<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2322</link>
<description><![CDATA[With the increasing prevalence of large scale cloud computing environments, how to place requested applications into available computing servers regarding to energy consumption has become an essential research problem, but existing application placement approaches are still not effective for live applications with dynamic characters. In this paper, we proposed a novel approach named EnaCloud, which enables application live placement dynamically with consideration of energy efficiency in a cloud platform. In EnaCloud, we use a Virtual Machine to encapsulate the application, which supports applications scheduling and live migration to minimize the number of running machines, so as to save energy. Specially, the application placement is abstracted as a bin packing problem, and an energy-aware heuristic algorithm is proposed to get an appropriate solution. In addition, an over-provision approach is presented to deal with the varying resource demands of applications. Our approach has been successfully implemented as useful components and fundamental services in the iVIC platform. Finally, we evaluate our approach by comprehensive experiments based on virtual machine monitor Xen and the results show that it is feasible. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0002/CLOUD-0002.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2324</link>
<description><![CDATA[With the popular use of service-oriented technologies, Database as a Service (DaaS) as a new paradigm is becoming a more practical and useful model for those enterprises who can&amp;rsquo;t afford the expensive DBMS products. However access control management by the database service provider (DSP) in the DaaS context is challenging because the DSP may be untrusted for the delegated data contents. In this paper, we first present an approach to implement the flexible access control enforcement management by applying a DSP re-encryption mechanism. Our approach not only can implement the selective access control of the encrypted data by the DSP, but also can relieve the users from the complex key derivation procedure. The underlying idea of our approach is that the DSP uses different re-encryption keys for users of the system to implement flexible access control enforcement management under the DSP re-encryption mechanism. We demonstrate the usefulness and security property of our flexible access control enforcement management, finally we analyze and resolve the possible attacks and information disclosure.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2326</link>
<description><![CDATA[When deploying services in a cloud, a balance must be found between performance and capacity of the service, and the memory available on nodes. This is further complicated if the number of replicas of an application is limited, for instance by the available number of licenses. The analysis of interference between services must scale to large numbers of host nodes, applications, replicas of applications, and classes of users. This paper combines a multi-dimensional packing heuristic and network flow optimization to satisfy simultaneous constraints on throughputs, processor utilizations, memory availability and license availability, at a minimum cost and with a minimum of host processors.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2328</link>
<description><![CDATA[Modern data centers use virtual machine based implementation for numerous advantages like resource isolation, hardware utilization, security and easy management. Applications are generally hosted on different virtual machines on a same physical machine. Virtual machine monitor like Xen is a popular tool to manage virtual machines by scheduling them to use resources such as CPU, memory and network. Performance isolation is the desirable thing in virtual machine based infrastructure to meet Service Level Objectives. Many experiments in this area measure the performance of applications while running the applications in different domains, which gives an insight into the problem of isolation. In this paper we run different kind of benchmarks simultaneously in Xen environment to evaluate the isolation strategy provided by Xen. Results are presented and discussed for different combinations and a case of I/O intensive applications with low response latency has been presented. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0005/CLOUD-0005.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2329</link>
<description><![CDATA[Cloud computing offers the potential to make parallel discrete event simulation capabilities more widely accessible to users who are not experts in this technology and do not have ready access to high performance computing equipment. Services hosted within the &amp;ldquo;cloud&amp;rdquo; can potentially incur processing delays due to load sharing among other active services, and can cause optimistic simulation protocols to perform poorly. This paper proposes a mechanism termed the Time Warp Straggler Message Identification Protocol (TW-SMIP) to address optimistic synchronization and performance issues associated with executing parallel discrete event simulation in cloud computing environments. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0006/CLOUD-0006.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2330</link>
<description><![CDATA[Client requests often span over several web services and these services have to be invoked in some sequence based on business logic of a composite service. BPEL language is used for specification of web service composition and has become the industry standard. Unfortunately BPEL lacks sound formal semantics which leads to errors in service composition. It is therefore necessary to model and verify BPEL specification before execution. In this paper, we model certain BPEL activities using Coloured Petri-Nets (CPN). CPN is similar to Petri-Nets (PN) with an extra advantage that it has programmable elements. Our models are compact, yet feature-complete as compared to other models. Moreover, we propose an algorithm to identify structurally similar sub-parts of CPN model and replace them with a transition. The subpart replaced forms a separate CPN. This not only reduces the size of model but allows the sub-parts moved out to be verified independently. Further, we get a model of constant size when each subtask of an activity is same.<div></div><div></div>]]></description>

<description><![CDATA[This paper introduces a Tele-Management system as a part of SmartUM which is a Ubiquitous Cloud Middleware for ubiquitous city (u-city). The cloud computing platform allows users to control remote devices. The users get data from a various kinds of remote sensors and scene images about the place of sensors from remote video cameras and control remote devices seeing the scene images of the remote place. Our cloud computing platform has context-awareness and can intelligently control the remote devices according to the circumstance scenario. We used ontology for the contextaware intelligence processing. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0008/CLOUD-0008.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<item><title><![CDATA[An Efficient Resource Management System for On-line Virtual Cluster Provision]]></title>
<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2352</link>
<description><![CDATA[As a prevalent paradigm for flexible, scalable and on-demand provisions of computing services, Cloud Computing can be an alternative platform for scientific computing. In this paper, we propose an efficient resource management system for on-line virtual clusters provision, aiming to provide immediately-available virtual clusters for academic users. Particularly, we investigated two crucial problems: efficient VM image management and intelligent resource mapping, either of them has remarkable impact on the performance of the system. VM image management includes image preparation and local image management on physical resources. A resource mapping refers to a mapping from user&amp;rsquo;s resource constraints to specific physical resources. We explore how to simplify VM image management and reduce image preparation overhead by the multicast file transferring and image caching/reusing. Additionally, the Load-Aware Mapping, a novel resource mapping strategy, is proposed in order to further reduce deploying overhead and make efficient use of resources. The strategy takes account of both image cache and VM load distribution information. System evaluation is conducted through various real stress workloads, and results show that our approaches are effective comparing to other common solutions. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0009/CLOUD-0009.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<description><![CDATA[Hadoop is a Distributed Filesystem and MapReduce framework originally developed for search applications by Google and subsequently adopted by the Apache foundation as an open source system. We propose that this parallel computing framework is well suited for a variety of service oriented science applications and, in particular, for satellite data processing of remote sensing systems. We show that, by installing Hadoop on a cluster of IBM PowerPC blade clusters, we can efficiently process multiyear remote sensing data, expect to see speed performance improvements over conventional multi-processor methodologies, and have more memory efficient implementation allowing for finer grid resolutions. Moreover, these improvements can be met without significant changes in coding structure.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2357</link>
<description><![CDATA[Proposal of Cloud Computing is tightly coupled with low cost. Reduction of cost is considered as an important advantage of Cloud. However, there are no available tools proper for cost calculation and analysis in Cloud environment. This paper presents our efforts towards filling in the gap. We format suits of metrics and formulas for the calculation of Cloud Total Cost of Ownership (TCO) and Utilization Cost, considering the elastic feature of Cloud infrastructure and widely adopted virtualization technology in Cloud. This provides a foundation for evaluating economic efficiency of Cloud and provides indications for cost optimization of Cloud. We have developed our calculation and analysis approach into a web tool which is used in the internal Cloud environment and demonstrate initially its analysis capability on the cost distribution and utilization imbalance factor.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2359</link>
<description><![CDATA[Software as a Service (SaaS) is an important technology innovation as well as a business model innovation to bring new opportunities to Small and Medium Enterprises (SME). There are different SaaS provisioning methods, depending on the customer profile, the cost of the required resources, and the price that customers are willing to pay. The core technology of SaaS-ization focuses on multi-tenancy, which means supporting multiple customers over the SaaS platform at the same time. In this paper, we describe an end-to-end methodology, together with a toolkit that supports the fine granularity multi-tenancy mechanism. This means using one single application instance to support multiple tenants, an approach that could save the Cloud infrastructure resources required to support high volumes of customers. Further, the methodology could lower the entry level of SaaS operators, as well as the user subscription fees.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2360</link>
<description><![CDATA[Web-business platforms offer business capabilities as enterprise services hosted in a multi-tenant cloud environment. Often there is a need to create heavyweight variants of these enterprise services to support: inherent variability in the underlying business process, industryspecific requirements, globalization concerns and customer-specific requirements. These variability concerns affect both the service interface and the service provider implementation and hence are crosscutting in nature. In this paper, we use principles of aspect-oriented software development to modularize these variability concerns. We also provide an aspect specification scheme to specify these concerns. We propose an approach to create heavyweight service variants centered on a Service Kernel, which forms a common service core across tenants. Heavyweight service variants are created by weaving aspects into the service kernel. Our approach provides improved governance for the provider while offering maximum flexibility for the consumers. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0014/CLOUD-0014.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2361</link>
<description><![CDATA[Service Oriented Architecture (SOA) is one central technical foundation supporting the rapidly emerging Cloud Computing paradigm. To date, however, its application practice is not always successful. One major reason is the lack of a systematic engineering process and tool supported by reusable architectural artifacts. Toward this ultimate goal, this paper proposes a variation-oriented analysis method of performing architectural building blocks (ABB)-based SOA solution design for enabling cloud application design. We present the modeling of solution-level architectural artifacts and their relationships, whose formalization enables event-based variation notification and propagation analysis. We report a prototype tool and describe how we extend the Unified Modeling Language (UML) mechanism to implement the system and enable solution-level variation analysis and enforcement in business cloud as an example. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0015/CLOUD-0015.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2363</link>
<description><![CDATA[The Cloud Computing concept offers dynamically scalable resources provisioned as a service over the Internet. Economic benefits are the main driver for the Cloud, since it promises the reduction of capital expenditure (CapEx) and operational expenditure (OpEx). In order for this to become reality, however, there are still some challenges to be solved. Amongst these are security and trust issues, since the user&amp;rsquo;s data has to be released to the Cloud and thus leaves the protectionsphere of the data owner. Most of the discussions on this topics are mainly driven by arguments related to organisational means. This paper focusses on technical security issues arising from the usage of Cloud services and especially by the underlying technologies used to build these cross-domain Internet-connected collaborations. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0016/CLOUD-0016.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<description><![CDATA[Cloud based services, by their nature, are distributed and traditional operation and management processes that often exert centralized control are not suited for cloud services operation and management. This paper introduces a Policy-based Event-driven Service-oriented Architecture (PESA) that enables the manageability of these loosely coupled services distributed across multiple public or private clouds or a hybrid cloud. PESA allows the implementation of policy driven management of service availability, performance, security and risk management. Using the concept of logical and virtual partitioning of the business service fabric into sub-fabrics &amp;ndash; islands of services that may span company, geographical, and technological boundaries, public and private clouds, and corporate data centers, we describe a conceptual management architecture for policy enforcement. An example describes service availability and performance assurance in a business process implementation using a set of loosely coupled service components in a virtual cloud.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2366</link>
<description><![CDATA[Recently, REpresentational State Transfer (REST) has been proposed as an alternative architecture for Web services. In the era of Cloud and Web 2.0, many complex Web service-based systems such as e-Business and e-Government applications have adopted REST. Unfortunately, the REST approach has been applied to few cases in management systems, especially for a management system for cloud computing infrastructures. In this paper, we design and implement a RESTful Cloud Management System (CMS). Managed elements can be modelled as resources in REST and operations in existing systems can be evaluated using four methods of REST or a combination of them. We also show how components of existing management systems can be realized as REST-style Web services.<div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\CLOUD-0017.ppt.\"  target=_black></a><br></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2367</link>
<description><![CDATA[Most of the work on cloud scalability has focused on the granularity of applications and systems deployed on the cloud and on how to adjust their resource assignment according to the scale or volume of the requests. In this paper, we present a scheme for improving the scalability of servicebased applications in a cloud from the granularity of the constituent services and their individual placement in the cloud. The approach we take is to analyze the communication patterns among the service operations of service-based applications and to analyze the assignment of the involved services to the available servers. We define a notion of scalability for service-based applications in a cloud and a framework to measure the scalability. We then propose an optimized assignment strategy to improve the scalability of composite Web services in terms of the productivity of such services. We report preliminary simulation experimental results that show the effectiveness of our scheme. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0019/CLOUD-0019.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<description><![CDATA[The Cloud phenomenon is quickly growing towards becoming the de facto standard of Internet Computing, storage and hosting both in industry and academia. The large scalability possibilities offered by Cloud platforms can be harnessed not only for services and applications hosting but also as a raw on-demand computing resource. This paper proposes the use of a Cloud system as a raw computational on-demand resource for a Grid middleware. We illustrate a proof of concept by considering the DIET-Solve Grid middleware and the EUCALYPTUS open-source Cloud platform. <div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\CLOUD-II 2009-0021.ppt.\"  target=_black></a><br></div><div></div>]]></description>

<description><![CDATA[Software-as-a-Service (SaaS) helps organizations avoid capital expenditure and pay for the functionality as an operational expenditure. Though enterprises are unlikely to use SaaS model for all their information systems needs, certain business functionalities such as Sales Force Automation (SFA), are more seen to be implemented using SaaS model. Such demand has prompted quite a few vendors to offer SFA functionality as SaaS. Enterprises need to adopt an objective approach to ensure they select the most appropriate SaaS product for their needs. This paper presents an approach that makes use of Analytic Hierarchy Process (AHP) technique for prioritizing the product features and also for expert-led scoring of the products.<div></div><div></div>]]></description>

In this paper, based on a brief discussion of the service value concept, we present a service value life cycle model (SVLC), where the value delivery process is decomposed into 7 phases (bi-lateral searching, bi-lateral negotiation, unilateral preparation, co-production, transferring, usage, and payment). Each phase&amp;rsquo;s repeatable tasks, output, quality metrics of the process and output, and possible innovative design decisions, were elaborately analyzed. A C2C service system, Taobao.com, is briefly discussed to help understand SVLC in the real world. Comparisons between SVLC and traditional service research shows that SVLC provides some significance to systematical service innovations and service quality metrics design from life cycle (temporal) point of view. Potential effects on service computing research and some future work are also discussed. <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0023/CLOUD-0023.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2375</link>
<description><![CDATA[The IT industry traditionally offers system services to user companies. The services which integrate software and hardware products are geared toward product-based business models. However, with the emergence of cloud computing, users&amp;rsquo; in-house systems and applications are virtualized on the net, and are replaced with ones provided through outsourcing services. The alternative systems will be combinations of service functions of their companies&amp;rsquo; and of outsourcers&amp;rsquo;. This will relieve user companies from their legacy systems, allowing them to concentrate on their competence and to develop new business models effectively. In order to meet this trend, IT vendors should focus not only on the values of platform development but also on those of creating business opportunities. They need to share users&amp;rsquo; business goals and collaborate with them to enhance their business values. This paper proposes a framework and supporting tools to co-create business values between IT vendors and clients through the business lifecycle, showing the results from partly applying them to the early stages of development of e-learning services <div align="center"><a href="uploadfiles/2009/VIDEO/CLOUD-0024/CLOUD-0024.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2376</link>
<description><![CDATA[While IT management services represent a mature subject in the IT business arena, the emerging cloud generation of management services require critical enhancements to the current processes and technologies in order to deliver IT management remotely with rapid onboarding and minimal labor involvement from experts, to be affordable and scale up to the promise of the cloud. Traditional Remote Infrastructure Management (RIM) service providers use their own Network Operations Centers (NOC) to remotely monitor and manage customers&amp;rsquo; IT infrastructure. The primary business value for RIM services is that it helps global enterprises to small and medium businesses (SMB) to outsource the burden of managing their IT infrastructure. Although the IT management service itself delivered this way is more affordable, the RIM customer on-boarding process particularly is not, taking between one to two months of expensive labor. This paper describes what and how IT management processes, technologies and skills can be improved to provide remote customer on-boarding at an appropriate speed for delivery from the cloud. Our contributions consist of major enhancements in a key onboarding area, namely IT discovery. Experimental results show that our approach aligns the RIM on-boarding methods to the cloud expectations both from a time as well as quality perspective.<div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\CLOUD-0025.ppt.\"  target=_black></a><br></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2377</link>
<description><![CDATA[Service Level Agreements (SLAs) are used to manifest guarantees about certain functional and non-functional aspects of service execution. Service providers are confronted with a hard problem when trying to estimate reasonable QoS levels and other default settings for SLA templates. The insufficient use of formal service behaviour descriptions, varying resource demands and a choice of configuration options expected by users contribute to this issue. We present our solution of gathering monitoring data at runtime and feeding it back into the service registry to adjust descriptions and make contract template derivation a more realistic process. In addition, we show how to extend SOA building blocks such as service discoveries and SLA managers with the adjustment mechanism.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2379</link>
<description><![CDATA[Selecting high quality services from available ones plays an important role in services composition. Trust and reputation mechanisms offer a promising way to solve the services selection problem. Current researches on this topic focus on gathering, storing and aggregating feedbacks which can be execution data by monitoring services or consumer ratings. However, besides the feedback itself, the reliability of feedbacks should be considered equally crucial. In this paper, different from previous work, we draw our attention to find trusted feedback submitters who are more likely to give reliable feedbacks. We proposed a service evaluation framework where a &amp;ldquo;Web of Trust&amp;rdquo; is built and maintained. Moreover, we presented a Kalman Filter based algorithm to reveal the trusted feedback submitters. The presented work in this paper aims to supplement the service evaluation and ultimately facilitate the services selection process. We validated our approach by both simulated and real-world evaluations.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2381</link>
<description><![CDATA[In this paper, we analyze the performance of an end-toend Mortgage Origination (MO) process. The process begins with the submission of a mortgage application by an applicant to a lender and ends with one of the following outcomes: closing, i.e., loan approved by the lender and accepted by the applicant or non-closing, i.e., loan either rejected by the lender, or approved by the lender and not accepted by the applicant. Ranking mortgage applications by their predicted likelihood of closing at various steps in the process is useful for process efficiency and identification of actionable insights to convert applications likely to non-close into those that are likely to close.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2382</link>
<description><![CDATA[Modern distributed systems require collaborations between individual organizations. The collaborations consist of complex relationships and interactions among distinct administrative domains. Different forms of collaboration can be implemented. As a result, different security control requirements emerge. For example, service propagation requires all collaborating partners to have compatible authorization policies. On the other hand, integratable policies are required for organizations who intend to engage in service composition. Therefore, a thorough understanding ofdifferent collaboration patterns is a prerequisite for secure inter-organizational collaboration. In this paper, we define basic inter-organizational collaboration patterns and propose Collaboration Policies that outline requirements for collaboration partners in each collaboration pattern in terms of authorization policy consistency.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2384</link>
<description><![CDATA[The ever increasing amount of content on the Internet has fostered many efforts seeking to leverage this potentially yottascale information source. Service systems using advanced data and text analytics techniques have been developed to perform knowledge gathering and information discovery over Web data. Information gathered from free and public sources on the Web is frequently integrated with enterprise and proprietary data to create sophisticated service systems able to provide insight in an increasing number of business critical areas. Unfortunately, for fixed and or limited resource projects, consistent and reliable ingestion and integration of content often dominates the effort, reducing the time available for developing core analytics and presentations that differentiate and define an information service. If this initial data extraction, translation and loading of information (known as ETL in the database world) can be abstracted for these web sources, it would provide an important core technology on which Web-based information services could be more rapidly and inexpensively developed and deployed. This paper presents such a system &amp;ndash; MONGOOSE &amp;ndash; an approach that seeks to reduce the time spent creating a reliable data ingest and integration system and thus reducing the time-to-impact of advanced analytics service solutions.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2385</link>
<description><![CDATA[Problem management is a critical and expensive element for delivering IT service management and touches various levels of managed IT infrastructure. While problem management has been mostly reactive, recent work is studying how to leverage large problem ticket information from similar IT infrastructures to probatively predict the onset of problems. Because of the sheer size and complexity of problem tickets, supervised learning algorithms have been the method of choice for problem ticket classification, relying on labeled (or pre-classified) tickets from one managed infrastructure to automatically create signatures for similar infrastructures. However, where there are insufficient preclassified data, leveraging human expertise to develop classification rules can be more efficient. In this paper, we describe a rule-based crowdsourcing approach, where experts can author classification rules and a social networking based platform (called xPad) is used to socialize and execute these rules by large practitioner communities. Using real data sets from several large IT delivery centers, we demonstrate that this approach balances between two key criteria: accuracy and cost effectiveness.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2415</link>
<description><![CDATA[The Cloud phenomenon is quickly growing towards becoming the de facto standard of Internet Computing, storage and hosting both in industry and academia. The large scalability possibilities offered by Cloud platforms can be harnessed not only for services and applications hosting but also as a raw on-demand computing resource. This paper proposes the use of a Cloud system as a raw computational on-demand resource for a Grid middleware. We illustrate a proof of concept by considering the DIET-Solve Grid middleware and the EUCALYPTUS open-source Cloud platform.<div></div><div></div>]]></description>
