…

    Cloud Computing

    And like many, they found it a challenge to provide an encompassing definition for cloud computing. Foster et al. defined cloud computing as, “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet”; while SYS-CON Media Inc., 2008 [2] provided a list of definition from twenty one subject matter experts. Nevertheless, there was a general consensus [1][2][3] that cloud computing could be characterized by its very large scale, virtualization, versatility, scalability, on-demand, high performance, and low storage and usage costs.…

    Inf 103: Computer Literacy

    The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology services over the internet to many users in an on-demand environment (P.Y. Thomas 2011). As you can see by the definitions above the term Cloud Computing has been defined, yet many of us are barely getting to understand how this type of computing affects the work we do both in our personal life and in the workplace. In the following pages you will see how cloud computing is the way of the future without it being limited to business applications; furthermore creating a niche in the social media/personal computing we do on a daily basis.…
