Cloud Computing Is A Web Based Utility Model

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 a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure. [1] Example: Google application engine, Software as a Service (SaaS) is

While it is true that cloud computing models can vary it all comes down to three components consisting of the Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These work to manage your cloud computing service level by way of the surrounding management layer.

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

Cloud computing has proven that it is a technology that is here to stay and has shown to be a powerful game changer in modern business. It is a key component in allowing a organization to operate in ways never before imagined; however, with any new technology it is important to be educated about the technology and situation to be able to effectively leverage for an advantage. Through discussion of the technology, combined with potential security issues, strengths and weaknesses, a more thorough understanding of cloud computer

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 is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure.[1] Example: Google application engine, Software as a Service (SaaS) where company host their data in cloud and user can access through internet. Example: Gmail, Facebook. Infrastructure as a Service (IaaS) is providing basic services. Cloud computing has four models first is public cloud services are available over a network that is open for

Technically, Cloud is as a term of a platform, it provides, configures and reconfigures servers while the servers could be virtual machines and physical machines. Additionally, Cloud is also as a term of applications that are described as to be accessible over the internet based on the support from powerful servers and large data centers. Therefore, Cloud is quite different from traditional computing paradigms because of its scalable. Cloud is an abstract entity to supply different levels of services. Shown by figure 1, Cloud is typically providing three types of services: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

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

To make it simple, cloud computing is a system for users store and access data or programs over the internet instead of individual hard drive. This cloud system is composed of three parts in terms of four important features, several service models and development models, details of those components will be explained in this report.

The popularity of mobile system with the headway in engineering, with the increment of Internet utilization, comprehensively reinvent the old idea of network computing system, to the new buzzword "Cloud computing". Cloud computing is a link way to the usage of Cloud which process by transmitting and receiving files in utilizing Internet. Most systems uses either of the three major models of cloud computing services on the market, which are software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS).

Cloud computing is used to connect ‘n’ number of computers to a single network and gaining different level of access across the world. It is used to reduce the IT infrastructure because it provides different type of services like servers, storage, databases, networking, software, analytics, and so on over the Cloud Computing. In present world we have different type of cloud computing like Amazon Web Services, IBM, and Salesforce etc. with different specifications which are required to others. Each service has its once implementation techniques to provide user friendly accessible.

1.Cloud Computing: Cloud computing is defined as the different services such as service, storage and applications are deliver to organization devices and computers through internet. There are mainly three types of clouds they are private public and hybrid and three services are offered by the cloud mainly Software as a service in which user rent access to software application functionally over the internet eg:ltu student mails .,

Cloud computing is a part of internet growth, it’s the next generation of internet. Cloud computing deliver everything –computing resource, infrastructure, application, and business process to personal collaboration – and can be access as service wherever and whenever through various devices. The cloud itself is a set of hardware, networks, storages, services, and interface that enable to delivery of computing as services based on user demand. (Hurwitz, J, 2009)

Over the years, computing concepts changing from distributed to parallel to grid to cloud computing. The evolution of computing is shown in Figure 1. Now a day, people choose cloud computing because of the advantages they get from cloud computing. The advantages are scalability, reduced management efforts, on-demand resource allocation and flexible pricing model (pay-as-you-go). Cloud computing has three service models: Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS). The basic concept of cloud computing and services is shown in Figure 2. Example of application or services using cloud computing are Microsoft OfficeLive, Dropbox, CluodNumbers, Google AppEngine, SalesForce
