Cloud computing is the answer for “affordable” business technology platforms. It is a more affordable solution for media content than any other medium, and this is why Netflix, Amazon.com, and Apple are among the leaders in cloud usage and development. Ultimately cloud computing will be the primary way data services are accessed by businesses and consumers alike. Marston, Li, Bandyopadhyay, Zhang, and Ghalsasi 2009 conclude cloud computing offers companies the opportunity to deploy cutting edge IT services without the enormous upfront costs that deter so many organizations from making the investment in infrastructure. Now that affordable solutions are becoming more readily available it is likely that more small and

Cloud computing has been defined by NIST as 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 cloud provider interaction. Cloud computing can be considered a new computing paradigm insofar as it allows the utilization of a computing infrastructure at one or more levels of abstraction, as an on-demand service made available over the Internet or other computer network.

Cloud computing is revolutionizing the use software globally at a very rapid pace as it is completely redefining the economics of how software is purchased and used. Web 2.0 technologies and their underlying design precepts are responsible for the current and future generations of social networks (Bernoff, Li, 2008). Both have immediate and significant impacts on the operations of businesses and the major contributions each makes are explained in this analysis.

Infrastructure as a Service (IaaS) providers offer resources to their clients based on a pay-as-you-go manner. Amazon through its Elastic Cloud Computing (EC2) and Simple Storage Service (S3) are the key providers here. They are presented as a capability of using cloud infrastructure for the self-management of such resources as processing, storage, and other fundamental resources.

Lastly, the Infrastructure as a Service is a kind of cloud computing where the provider gives out basic storage and basic computing capabilities through a standardized form. It is meant to work on workloads by pooling together networking equipment, storage systems, servers, Centre space (Williams, 2012). GoGrid, Amazon and 3 Tera are some of the examples of this platform.

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Cloud computing is an internet based computing that depends on sharing computing with other resources rather than local servers or personal devices to handle applications. Cloud computing has fundamentally changed the way people view computing resources; rather than being an important capital consideration (Navavati, M., Colp, P., Aiello, B., & Warefield, A. (2014)). Cloud computing offers many potential benefits to organizations by making information technology (IT) services available as a commodity. IT services are services provided by IT service provider. Such services includes storing, retrieving, transmitting, and manipulating data for businesses or organizations.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

According to Prasad, Gyani and Murti (2012), “Cloud computing can be defined as a new style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet” (p.7). This statement is from five years ago, and although cloud computing is no longer considered new, this definition still describes what cloud computing means today. Cloud computing being private or public is becoming more primordial in the IT sector due to the numerous advantages it gives to its end users (Basmadjian et al. 2012). Since the interest in cloud computing keeps on increasing, efforts need to continue to evaluate current trends in security and privacy. Cloud computing

Cloud computing is be increasingly common in distributed computing medium. Data storage and processing utilizing cloud medium is be a way worldwide. Software as a Service (SaaS) , one of main models of cloud that might be presented in a public, private or hybrid network. whether we look at the effect SaaS has on many business applications in addition to in our day to day life, we could simply say that this deactivated technology is thither to stay. we could simply say that this deactivated technology is thither to stay. Cloud computing could be visible as Internet-based computing, in which software, the resources shared, and input are created obtainable to hardware 's on request . however utilizing a cloud computing model could

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

Trusted Computing: There have always been trust issues between users and cloud providers which is why most of the IT companies do not use cloud. However, this trust can be generated by including a third party known as remote server attestation [1] [4] and also by providing improved security policies. This states that secured data is the core operation rather than an add on operation and therefore the Trusted Computing system is essential because it encrypts the application and the data further giving the decryption key to the trusted program and information [13].

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)
