SDS becomes more and more popular, and several companies have announced their product. But the generic standard still has not appeared, most products are only appropriate for their devices and SDS just can integrate a few storages. In this thesis, we will use the Open Stack to build and manage the cloud service, and use software to integrate storage resources include Hadoop HDFS, Ceph and Swift on...
In this research, we built the fire fighting support system for supporting the fire fighting of the volunteer fire company. This system is the mobile application based on Web-GIS. By using this system, the fire corps volunteers can confirm the fire fighting water sources around the fire site in real time. In fire fighting, secure of the fire fighting water sources are the most important. Therefore,...
The introduction of bring your own device (BYOD) policy in the corporate world creates benefits for companies as well as job satisfaction for the employee. However, it also creates challenges in terms of security as new vulnerabilities arise. In particular, these challenges include space isolation, data confidentiality, and policy compliance as well as handling the resource constraints of mobile devices...
Knowledge Management (KM) systems can be difficult to install. It can be even more difficult to ensure its use by employees. We present two case studies -- one that failed and one that succeeded. The first case study examines the efforts to implement and use a KM system at a tax firm, and the challenges encountered that defied resolution, leading to the KM system's demise. The second case study examines...
Complex data queries, because of their need for random accesses, have proven to be slow unless all the data can be accommodated in DRAM. There are many domains, such as genomics, geological data and daily twitter feeds where the datasets of interest are 5TB to 20 TB. For such a dataset, one would need a cluster with 100 servers, each with 128GB to 256GBs of DRAM, to accommodate all the data in DRAM...
The literature on cloud computing has been dominated by examples and issues from small to mid-size companies. This paper reports on a large scale cloud pilot project within the petrochemical industry, perhaps one of the biggest examples of cloud computing pushing the boundaries of what you can do with sensitive data. The study aimed to explore the challenges and practicalities of initiating and evaluating...
Domain Name System is a component of the Internet Infrastructure shortly referred as DNS. DNS provides simple service for lookup and translation of URL into IP addresses and IP addresses into URL. However, due to the enormous scale of the Internet, the DNS also has grown tremendously, leading to security concerns stability and reliability. Cloud computing with its superior features of availability...
Cloud-assisted mobile health (mHealth) monitoring is a revolutionary approach to provide decision support in the health care sector. It employs not only mobile communications but also cloud computing technologies to deliver timely suggestions. Its main objective is to not only improve the quality of healthcare service but also to decrease the healthcare expenditure. In spite of the benefits it offers,...
Companies nowadays are widely adopting cloud computing. One important problem encountered to efficiently adopt public IaaS clouds is wasting leased computational resources, which remain active if no policy is established to implement elasticity according to the demand. As a consequence, the cloud use becomes more expensive than expected, leading to higher costs that may turn the company business unattractive...
It has become common to operate an IT system where client computers in offices in a country access cloud computers in another country via the Internet. On the other hand, in some countries including China, network communication is often shut down by governmental bodies, in addition to network outage caused by network attacks. In the presence of these intentional or deliberate interruptions, users...
In this paper, a novel measurement data management system, based on cloud technology, is proposed. The system aims at maximizing the potential of the information assets of large electronic manufacturing companies through the collection, management and analysis of the so called Big Data generated by means of test processes, performed during the life-cycle of the products.
In today's world, businesses are under enormous pressure to reduce operational and capital expenditures related to their use of communications technologies. Businesses are also looking into re-organizing to work more collaboratively and efficiently. Unified Communication (UC), the integration of two or more real time communication systems into one platform, is a viable solution in tackling this pressure...
In this study we verified what kind of mobile information services passengers need on board through empirical research on commercial commuting trains. We provided rail information services as well as marketing tools such as news, shop information, advertisements and coupons for smartphones. A content server and Wi-Fi access points were newly installed on trains with the server connecting to an existing...
In this paper, we propose extended code architecture to express more information in existing iBeacon. Information that is available to the user is limited to 4byte because user can only use Major and Minor of iBeacon. Proposed scheme can use more information by transmitting consecutively Beacon signal containing classification and detailed information. When it comes to using more information of iBeacon,...
Software as a Service is a method of licensing and delivering software on-demand based on a centralized hosting solution which absolves the client of the hardware costs that come with high-end client-server server hosted solutions, the maintenance and hot-spare availability of that hardware and the continuous renewal costs. While small-medium businesses (SMBs) fit well in the client perspective of...
This paper links the economic cost of the cloud infrastructure to the business model of an internet-based company in order to evaluate costs and benefits of web applications. To this end, performance models and indexes related to the usage of the main system resources (i.e. processor, memory, storage and network bandwidth) have been reformulated to include new useful metrics for business management,...
Cloud computing has emerged as one of the enabling technologies that allows the business and IT world to use computer resource effectively and more efficiently. Microsoft Azure provides a Windows based environment for running applications and storing data on servers in data centers; SQL Azure provides data services in the cloud based on SQL Server; and .NET Services offer distributed infrastructure...
Cloud service providers offer their customers to rent or release hardware resources (CPU, RAM, HDD), which are isolated in virtual machine instances, on demand. Increased load on customer applications or web services require more resources than a physical server can supply, which enforces the cloud provider to implement some load balancing technique in order to scatter the load among several virtual...
The presented OptInv software system provides support for inventory and sales optimization. Generally, small and medium enterprises cannot afford expensive Enterprise Resource Planning (ERP) systems, with effective supply management modules. Supplies are often managed based only on former experience. Inconvenient situations can occur when an order cannot be accomplished because the needed product...
The Internet of things is a new type of network, based on the traditional telecommunication network and the Internet. All the ordinary physical objects in the Internet of things can be addressing, independent and able to access to the network. Internet data center in the whole Internet system plays a central role, is responsible for the control and management of possessions networking physical nodes,...
