Cloud Computing Service Models Within Public Sector

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

This research paper tackles the issues that faces Cloud Computing today and gives the experts and industry’s point of view on the matter. The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks

SaaS – Software as a Service – Users on the service are given access to the application’s software and databases, cloud providers manage the infrastructure and platforms that run the application. “On demand”.

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.

The information technology industry is growing at a rapid pace. Every business entity needs some form of IT support to ensure that business operations are continuously running. As an entity grows in size and revenue, the information system needed to support the entity needs to grow as well. Some businesses may not have enough resources to accommodate this expansion. Their building may be too small or they cannot afford to purchase the equipment. When this is the case, an organization will choose to migrate their network infrastructure to a cloud computing environment. Cloud computing allows for a company to implement a large scale network without having to incur expenses for modifying the building infrastructure. Cloud

The SaaS model allows the user to use an application provided by the cloud provider, like a software application installed with the only difference that the application is delivered through internet. Many companies such as Microsoft, Autodesk and Adobe are moving towards this concept that

The term ‘cloud computing’ gets tossed around in media and business settings, and while everyone seems to know generally what it is, not everyone is aware of how to use it, much less how to implement it in a safe way that still enables it to provide the full benefits of storing data in the cloud versus storing and managing it on-site. Cloud computing has many benefits for businesses, such as allowing them to store information and be managed by an outside company, which eliminates the cost and effort of a company having to buy servers, install and configure them, and then hire IT staff to continue to maintain them. According to a study of over 1,300 U.S. and U.K. businesses, 88 percent reported that they saved money using cloud services,

Cloud computing is revolutionizing every aspect of Information Technology. Many businesses and organizations rely on their own internal IT departments to operate their specific applications, databases, and programs. Cloud allows them to cut ties with in-house servers and receive their complete IT needs from an external Cloud provider. Cloud is faster and easier to use than traditional infrastructures, often making it more cost effective. Several private companies have already switched to Cloud and the federal government has ordered every agency to identify at least three “must move” services and shift them to Cloud by mid 2012. (Scharff, 2011)

SaaS applications offer wide range of configuration options and development environments that allows clients to set up their own additions and modifications.

IT industry being one of the major development areas, many people choose their career in it. To support all range of industries i.e., from small scale to large scale, cloud computing emerged which reduces the efforts both physically and with regard to capital investment.

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

Cloud computing has now become a competitor to traditional IT because of how cheap it is and that it is based on “pay-as-you-go” service just like electricity or gas. There has been a great increase in the migration of businesses into cloud. Cloud has its down side but the advantages are higher and almost negate the downsides. Some of these advantages are resource availability on demand, pay as you go, hardware utilization is better and more efficient, no in house losses with respect to hardware and since there is no hardware involved the maintenance is low too. Cloud computing is drawn-out from distributed computing,

For example, services like WFS will now be Software as a Service (SaaS) as they offer functionality, such as spatio-temporal query. Similarly, processing services like WPS (Web processing Services) where the computation resources are provided via PaaS (Platform as a Service) and IaaS (Infrastructure as a Service). The benefits of using a cloud computing infrastructure from a networking perspective are standardized service interfaces between different clouds; the existing publish-find-bind pattern for service interaction can be reused.

PaaS is a development platform supporting the full “Software Lifecycle” which allows cloud consumers to develop cloud services and applications (e.g. SaaS) directly on the PaaS cloud. Hence, SaaS only hosts completed cloud applications whereas PaaS offers a development platform that hosts both completed and in-progress cloud applications and this is the only difference between SaaS and PaaS. It provides the Run-time environment for application,development and deployment tools.
