Hosting Case Study

The cloud can provide swift access to malleable and low budget IT resources. With the use of cloud computing, you are not required to make big direct investments in hardware and spend a lot of time on managing that hardware and associated services. Cloud Computing compromises a comprehensive set of on-demand services, such as global computing, storage, database, analytics, application, and deployment services. These services will assist an organization move quicker, reduce IT costs, and scale systems. Cloud Computing has three key categories, they are usually referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Mobile as a Service (MaaS) and Software as a Service (SaaS).

Cloud Computing has very many benefits especially for the businesses. First, it leads to reduced technological costs. This is because unlike purchasing of a system which is expensive, the payment is only made upon usage and thus making it cheap (Marston et al 2011). Secondly, there are much reduced

Cloud computing offers many advantages to both end users and businesses of all sizes. The advantages of cloud

Some of the immediate advantages of cloud computing involve lower equipment costs, scalability and online collaboration. A company can take advantage of cloud services without major upgrades to their existing equipment and infrastructure. Using a web browser, most company employees can access “Software as a Service” or SaaS. This service runs on a cloud provider’s server with no installed on the local server within the organization.

There are various reasons why SaaS is useful to associations and individual clients alike. No extra equipment costs; the handling force needed to run the applications is supplied by the cloud supplier. No starting setup costs; applications are prepared to utilize once the client subscribes. Pay for what you utilize; if a bit of programming is required for a constrained period then it is paid for over that period and memberships can as a rule be ended whenever. Utilization is adaptable; if a client chooses they require more capacity or extra administrations, for instance, then they can get to these on interest without expecting to put in new programming or equipment. Redesigns are mechanized; at whatever point there is an upgrade it is accessible online to existing clients, regularly gratis. No new software will be needed as it regularly is with different sorts of utilizations and the upgrades will more often than not be sent naturally by the cloud supplier.

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 able to offer a distinct advantage to companies willing to move into this growing arena. This is not without its drawbacks. Even in the definition of Cloud Computing by the National Institute of Standards and Technology, (NIST) clear advantages exist. The definition includes the following terms: on demand self-service, ubiquitous network access, location independent resource pooling, rapid elasticity and measured service.

The main aim of cloud computing is to save money in the business by allowing online provisioning of IT resources on demand. The IT personnel can now focus more on core business capabilities rather than maintaining the infrastructure. Cloud services are instantly created and automatically provisioned as and when needed which allows to totally reducing the cost of ownership.

In the last ten years the most popular pricing model for SaaS within consumer and enterprise firms is freemium. Although there are many definitions and alliterations, basically this represents a business model that

SaaS (Software as a Service) - On-demand software applications through a web browser, avoiding a need of full scale installation, maintenance and monitoring of software application platforms and its infrastructure.

There are different types of cloud computing services available on the market which falls into one of the following categories.

SaaS is an application level cloud service that provides interface software and database. User simply accesses the software running on the back-end server of the cloud clients such as web browsers, emulators and mobile web browser, and use the services. The best example of this services is a web-based email service. Users are able to send or receive emails from web browser remotely without installing or running email software on his/her device. The essential software are running on the Cloud Computer which allow user to access the desire resources from any supported devices.

Software as a Service (SaaS), sometimes referred to as "on- demand software" is a software delivery model in which software and associated data are hosted on the cloud. SaaS is typically accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement.

The popularity of SaaS systems is based on the positive impact it has on availability, performance and security. As an alternative to traditional, on-premise hardware and software, SaaS solutions provide real advantages and not just change in style. Organisations that adopt SaaS systems can enjoy:

Cloud Computing is the use of common software, functionality or business applications from a remote server that is accessed via the Internet. Basically, the Internet is the "cloud" of applications and services that are available for access by subscribers utilizing a modem from their computer. With Cloud Computing, one simply logs into desired computer applications - such as sales force or office automation programs, web services, data storage services, spam filtering, or even blog sites. Generally, access to such programs is by monthly or annual paid subscription. Through Cloud Computing, businesses may prevent financial waste, better track
