Delivering computer solutions has changed radically over the past thirty years from centralised mainframe computing to distributed client-server solutions. The consumption of Information Technology and Services (IT&S) has been accelerated by advances in network performance and facilities, consumerisation, and most notably through the adoption of Internet services. Business applications have also gone through a similar change from bespoke in-house mainframe systems to packaged products, and more recently, to distributed application frameworks (as seen on the iPhone). The method of purchasing and contracting support for these systems has not kept pace with this complexity. Initially, customers with in-house operational and development capabilities purchased hardware, software and maintenance. In many cases this is now done on behalf of a customer by a systems integrator or outsourcer. Businesses however, have high expectations on IT and its ability to solve today’s problems quickly. This has led to a number of rapid development and project management methodologies, risk-reward arrangements and an erosion of the professional standards and quality of service once commonplace in the mainframe era. There is a clear disconnection between the static world of trustworthy IT solutions and the dynamic needs of today’s modern business environment. This drives the customer to question their “time to market” options, the cost legacy within the business and the value for money they receive from their IT solution. Customers believe they pay for IT functionality that they seldom use or appreciate. Their conclusion is that the IT services provided to the business do not meet the real day-to-day business challenges and often block the respon... ... middle of paper ... ...010 .

Virtualization is a technology that creates an abstract version of a complete operating environment including a processor, memory, storage, network links, and a display entirely in software. Because the resulting runtime environment is completely software based, the software produces what’s called a virtual computer or a virtual machine (M.O., 2012). To simplify, virtualization is the process of running multiple virtual machines on a single physical machine. The virtual machines share the resources of one physical computer, and each virtual machine is its own environment.
In his 2003 article ‘IT Doesn’t Matter’, Nicholas Carr charts the evolution of Information Technology from the invention of the microprocessor in 1968 to present day omnipresence of IT solutions. His bone of contention with IT is not concerned with its widespread presence, but the magnified costs involved in the upkeep of IT infrastructure. He wants to bulldoze the myth that increased IT spending will culminate in higher returns and better profits. Acknowledging that though “Information technology has become the backbone of commerce” (Carr, 2003), he notes that its omnipresence works against its strategic advantage.
Virtualization is nothing but the simulation of many virtual machines on single computer hardware environment by using virtualization software such as VMware. Virtualization software is installed on computer system an...

Cloud Computing is an up and coming strategy that could create millions of jobs while allowing companies to become more profitable. How does Cloud Computing work? The basis of Cloud Computing is having data, software, platforms or networks stored and executed by an outside source and then streaming the output to your electronic device.(McKendrick, J. 2012 march 3) In this paper I will address the following three topics: the history and basis of Cloud Computing, the three main features of Cloud Computing, and the three network types used of Cloud Computing.
The term “Cloud” is very popular among entrepreneurs and marketers, but it simply means the wonders of Internet. Cloud computing shares the same concept as utility computing, in which all the computers are connected through a network and shared computing resources, such as computation, storage and services, over the network. Typically, there are 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 a relatively new technology that allows data to be stored, distributed and manipulated with greater ease than ever. As described by Gurjar and Rathore (2013), the “Cloud is a large pool of easily usable and accessible virtualized resources. These resources can be dynamically reconfigured to adjust to a variable load, allowing also for an optimum resource utilization” (p. 1). By moving data, documents and media to the Cloud, the potential for business efficiency and productivity increases and anyone with internet can take advantage of the benefits. As with anything, it is important to understand the risks and benefits in order to weigh whether or not moving to the Cloud is the best move for the business. Some companies, like Lavu, an iPad based point of sale system, operate solely on the Cloud. Without Cloud computing capability, some organizations would not exist.
Cloud computing is sort of like the first computers come full circle – in the early days of computing, users at terminals with no computing power to speak of made use of the number-crunching capabilities of mainframes in a shared fashion – in fact, the model of computer use was called “time-sharing.” As the personal computer grew in power and capabilities while also becoming a cheap...
Most organizations today are moving to client server architectures. Client server attempts to balance the processing between the client and the server by having both do some of the logic. In these networks, the client is responsible for the presentation logic, while the server is responsible for the data access logic and data storage. The application logic may reside on the client, on the client, or on the server, or it may be split between both. There are many ways in which the application logic can be partitioned between the client and the server.

Evolution of cloud computing over the past few years is potentially one of the major advances in the history of computing. Many computing applications are general-purpose in nature, and therefore offer tremendous economies of scale if their supply can be consolidated (Marston, Li, Bandyopadhyay, Zhang, & Ghalsasi, 2011).
Cloud computing is the progression of other computing technologies such as paral-lel computing, distributed computing, and grid computing. Its main principle is to disseminate the computing grind stones to distributed computers. Majority of us still use the PC’s and laptops to cache the data and files, sharing of data and files, and to send emails. If our pc’s diverse...
Once users register themselves in the cloud, they have an easy access to information and content using mobile devices from anywhere with an internet connection. The cloud can significantly lower the expenses for using Information Technology (IT). Traditional desktop software costs users and companies a lot in terms of finance and in adding up the licensing fee for multiple users. However, cloud computing providers share their complex infrastructures and servers, as well as offer to maintain and upgrade their services. Users only pay for the storage they use and they do not need to take additional efforts to maintain and upgrade their applications, which saves them money. There are one-time payment, pay-as-you-go and other scalable options available, which makes it very reasonable for individual users and the company in question. This is available at much cheaper rate. Plus, Services in the scalable systems of the clou...
Computer Economics, a research and consulting firm, surveyed 209 IT organization worldwide regarding their IT investment plans. The leading trends “were identified as low risk/high reward based on their cost predictability and their positive return on investment for organizations within two years’ time.” CRM tops the list for 2014 (Mackie, 2014)
Effectively integrating information technology (IT) into an organization’s business processes is critical if the organization wants to increase productivity and remain profitable. IT includes items such as the systems software, application software, computer hardware, and the networks and databases that help manage the organization’s information. When implementing quality standards and processes that are forever changing in the IT world, organizations must balance these changes while continuing to rapidly implement new systems technologies in order to stay competitive.
