Secure Data Sharing in the Cloud
Danan Thilakanathan, Shiping Chen, Surya Nepal and Rafael A. Calvo

1 Introduction
Cloud systems [1, 2] can be used to enable data sharing capabilities and this can provide an abundant of benefits to the user. There is currently a push for IT organisations to increase their data sharing efforts. According to a survey by InformationWeek [3], nearly all organisations shared their data somehow with 74 % sharing their data with customers and 64 % sharing with suppliers. A fourth of the surveyed organisations consider data sharing a top priority. The benefits organisations can gain from data sharing is higher productivity. With multiple users from different organisations contributing to data in the Cloud, the time and cost will be much less compared to having to manually exchange data and hence creating a clutter of redundant and possibly out-of-date documents. With social networking services such as Facebook, the benefits of sharing data are numerous [4] such as the ability to share photos, videos, information and events, creates a sense of enhanced enjoyment in one’s life and can enrich the lives of some people as they are amazed at how many people are interested in their life and well-being. For students and group-related projects, there has been a major importance for group collaborative tools [5]. Google Docs provides data sharing capabilities as groups of students or teams working on a project can share documents and can collaborate with each other effectively. This allows higher productivity compared to previous methods of continually sending updated versions of a document to members of the group via email attachments. Also in modern healthcare environments, healthcare providers are willing to store and share electronic medical records via the Cloud and hence remove the geographical dependence between healthcare…...

...Use of Storage as Service for Online Operating System in Cloud Computing Piyush Saxena M.Tech (CS&E) Amity University, Noida, India Satyajit Padhy M.Tech (CS&E) Amity University, Noida, India Praveen Kumar Assistant Professor, Amity University, Noida, India Abstract— Cloud computing has made it possible to make system boot using online operating system thus saving both primary and secondary memory because the data is on centralized data centre located outside the organization which is highly secure. It is not in computer memory so that it can be accessed anywhere. It also saves money as one doesn’t need to buy any expensive hardware to access the particular software in your computer. Cloud computing is a highly scalable pay-per-use IT capabilities. Now a days, software is very much expensive which even MNC’s don’t want to purchase it due to various factors which is:-Not reliable, Highly expensive which is very costly to install it on 1000’s of computers, If any error occurrence it takes 1-2 days to solve which is a big loss for organization. So, here is the simple solution i.e. cloud computing which makes organization more productive due to low cost of software with high-end features, highly reliable, low maintenance cost, problems solving immediately and Highly secure.

D1 Evaluate the Distribution Systems in Delivering Goods and Services for a Selected Organisation

...D1 Evaluate the distribution systems in delivering goods and services for a selected organisation This assignment will be discussing about when I was working as a logistics manager for Morrisons and we will be talking about how Morrisons distribution system works and evaluating the system. Morrisons' market share as of August 2013 was 11.3%, making it the smallest of the "Big Four" supermarkets, behind Tesco (30.1%), Sainsbury's (16.6%) and Asda (16.4%), but ahead of the fifth place Co-operative Group, which had a share of 4.4% - There is currently 569 stores across the UK and this means that the distribution system must be effective and be able to deliver goods to the Morrisons stores in time. What is a logistics manager A logistics manager is a type of manager which overlooks the storage and movement of the goods and supplies of different businesses. They are relied upon for all of every aspect of transporting the goods and the burden of delivering goods on time is their job. People in the position of logistics managers arrange the movement of raw materials and also finished goods. The materials go to different processors and factories which manufacture goods. The managers also have to organise the arrangements of storing goods in warehouses and how they get their etc. The term "logistic manager" originally referred to a military position. Military managers were in charge of making sure far-flung military groups had food and......

...transmitted easily from one place to another. Cloud Computing is one of the proofs of technology improvement. This report explains about cloud computing, benefits and drawbacks of cloud computing and impacts of cloud computing on accounting profession. What is Cloud Computing? Cloud computing was originally known as a bunch of combined services, technologies and activities. Cloud computing was also regarded as a collection of technologies (Rountree and Castrillo 2014). The name CLOUD is used because it can FLOAT ABOUT among specific servers and the specific server is not probably known by the users (Slahor 2011). The National Institute of Standards and Technology (NIST) came up with a formal definition which basically includes three main components: five key cloud characteristics, four cloud development models and three cloud service models. Not all the web-based applications are cloud applications. There are some specific characteristics of the cloud. The NIST defined that there are five key cloud characteristics: on-demand self-service, broad network assess, resource pooling, rapid elasticity and measured service. Organisations use different cloud computing models in order to meet their own requirements as to what services they want to assess from the cloud and how much control they want to have over the environment. Accordingly, four development cloud models are available: public, private, community and hybrid. Besides, Cloud Computing provided three broad categories of......

Relationship Between a Financial System or Function and Other System or Functions in an Organisation

...1.1 Finance plays a key role in the functioning of any organisation because a steady flow of funds is required to make planned expenditure for delivering products and services and the sale of these products and services generates the necessary funds to make a profit. Any activity undertaken by any of the other departments without proper financial consideration can have a detrimental effect. For instance, if the sales team decides to offer extended credit or discounts to increase sales, this will affect cash flow and finance will not be able to collect cash for the business when the need arises. Similarly, purchase may decide to pay suppliers quickly or place bulk orders in order to avail a discount, but there may not be sufficient funds available immediately. This may affect relationship with the suppliers. The financial situation of the company inturn dictates activities of the other departments. For example, if there is a shortage of funds with the finance department, the sales team may not be able to offer prospective customers attractive discounts and extended credit, thereby making the competitors’ offer more attractive. Shortage of funds may also affect marketing thereby reducing overall income. Also prioritisation of planned projects will be required and this may affect overall strategy of the company. Hence a two-way dependence is observed. In order to avoid such problems, it is therefore important to have effective communication between the finance and other......

...White Paper: Introduction to cloud computing The boom in cloud computing over the past few years has led to a situation that is common to many innovations and new technologies: many have heard of it, but far fewer actually understand what it is and, more importantly, how it can benefit them. This whitepaper will attempt to clarify these issues by offering a comprehensive definition of cloud computing, and the business benefits it can bring. In an attempt to gain a competitive edge, businesses are increasingly looking for new and innovative ways to cut costs while maximising value – especially now, during a global economic downturn. They recognise that they need to grow, but are simultaneously under pressure to save money. This has forced the realisation that new ideas and methods may produce better results than the tried and tested formulas of yesteryear. It is the growing acceptance of innovative technologies that has seen cloud computing become the biggest buzzword in IT. However, before an organisation decides to make the jump to the cloud, it is important to understand what, why, how and from whom. Not all cloud computing providers are the same. The range and quality of services on offer varies tremendously, so we recommend that you investigate the market thoroughly, with a clearly defined set of requirements in mind. Rob Lovell, CEO ThinkGrid What is ‘cloud computing’? Many people are confused as to exactly what cloud computing is, especially as the term can......
