Despite attractive benefits a range of barriers is inhibiting take-up of Cloud Computing services which in most public sector organisations remains at less than 5% of the ICT footprint. The generic factor inhibiting wider deployment is that use of Cloud Computing services exposes organisations to heightened risks. While the inherent risks can be managed, in the near term significant investment in skills, processes, tools and technology is a prerequisite for doing so efficiently. For many organisations that use ICT services, the level of investment needed will often be prohibitive. This has created the opportunity for the emergence of trusted cloud brokerage services that can invest strategically to assist organisations with the use of Cloud Computing services and management of the associated risks, developing service portfolios that reduce upfront costs, so that use of Cloud Computing services becomes the best choice on a project by project basis. This paper considers the benefits of Cloud Computing, identifies the barriers to take up and how these can be overcome, and considers how cloud services brokerages can potentially develop new capabilities to accelerate take-up and benefits realisation.

Web services provide an instantiation of the loosely coupled Service Oriented Architecture (SOA) and facilitate the process of enterprise application integration. However, with the explosive growth of the number of Web services published over the Internet, identifying a high quality of composite services by taking into account both functional and non-functional requirements of end users has become a real challenge that needs to be addressed. We propose in this paper an approach that adresses this challenge by considering a two-phase composition process. The composition first proceeds to generate an abstract plan based on Web service types using Dynamic Description Logics (DDL). This abstract plan is then concretized into an executable plan by selecting the appropriate Web service instances based on non-functional requirements.

The service cloud model allows for the composition of services into an application that can respond to tenant requests. The composition of services, which may originate with different vendors, results in a service chain that supports end-to-end round trip messaging. Thus, the service cloud model must support provisioning services for the request without incurring a conflict of interest (COI) in their message exchange among vendors. Service vendors must disclose their COI classes for storage and analysis by the cloud because as services are provisioned to an application, additional conflict classes may be added, preventing the service from future compositions to avoid COI. In this paper, we present a strategy to centrally store and monitor COI classes for services in a service chain using principles of the Chinese Wall Model. We introduce a Security Monitoring Database (SMDB) that audits and monitors the COI classes as they exist or are assigned to hosted services, including the tenant services making requests. We describe an algorithm to prevent COI before provisioning services and dynamically detect it during run time due to concurrent service invocations using the SMDB information.

Hadoop is a popular open source implementation of MapReduce, that has a number of prominent users including Yahoo!, Facebook, and Twitter. Though several works have focused on deploying algorithms on Hadoop MapReduce, research efforts into applying formal methods to prove the correctness of hadoop systems are limited. In this paper we propose a holistic approach to verify the correctness of hadoop systems using model checking techniques. We model Hadoop's parallel architecture to constraint it to valid start up ordering and identify and prove the benefits of data locality, deadlock-freeness and non-termination among others.

The data explosion and the tremendous growth in the volume of data generated from various IT services places an enormous demand on harnessing and smartly analyzing the generated data and enterprise contents. According to recent studies, it is predicted that the volume of such data will become 26 fold in the next five years. While there might be some existing technologies to support this, industry is frantically exploring new models that lead to more efficient and higher performance solutions. With the aid of cloud computing and high performance analytics such as scalable-parallel machine learning, big data could be the fuel to a smarter cloud-powered IT world. Through our work, we provide a state-of-the-art review of high-performance advanced cloud analytics in the literature in attempt to find the ideal real-time platform for distributed analytic computations.

Cloud computing has commoditized compute, storage, and networking resources creating an on-demand utility. Despite the attractiveness of this new paradigm, its adoption has been stymied by cloud platform's lack of transparency, which leaves customers unsure if their sensitive data and computation can be entrusted to the cloud. While techniques like encryption can protect customers' data at rest, clouds still lack mechanisms for customers to verify that their computations are being executed as expected, a guarantee one could obtain if they were running the computation in their own data center. In this paper, we present the cloud verifier (CV), a flexible framework that cloud vendors can configure to provide cloud monitoring services for customers to validate that their computations are configured and being run as expected in Infrastructure as a Service (IaaS) clouds. The CV builds a chain of trust from the customer to their hosted virtual machine (VM) instances through the cloud platform, enabling it to check customer-specified requirements against a comprehensive view of both the VM's load-time and run-time properties. In addition, the CV enables cloud vendors to provide more responsive remediation techniques than traditional attestation mechanisms. We built a proof of concept CV for the OpenStack cloud platform whose evaluation demonstrates that a single CV enables over 20,000 simultaneous customers to verify numerous properties with little impact on cloud application performance. As a result, the CV gives cloud customers a low-overhead method for assuring that their instances are running according to their requirements.

End-users are confined by the social networking platforms that they invest effort in to set up their social contacts and relationships. The centralized, monopolized, and silo approach of today's social networking providers discourage interoperability across platforms. Enterprises struggle to find a common social networking approach to deal with the diversity of social networking platforms of choice of their users. Though each social networking platform provides their own APIs for externalizing users' social data, they are not designed to interoperate with other platforms. In this paper, we propose Social Ontology and Semantic Actions (SOSA) as a de-centralized, inter-operable social networking model and runtime services that enterprises can use as social networking middleware components for interoperability of social networking platforms of their users. SOSA provides platform agnostic construct for contacts; relationship axiom association with contacts, with inherent inferences to compute memberships given a relationship axiom. SOSA also enables binding with enterprise services as semantic actions of a given relationship axiom. Social relationship can also be used incontext with enterprise services and distributed web tasking.
最终用户受限于他们投入精力建立社交联系和关系的社交网络平台。当今社交网络提供商的集中式、垄断式和竖井式方法阻碍了跨平台的互操作性。企业努力寻找一种通用的社交网络方法来应对用户选择的社交网络平台的多样性。尽管每个社交网络平台都提供了自己的api来外部化用户的社交数据，但它们并不是为与其他平台进行互操作而设计的。在本文中，我们提出社会本体和语义动作(Social Ontology and Semantic Actions, SOSA)作为一种分散的、可互操作的社交网络模型和运行时服务，企业可以将其用作社交网络中间件组件，实现其用户的社交网络平台的互操作性。SOSA为联系人提供平台无关的构造;关系公理与联系人的关联，用给定关系公理的固有推理来计算成员关系。SOSA还支持将企业服务绑定为给定关系公理的语义操作。社会关系也可以在企业服务和分布式web任务的上下文中使用。

Despite the increasing use of the web to support human activities, most web interactions required to accomplish personal goals are performed manually by users. Even though users can easily transform a goal into multiple web interactions, the manual governance of these interactions diminishes the user experience. Personalized web-tasking seeks to improve the user experience by automating personal web tasks. This automation is driven by user needs, matters of concerns, and personal context. An important concern in personalized web-tasking is task simplification, the process of decomposing a personal web task into simpler tasks that can readily be composed into bigger tasks. This position paper characterizes a set of task simplification challenges intended as starting points for advancing the field of personalized web-tasking.
