Cloud Computing Essay

Since cloud environment does not reside in a capital facility, there is a substantial saving of the time and space. Also, it provides users access only to the resources they need for a particular task. This prevents them from paying for idle computing resources. Besides, there are competing providers for this service and an organization can always shift its business to another company offering better service or lower price. In terms of statistics, we spend $6,000 per month to update software, maintain our computer lab, and pay our employees. However, implementing a cloud computing with a constructing price of $2800 will incur a cost as low as $249 per month (Hinchcliffe 2009).

Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any

SaaS is generally acknowledged to have been acquainted with the business world by the Salesforce. Customer Relationship Management (CRM) item. As one of the soonest contestants it is not amazing that CRM is the most famous SaaS application range, however, email, budgetary administration, client administration and cost administration have likewise gotten great up

Cloud computing is provided by an outside organization; it takes the place of an existing system, usually an internal network, and moves it to a web based service where all information in the company will be processed and stored. Internal IT infrastructures can be costly due to maintenance and personnel. Cloud computing reduces costs by removing the need for an internal system and the people to run it.

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

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”.

With cloud computing, you no longer have to select, implement and manage back-end IT infrastructure directly, the infrastructure or service is delivered through a Web portal. Now, the data can be easily copied over to a cloud storage provider rather than sitting at a second site. And, all that is being paid for is the amount of resources consumed. In addition, cloud service providers also provide more than just online storage. The cloud provides computing capacity as well as storage. Therefore, the data can be manipulated and processed remotely. Thus, it requires fewer (on-line) servers and uses less energy than on-premise systems.

The word "cloud" is used to represent the internet and other communications systems. Cloud computing is the result of an evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing in the past, telecommunications companies mainly gave simply dedicated, point-to-point data circuits to their users. Starting from the 1990's, virtual private network services was included in their contributions. It made the telecommunication companies offer equally improved services whereby cutting down on cost as well as using resources effectively.

The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centres all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centres are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Cloud computing means on demand delivery of IT resources via the internet with pay-as-you-go pricing. Cloud computing is a virtualization based technology that reduces the cost of IT infrastructure. It provides a solution of IT infrastructure at low cost. It also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand.

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

The term cloud computing was first coined in 1996. However, the idea of sharing computing resources was conceived in the early 1970’s. Cloud refers to an agglomeration of objects, and it is used in cloud computing to refer to a set of things that are used together. In 1977, ARPANET used a cloudlike logo in referencing their network that had interconnected a variety of computer resources. A cluster of servers in the company’s premises looked like a cloud. Their server was circular, and the agglomeration of the servers ended up looking like a crowd. In 1981 CSNET another predecessor also used a cloud symbol for their computing components.

SaaS is a method of software that allows data to be accessed from any device with an internet connection. In the web-based model,

Cloud computing is a model for allowing convenient on-demand access from anywhere to a shared pool of computing resources. These can include servers’ storage, networking, applications, and services that can be rapidly and easily provisioned and released.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. SaaS is closely related to the ASP (application service provider) and On Demand Computing software delivery model
