In this paper, a forensic framework has been developed to do cloud forensics in OpenStack for infrastructure as a service model using the existing forensic tools. For the instances which have been allotted to the user, the snapshots of volatile random access memory and image from the hard disk (cinder) in the specific path where it is mounted on should be acquired to do forensics. Adding to internal,...
Modern Business Process Management (BPM) expands to cover the partner organizations' business processes across organizational boundaries supports organizations' to coordinate the flow of information among organizations' and link their business processes. Over the years enterprises have constructed extensive networks of bridges to other organizations in order to deliver their corporate business services...
In a dynamic and heterogeneous world as the Web, the need often arises to update XML data, as well as their structures, to adhere to new domain requirements. Updates may break compliance of data to schemas, and updates at schema level may in addition require to adapt associated documents to the new schema. Moreover, emerging application contexts in which updates come from different sources, such as...
Over the Internet, e-Learning has speeded up the knowledge transfer without restrictions on time and space in recent years. In order to achieve the goal of knowledge sharing and reusing interactively, lots of available e-Learning standards have been adapted to complete this purpose. Normally, learning objects meeting these standards are sharable with other e-Learning platforms. Most e-Learning platforms,...
Cloud computing provides a new paradigm for easy access to larger scale computing resources over the Internet, thus offering an alternative solution to huge data processing and heavy computational work in power system. In this paper, InterPSS Cloud Edition, a cloud computing based platform for power system analysis, is set up by InterPSS development team using Google App Engine (GAE). At the current...
As the infrastructure for the healthcare system, The District Medical Data Center need to be built at first. The model of architecture of District Medical Data Center is proposed in the paper. Both the advantages and disadvantages of the model are set forth while the view is presented. The District Medical Data Center is “patient-centered” instead of “accounting-centered” in the ordinary hospital...
The paper has deeply analyzed and researched JavaScript application in the browser. It has brought forward future computer application and developmental new ideas based on Web-Kit features and cloud computing concept. In web2.0 framework it has technically implemented application model in JavaScript virtual machine. Thus it breaks the current browser can not effectively use shared resources in the...
The programmable network envisioned in the late 1990s within standardization and research for the Intelligent Network is taking another attempt to come into reality using IP-based Next Generation Networks (NGN) and Application Programming Interfaces (API) for open developer access. Adopting technical concepts of providing high-level APIs for open service access from the Internet and World Wide Web...
In recent days more and more software developments tools become distributed by the SaaS (Software-As-A Service) model alongside with ready-to-install products. The developers of task and bug tracking systems now offer their solutions by a monthly fee. For instance, JIRA Studio produced by Atlassian can be connected to a corporative domain by subscription. This scheme allows software companies to reduce...
Cloud computing as an emerging computing mode can be applied to the District Medical Data Center. This is a new proposal raised in the paper. The rudiment of District Medical Data Center based on cloud computing is established. A comparison is made between the samples from the rudiment and the samples from the general systems. XML is suitable to both express the multi-element unstructured data and...
Cyberworlds in the era of 'cloud' computing are being created on the Web where data and its dependencies are constantly changing and evolving. The problem of combinatorial explosion in system development inevitably arises when dealing with cyberworlds. To solve the problem, we have developed a data processing system called the Cellular Data System (CDS), based on the Incrementally Modular Abstraction...
The steady drumbeat of Cloud as a disruptive influence for Infrastructure Service Providers (ISP's) and the enablement vehicle for Software As A Service (SAAS)providers can be heard loud and clear in the industry today. In fact, Cloud is probably at the peak of the hype curve, and already there are identified challenges associated with effective deployment for business critical applications (so called...
Information visualisation techniques have sometimes been slow to diffuse into more widespread public use. Recent advances in cloud computing have opened up opportunities to bring information visualisation to the masses in ways previously not possible. Liquid diagrams are a suite of information visualisation gadgets written in Flex, which visualise live data contained in Google Docs spreadsheets through...
Cloud Computing is a paradigm in which data, applications or software are accessed over a network. This network of servers is called as “Cloud”. Using a client such as desktops, entertainment centers, tablet computers, notebooks, wall computers, handhelds etc, users can reach into the cloud for resources as they need them. Cloud computing is on-demand access to virtualized IT resources that are housed...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
Availability of enormous processing power and immense storage capacity drive Cloud computing. Information industry oracles like Google and Microsoft are delivering their next generation of products through Cloud. With the success of Amazon Cloud computing service everyone is laying on line to adopt it. Increased processing capabilities of enterprise servers do not mean that hosted services can handle...
Although event recording on a computer system (also known as logging) is of utmost importance for reconstructing and detecting security relevant events, currently no adequate and sophisticated solution for complex environments, such as Grid and Cloud Computing, exist. Current LOG file formats lack of several important factors, hindering automatic evaluation needed for distributed systems to comply...
Cloud provides dynamically computing services for large scales of data over the Internet. IaaS(information as a service) is one of utilities to provide information service in Cloud computing. Large scales of XML data are produced continually in Internet. Efficient information filtering services are needed. Previous XML filter approaches aim at XPath queries. However, many users tend to use keywords...
Containing runaway IT costs is one of the top priorities for enterprises. Cloud Computing, with its on-demand provisioning capability on shared resources, has emerged as a new paradigm for managing IT costs. In this paper, we describe a framework to simplify deployment of complex solutions on a Cloud infrastructure. We discuss the concept of a composite appliance and show how it can be used to reduce...
The transition to cloud computing and SaaS is a disruptive trend where users can conveniently access the services through browsers at any clients. In addition, with the prevalence of Web 2.0 and AJAX techniques, a browser-based client can have complex application logic and fancy user interface that are comparable to traditional desktop applications. This paper reports the study of workload construction...
