The use of cloud computing creates a growing interdependence among both public and private sector entities and the individuals served by these entities. This paper provides a snapshot of the advantages of cloud computing and the risk areas specific to cloud services which clients of cloud services should be aware of. The future of cloud computing is certainly exciting, but moving more of our lives online means we will inevitably have to consider the consequences. Cloud computing means dependence on others and that could limit our privacy because

Cloud computing has evolved with the passage of time and has revolutionized the entire ICT industry. Cloud computing is categorized into two forms Service oriented computing and Grid Computing. Service oriented Computing is an transpiring paradigm that has revamped the consumption of software and related product all around the globe. The core functionalities that service oriented computing provide is elements and that are independent of platforms and are programmed using standard protocols to support distributed computing across various organizations.

of organization, are discussed. Characteristics of cloud computing discussed to get idea what the cloud computing is all about using. In addition to that, deployment model of cloud computing is discussed in greater detail to explain cloud computing can be used as public, private or hybrid type. Based on service delivery cloud computing divided into three types Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are explained further in this section.

The cloud computing, in comparison with personal computing, offers an extensive range of competencies. Cloud computing is defined in broader terms 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.”12

Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.

When using ordinary computing, we install software programs on computer and update the hardware as per our requirements. Documents we create or save are stored in our computer. Documents are accessible on our own network, but they can’t be accessed by computers outside the network. Cloud computing, the software programs aren’t run from one’s personal computer, but are rather stored on servers accessed via the Internet. Cloud Computing provides resources and capabilities of Information Technology such as SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service),HaaS (Hardware as a Service) to distribute the powerful computing capacity to end-users. However, still there exist many problems in cloud computing today, the current researchers or practitioners pointing that data security and privacy risks have become the

Cloud computing is the new buzz in the recent days and cloud computing allows users to share files and applications over the internet. In the following pages we will discuss about the cloud computing its pros and cons, the security risk and how to overcome and use its resources for the best advantage of organizations. It is attracting much of the attention now-a-days which can be seen by observing the big names of the IT industry like IBM, Microsoft and Google investing millions of dollars into research on cloud computing.

“Cloud Computing‟ is the next natural step in the evolution of on-demand information technology services and products. To a large extent Cloud Computing will be based on virtualized resources” [2].

Cloud computing provides three important types of services in the cloud environment: Software as a service (SaaS), Platform as a

The boom in the cloud computing world has led to a new era of on demand delivery of hosted service over a shared network. Cloud computing is a complex infrastructure of software, hardware and storage that is available as a service. It has flexibility rendering user to customize the service suited to his needs. Innovations in virtualization and distributed systems have paved the path for interest in cloud computing.

The Cloud Computing refers to “Computing over the Internet”.It came from Grid,utility and web services.It is a combination of network,servers,storage ,operating system and virtualization technologies to form a shared infrastructure that enables web-based value added services.End users access cloud-based applications through a web browser or a light-weight desktop or mobile application.The business software and user 's data are stored on servers at a remote location. The cloud model comprises five

The previous chapter demonstrated the key fundamentals of the research and an introduction to the concept of Cloud Computing. Even though a lot of research work has been done on the subject of cloud computing, the field is still a relatively new academic field. The National Institute of standards has established the standards related to Cloud computing and the research into the subject continues, especially with new tools and technology infrastructure that continues to evolve at a very fast pace.

Cloud computing is currently being used by a large number of organizations. Many consider it a major development of the decade in computing. In this article I define cloud computing, various services available on the cloud infrastructure, then discuss the technological trends which have led to its emergence, its advantages and disadvantages, and the applications which are appropriate to outsource to a cloud computing service.
