...facing cloud computing making it difficult to maintain data security and privacy, support data and service availability and demonstrate compliance. These issue also make cloud vulnerable to exploitation by attackers. The three cloud services models used today are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).Iaas provides the most dynamic functionality since it is based as the underlying layer in cloud. It widens the resilience for users to design a practical environment that includes virtual machines running with different operating systems. This may pose as a vulnerability since an attacker could lease these virtual machines, analyze their configurations, find their vulnerabilities, and attack other customers’ virtual machines within the same cloud. Brute force and Distributed denial of service (DDoS) attacks could also take place in Iaas as it provides a platform for use of virtual machines. Data loss is major security risk of the three cloud computing service models. In SaaS, consumers and business data is stored at a data center, in PaaS, application developers use data to test software integrity during the system development life cycle and in IaaS cloud models, data is stored in the drives of virtual...

...Cloud Computing Introduction Information technology has been infiltrated into our daily life due to the advent of technology. In business setting, the usage of information technology is omnipresent and information system is widely used among entities. For information system, cloud computing is one of the popular applications for businesses because it can reduce IT cost at the same time facilitating a company in various perspectives. In this essay, a fast-growing company called Airbnb, adopting concept of collaborative consumption, will be analyzed to demonstrate the use of cloud computing. Background Airbnb is an American company founded in 2008, an online platform for people to rent out, list, discover, and book lodging, including private rooms, entire apartments, castles, boats, private islands and other properties around the world. Through online or mobile phone, a transaction can be done conveniently (Airbnb, Inc., 2014). Airbnb has expanded to host more than 500,000 listings across 192 countries since launched in 2008 (King, 2013) and has now served 9 million guests in the fifth year (Lawler, 2013). However, one year after launched, It experienced service administration challenges because of its original cloud computing provider, therefore, Airbnb decided to migrate nearly all of its cloud computing functions to Amazon Web Services (AWS) (Amazon, 2014). Benefits for adopting cloud computing Definition Cloud computing is a type of computing...

...organization (Shehab et al.). When implemented correctly, ERP is a high-cost investment but also offers high return as it enables companies to centralize their day-to-day operations in real time. Cloud computing technology enables convenient, on-demand network access to a shared pool of configurable computing resources that can be provisioned and released with minimal management effort or service provider interaction (Mell et al.). There are three service models in cloud computing: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). SaaS is capability provided to the consumer to use the software provider's applications running on a cloud infrastructure, with applications accessible from various client devices (Mell et al.). PaaS is capability provided to the consumer to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider (Mell et al.). IaaS is capability provided to the consumer to provision processing, storage, networks, and other fundamental computing resources in which the consumer is able to deploy and run arbitrary software (Mell et al.). For the purposes of this paper, we will focus on a specific module of ERP running on a specific model in cloud computing. Due to the immense scope of ERP and cloud computing, it is nearly impossible for us to capture the entirety of ERP on all three...

...Cloud Computing for Education and Learning: Education and Learning as a Service (ELaaS) Mohssen M. Alabbadi Computer Research Institute (CRI) King Abdulaziz City for Science & Technology (KACST) Riyadh, Saudi Arabia Alabbadi@kacst.edu.sa Abstract—Cloud computing, despite its hype, is being widely deployed, with its dynamic scalability and usage of virtualized resources, in many organizations for several applications. It is envisioned that, in the near future, cloud computing will have a significant impact on the educational and learning environment, enabling their own users (i.e., learners, instructors, and administrators) to perform their tasks effectively with less cost by utilizing the available cloud-based applications offered by the cloud service providers. This paper discusses the use of cloud computing in the educational and learning arena, to be called ‟Education and Learning as a Service” (ELaaS), emphasizing its possible benefits and offerings. It is essential for an educational and learning organization, with its budget restrictions and sustainability challenges, to use the cloud formation best suited for a particular IT activity. The Jericho Forum proposes a cloud computing formation model, called the Cloud Cube Model (CCM), which is based on 4 criteria. To preserve the symmetry of the cube, a new cloud computing formation model, called the Complete Cloud Computing Formations (C3F), is proposed. The IT activities in the educational and learning organizations are...

What were the problems faced by Income in this case? How were the problems resolved by the new digital system? Problems: (1) The old HP 3000 mainframe frequently broke down, and backup or reconciliation would be needed. However, If daily backup was not completed, the affected day’s data would be lost and cost months to do reconciliation. (2) The 1980s COBOL programs broke multiple times, halted the systems and caused temporary interruptions, and it took IT team long time(from several weeks to months) to launch new products. (3) Transaction processing for policy underwriting was a batch process and information was not available to agents and advisors in real-time. (4) Various departments did not have up-to-date information and had to pass physical documents among each other. How were the problems resolved: Income switched to the Java base eBao LifeSystem from eBao Technology. The new system seldom broke down, and it enabled the IT team to launch a new product only in a few days by using the table-driven rule-based product-definition module; plus, the real-time hot backup disaster-recovery 1/9 宋蕊廷 201311034009 ASSIGNMENT 1: MANGAGEMENT INFORMATION SYSTEM center helped the company get real-time...

...McMann Cars Corp. PART I Identification and prioritisation of the problems facing the organisation. A rationale/justification needs to accompany your identification of problems. Your analysis should examine the major issues or problems currently facing the situation. Based on the evidence supplied in this part, we identified that the organisation is facing six problems effecting directly to business, those issues are communication, data management, security and fragmentation network operation system, supply chain management, obsolescence system, and weather forecasting. Communication issues This is the prioritisation problem faced by the company, there are a plenty of issues which the organisation is facing within this trouble. The very first complication is the geographical dispersion of offices in Europe countries, so that senior managers have to travel around divisions to communicate directly. As a consequence, money and time are being spent inefficiently. In addition, the lack of good intranet with compatible email system is also suffering to internal communication: current systems are introducing unnecessary redundancy which offers incoherent association with other branches. Furthermore, the status of real-time correspondence is not supporting effectively in connecting with suppliers and sub-contractors, this leads to the problem of missing project timeline. Obsolescence systems issues The loss and corruption of data has been experiencing during a period...

...head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses. • applications can be developed upon and deployed. It can reduce the cost and complexity of buying, housing, and managing hardware and software components of the platform. Infrastructure-as-a-Service (IaaS) enables a software deployment model in which the basic computing infrastructure of servers, software, and network equipment is provided as an on-demand service upon which a platform to develop and execute applications can be founded. It can be used to avoid buying, housing, and managing the basic hardware and software infrastructure components. 1. Introduction Cloud computing has been defined by NIST as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction [45].

...Information Technology and Management Science doi: 10.2478/v10313-012-0013-8 2012 /15 Cloud Computing Evaluation Based on Financial Metrics Maksims Kornevs1, Vineta Minkevica2, 1-2Riga Technical University, Marcus Holm, Cisco Systems Abstract – Interest in cloud computing is growing, and, as a result, there is much information about it – both positive and negative. On the one hand, cloud computing saves money because it does not require IT infrastructure, servers, and it is very scalable. On the other hand, it might lead to financial loss due to security risks, possible data access problems, data privacy policies, etc. Therefore, cloud computing evaluation based on financial metrics is proposed in this article. This paper consists of four major sections. The first section is a literature review of cloud computing and its types. The next section describes some common financial metrics such as CBA, ROI and TCO and describes how they might be applied to evaluate cloud computing. The third section proposes evaluation strategies, and the last section contains the evaluation of a series of cloud computing projects based on chosen evaluation strategies, and results are verified based on expert opinion. Keywords – cloud computing, CBA, ROI, TCO, ROC computing as “a model for enabling convenient, on-demand network access to a shared pool of configuration computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction”...

...I. INTRODUCTION 1.1 Introduction Over the years many organizations have invested in massive in-house computing capacities and specialized Information Technology (IT) staff around the world in order to support their primary business processes or to achieve a competitive advantage. According to Porter and Millar IT creates competitive advantage by giving companies new ways to outperform their rivals. To gain competitive advantage over its rivals, a company must either perform these activities at a lower cost or perform them in a way that leads to differentiation and premium price (Porter & Millar, 1999). These days, organizations are looking for IT to operate more efficiently and help to reduce the overall costs. The concept of outsourcing has contributed to this development by transferring entire business functions to an external service provider. A recent phenomenon in the domain of outsourcing is called Cloud Computing. “Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically re-configured to adjust to a variable load (scale), allowing also for an optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the Infrastructure Provider by means of customized SLAs” (Vaquero, 2009). The arrival of the Internet has accelerated the commoditization of IT by providing a perfect delivery...

This industry, along with DVD rentals (both from online providers such as Netflix, and cable services such as On Demand and Pay-Per-View), is part of the larger industry of “watching movies in the home.” However, since Netflix is already positioned in this market, with its online DVD rentals, we will examine the smaller 5 portion of the market that is streaming online movies. This business is too closely related to the movie downloading service to be considered as a separate market. Threat of Potential Entrants Today, internet video rental industry is very profitable and still has a very good develop prospect. After Netflix’s success, the whole video industry starts to change gradually, and more and more people start to consider entering this field. However, for most of those potential entrants, this industry has some big barriers to entry. First of all, the service in this industry is already very complete. With its seven-year-development...
