Conversion to client/server systems from host‐centric systems can be accomplished with careful attention to planning and development procedures. A key component in a successful conversion is a customized definition of client/server which complements the organization’s mission. Another key component is the development of an infrastructure which includes hardware, software and people. The training of users and design personnel is crucial to successful conversion. Discusses definitions, strategies, hardware, software, and the pitfalls to be avoided.

The purpose of this paper is to discuss the latest information on cloud computing in a library context.

The paper adopts an investigative approach including literature review and vendor‐provided information.

Cloud computing is both a trend and technology to deliver software and hardware as a service, not as a product. It involves a centralized data center, virtual server space, and secure transfer of data over the internet. The alleged advantages of cloud computing include low cost to own (CTO), agile updates, openness, zero initial investment, just to name a few. Lately library system vendors have begun to deliver cloud computing options. For instance, Ex Libris will release Alma in early 2012. It is an Integrated Library System with a discovery layer based on cloud computing. Amazon (Elastic Compute Cloud called Amazon EC2) and other vendors also offer virtual servers for cloud computing and charge customers by hours, usage, and capacity. If this trend continues for the next several years, it is just a matter of time before librarians will face the decision as to whether they should move into compute cloud.

The paper discusses this new trend, focusing on the pros and cons of moving into cloud computing for libraries.

Presents major findings from an in‐depth multi‐company American study on the effective management of the distributed computing environment. The study, led by Cambridge Technology Partners, focuses on the management approaches that contribute to the greatest success in the client/server arena. Synthesizes the study’s broad findings into eight major areas of concern and focus for future distributed systems management.

Presents inexpensive ways to implement a virtual parallel computer with multiple Web servers. “Servlets” are used instead of CGI programs. Compares the multiple Web server model with a multiple‐client model. Experiments are conducted to test the performance of these two parallel systems. The performance of these two models is then compared. The advantages and limitations of these models are also discussed.

The purpose of this paper is to propose a model to map the on-premise computing system of the university with cloud computing for achieving an effective and reliable university e-governance (e-gov) system.

The proposed model incorporates the university’s internal e-gov system with cloud computing in order to achieve better reliability, accessibility and availability of e-gov services while keeping the recurring expenditure low. This model has been implemented (and tested on a university e-gov system) in the University of Kashmir (UOK); case study of this implementation has been chosen as the research methodology to discuss and demonstrate the proposed model.

According to the results based on practical implementation, the proposed model is ideal for e-governed systems as it provided adequate cost savings and high availability (HA) with operational ease, apart from continuing to have the necessary security in place to maintain confidential information such as student details, grades, etc.

The implication of this study is to achieve HA and to reduce the cost from using external clouds, mapping internal IT servers of the university with the external cloud computing services.

Because no established mapping model for universities has been provided for effective, low-cost, highly available university e-gov system, the proposed mapping model through this paper closes this gap and provides guidelines to implement a hybrid-mapped e-gov model for universities while keeping the recurring expenditure on cloud computing minimal. The paper provides the perceptions of its adoption at UOK for achieving high reliability, accessibility and uptime of its e-gov applications while keeping the recurring expenditure on cloud computing minimal.

Today, business organizations compete in the global marketplace. To compete successfully, organizations pursue the status of the world‐class organization (WCO). A WCO is defined as the best in its class, or as good as its best global competitor, in providing most value to the customer. The strategic pillars that enable an organization to become a WCO must be supported by effective information systems. Conventional information systems development approaches are not necessarily relevant for WCOs. Presents new approaches to developing the information for world‐class organizations.

Cloud Computing (CC) technology is getting implemented rapidly in the educational sector to improve learning, research and other administrative process. As evident from the literature review, most of these implementations are happening in the western countries such as USA, UK, while the level of implementation of CC in developing countries such as India is rare. Moreover, implementing CC technology in the educational sector require various decisions to be made by the managers of the Information Technology (IT) department such as selecting suitable deployment model, vendor providing cloud service, etc. in their respective university or institute. The purpose of this paper is to attempt to address one such decision. Since, different types of CC deployment are available; selecting a suitable one plays a key role, as it might have an impact on the requirements of various stakeholders such as students, teachers, administrative staff (especially the staff members in the IT department), etc. apart from affecting the overall performance of the facilities such as a laboratory. Naturally, a proper decision by analysing multiple perspectives has to be made while carrying out such strategic initiatives by any educational institute.

A case study methodology has been chosen as the research methodology to discuss and demonstrate the above decision problem that was faced in real time by one of the educational institutes in India, offering high-quality management education. The IT managers of this institute were planning to switch over to CC technology for the computer laboratory and they have to make a decision of choosing suitable alternative CC deployment models such as private cloud (PRC), public cloud (PUC), community cloud (COC), hybrid cloud (HYC), etc. by analysing and comparing them based on various factors and perspectives such as elasticity, availability, scalability, etc. Since, multiple factors are involved in making such a strategic decision, the most commonly used Multi-Criteria Decision Making (MCDM) model – namely, the Analytic Hierarchy Process (AHP) is used as a decision support during the decision making process.

The team of decision makers, who were planning to implement CC in the case institute, found that PRC is best as they believed that it would provide adequate cost savings, apart from providing necessary security to maintain confidential information such as student's detail, grades, etc.

The results obtained are based on a single case study. Hence, they cannot be generalized for institutions across educational sector. However, the decision making situation and understanding its impact on the stakeholders of the educational institute can be common across various educational institute.

Using a real-life case study of an educational institute, this paper presented a strategic decision making situation, which needs to be considered by the IT managers of the educational institutes when they decide to switch over to CC technology. Various criteria to be considered during the decision making process was identified from the literature review were identified and enumerated. These factors would useful for the IT managers of the different educational institute and they can suitably add or delete these decision criteria as per their requirements and situation at hand. Moreover, the algorithm of AHP, which was used as a decision support, was presented in a step-by-step manner, which should be beneficial for the practitioners to apply the same for similar decision making situations.

It is believed that this paper would be the first to report on a strategic decision of choosing the deployment model for CC technology especially in the educational sector. Similarly, this paper would also contribute to the field of CC, as it lists out the decision criteria that are to be considered for making the above decision, which has not got adequate importance. Lastly, this paper is also unique in the realm of AHP because application for a decision problem in the field of CC especially in the educational sector is least reported.

As businesses increasingly use electronic data processing (EDP) techniques to process their accounting systems, auditors must gather critical information more efficiently. Such tools and techniques as electronic data interchange, the Internet and other modern technological subjects signal the end of the traditional audit. Technology has made inputting information for transactions and events more simple ‐ and evaluating the related controls and results more critical. Accumulating sufficient evidence needed to construct an informed decision means understanding where to look for that evidence, what control procedures to consider and how to evaluate those procedures. The purpose of this article is to draw attention to these issues and the recently issued SAS No. 80, which offers auditors guidance to accumulate sufficient evidence to audit their computerized clients. We also address some issues auditors may face in evaluating the security control in their clients’ businesses.
