The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of
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 :
The top Cloud Service Providers (CSPs) in our market are various. Most of them have their special advantages for surviving in fierce business competitions. Some may have advantages on mobile app, some may have advantages on languages, customer help and support services or prices, or others may pay more attention on security protection and their reputation improvements. In this assignment, I picked up four top CSPs with comparisons of their functionality, cost, security, mobile access and customer support services. The four CSPs are Apple iCloud, Google, OpenDrive, and Amazon.
Undeniably, the internet technology grows exponentially since its inception. Currently, a new "trend" is emerging in the world of IT (Information Technology and Communication), this is cloud computing. This technology, based on the WEB 2.0, provides opportunities for companies to reduce operating costs by their software applications online. Various vendors like Google, Amazon, and IBM offer a wide range of cloud computing services (Schroth, 2007). This technology has just hatched, it is at the beginning of its operations but already several major players mentioned above adopt their own pioneering strategies that determine the use of cloud computing companies wishing to invest.
Cloud Computing is considered the latest buzzword in computing today. It describes a form of computing wherein services are accessed through the Internet on an as needed or pay-per-use basis. Some aspect of cloud computing is in use on a regular basis. Understanding this technology, its benefits, and underlying security risks are important for people in most of today’s technical areas. Because Cloud computing is still considered to be in its infancy, an introduction to cloud computing, defining its major components, with a focus on Software-as-a-Service (SaaS), is the foremost theme of this paper. There are three major elements of cloud computing - Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and
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.
Cloud computing comes in three distinct implementations or models, each with its own pros and cons. The advantage is that each can be tailored to meet a specific need. The three different implementations are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). In IaaS, an organization uses the cloud to provide virtual resources, such as storage space for data or online databases. Amazon’s Simple Storage Service (S3) is an example of IaaS, with customers utilizing the S3 cloud to store information. PaaS implementations run on top of IaaS, giving the organization flexibility to implement customized applications, such as specific portions of Google apps. Finally, SaaS is the transition to almost all operations to the cloud. In SaaS, a small blade system is used to connect to the cloud through an Internet connection where all the software and major computing power is stored. Instead of having an OS installed on each desktop system, the OS and everything else needed is stored on the cloud servers and accessed through a web browser or custom plug-in.

Cloud Computing is a new paradigm of large-scale distributed computing which is rapidly becoming one of the hottest topic among business organisations (Pallis, 2010), and represents a fundamental change in the way of Information Technology (IT) services are invented, developed, deployed, scaled, updated, maintained and paid for (Martson et al, 2011).
Cloud computing, in its most basic form, is “using computer services [such as computer and data storage, management and processing] that are delivered over a network” (Kim & Solomon, 2013, p. 189). For example, an organization may require a great deal of storage for their data but may not want to purchase the servers, the physical space for the servers, or the personnel to manage the infrastructure. Instead, they take advantage of the many cloud computing options and outsource their needs, hiring someone to do everything off-site usually with the goal of reducing their overall cost of ownership. As defined by the National Institute of Standards and Technology (NIST), cloud computing has five essential characteristics, three service models, and four deployment models (Mell & Grance, 2011) which will be covered, briefly, in the next few sections.
Cloud computing has rapidly increased their services for IT infrastructures solutions in the last years, reducing cost of investment of supplies and maintenance becoming a promising concept in the business and IT industry. The cloud provides shared data center, automatic upgrades, security and performance. However, cloud’s safety and standardization have been a challenge when different types of clouds need to be connected. Resource management issues as Quality of service (QoS) and the increasing of complexity and functionality failures are a constant in cloud computing environments, and should be considered by customer when looking for cloud solutions to adapt their organization’s requirements. This paper will explain the
Cloud computing is a web based utility model. The user does not need to maintain any infrastructure that is to be managed by the provider that is cloud provider. The cloud provides different solutions for the software, platform oriented and the infrastructure. There are three types of services offered which are classified as (IaaS) Infrastructure as a Service, Platform as a service (PaaS) and Software as a Service (SaaS). These services can be deployed by its cloud models that can be private, public, hybrid and community model.
Cloud computing provides online access to computer based services or resources to users where data is stored in a centralized network by grouping several remote servers. Cloud platforms which renders services includes IaaS (Infrastructure as a Service) for data storage, PaaS (Platform as a Service) for application development or deployment and SaaS (Software as a Service) for hosting software. Organizations using cloud based services can result in cost savings because they need not buy their own infrastructure or software and there is no need of hiring resources for maintain and upgrading it. By utilizing the cloud based services companies can take an advantage of utilizing the latest available technologies without
The largest Buzzword in emerging trends for the computer world is “Cloud”. Cloud computing in the future for data, services and platform. The concept of cloud computing is to make whatever aspect it is being used in available at all times and to act as a resource. Turning computing into a utility will transform how the IT industry uses services, designs hardware and uses network infrastructures. The term “Cloud” however has many meanings, but understanding what exactly is meant by cloud computing is the first step to
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.
cloud computing is making a quick revolution in information technology, and numerous specialists feel that cloud computing will be the following enormous thing. In this report, I look at the three vendors who are giving cloud administrations in present business sector and what are fundamental technologies they offered, and how they are securing their customer 's information in chapter-1. At that point I take a gander at given contextual analyses and portray the benefits that the cloud computing offered to those organizations in chapter-2. At last, I give answers for the given situations by utilizing AWS as a part of Chapter-3&4.
