SaaS (Software as a Service) has been widely recognized as a new kind of service. Meanwhile, PaaS (Platform as a Service) is emerging in recent years. The management of service on PaaS platform is quite different from that of traditional services. This paper analyzed the service management activities of PaaS and proposed an intuitive and easy approach to the service management activities such as deploying, monitoring and controlling. All these can be taken by the service developers themselves. Based on the proposed approach, a flexible and scalable self-management framework is implemented. The key characteristics of the framework are the using of static analysis technique and runtime monitoring technique. The framework is used in a real PaaS—“SASEP” (Service Aided Software Engineering Platform). SASEP collects plenty of services, which are all closely related with software development and maintenance.

Standardized business documents are a prerequisite for successful information exchange in electronic business transactions. The United Nations Centre for Trade Facilitation and eBusiness (UN/CEFACT) provides a conceptual modeling approach, called Core Components, used by Business Partners (BPs) for defining business document models (BDMs). These BDMs are essential for defining service interfaces in service-oriented systems. However, in such a highly dynamic environment with ever-changing market demands, BPs are confronted with the need to revise their BDMs resulting in new versions of BDMs. Furthermore, BPs may dictate the use of new versions of BDMs. However, small- and medium-sized enterprises (SMEs) may not always adopt new BDM versions due to the cost and effort involved, inhibiting electronic information exchange. In this paper, we present a framework for dealing with interoperability issues in service-oriented systems through providing BPs with Business Document Interoperability as a Service. Having such a framework at hand provides SMEs with a low-cost and light-weight approach for dealing with evolving market requirements and hence evolving business documents. Furthermore, we present a prototypical implementation as well as an evaluation of the framework proposed.

Scientific workflows normally consist of multiple applications acquiring and transforming data, running data intensive analyses and visualizing the results for scientific discovery. In this paper, we present our application of Service-Oriented Architecture (SOA) to compose and deploy systems biology workflows. In developing this application, our solution uses MeDICi a middleware framework built on SOA platforms as an integration layer. We discuss our experience and lessons learnt about this solution that are generally applicable to scientific workflows in other domains.

Third party services can change without notification as they are usually under the control of external providers. Unexpected changes can clash the integrity of a composition and monitoring approaches have been proposed to detect such changes. Many of these approaches are based on executing all test cases of a regression test set to check whether the behavior of the monitored service remains the same. Such strategy, however, can be very expensive as costs may be associated to the testing activity. In this paper we propose using structural testing information to detect structural changes of monitored services and select only a reduced number of test cases of the regression test set to be executed. We also present three exploratory case studies to evaluate our approach.

Cloud platform provides an infrastructure for resource sharing, software hosting and service delivering in a pay-per-use approach. To test the cloud-based software systems, techniques and tools are necessary to address unique quality concerns of the cloud infrastructure such as massive scalability and dynamic configuration. The tools can also be built on the cloud platform to benefit from virtualized platform and services, massive resources, and parallelized execution. The paper makes a survey of representative approaches and typical tools for cloud testing. It identifies the needs for cloud testing tools including multi-layer testing, SLA-based testing, large scale simulation, and on-demand test environment. To address the needs, it investigates the new architecture and techniques for designing testing tools for the cloud and in the cloud. Tool implementations are surveyed considering different approaches including migrated conventional tools, research tools, commercial tools and facilities like benchmark and testbed. Based on the analysis of state-of-the-art practices, the paper further investigates future trend of testing tool research and development from both capability and usability perspectives.

The two main aspects of the web service composition problem are control flow and data mismatches. Several approaches have been reported in the literature to tackle the former; while the latter, and equally relevant aspect for the correct compositional behavior, has either been ignored or addressed to a very limited extent. This paper describes a formal approach based on model checking, that guarantees the correct interaction of services in a composition by managing control flow and resolving data mismatches at semantic, syntactic and structural levels, in a unified manner. A tableau based algorithm is used to generate and explore compositions in a goal-directed fashion, that proves or disproves the existence of a service orchestrator. Successful synthesis of the orchestrator confirms that the required functionality is realizable. Data models to detect and resolve data mismatches are generated using WSDL documents and regular expressions. Experimental results provide strong testimony that the approach can be effectively applied in a practical setting.

The Service-Oriented Architecture (SOA) provided by the Web Services standards supports Model-Driven Development, it allows global business process models described in the Business Process Modeling Notation (BPMN) or as UML Activity Diagrams to be transformed into Web Services components specified by WSDL and/or BPEL. We have experimented the transformation of UML Activity Diagrams to several BPEL processes using the IBM Rational Software Architect (RSA) tool. These diagrams were derived from the specification of global system behavior where each activity may represent some collaboration between several system components in distributed systems. The derived component behaviors assure that the global behavior will be realized by coordinating the actions of the components through the exchange of asynchronous messages. In this paper, we describe how this method can be adapted to the context where the system components will be implemented as BPEL processes. We found out that the IBM Rational tool does not support some important asynchronous message exchange scenarios, and we describe here how the generated BPEL processes can be manually adapted. We also discuss some difficulties that arise in relation with input message buffering. since we assume that the received messages remain in a buffer pool until they are required by the destination process. This message buffering is largely provided by the BPEL execution environment. We explain in this paper how all these problems can be resolved by simple modifications of the automatically generated component behaviors in BPEL.

It is now well-accepted that formal methods are helpful for many problems raised in Web Service area. In this paper, we propose a new process algebra to formalize the environment-based specification of Web Services. From our point of view, the capability of a Web Service is considered in terms of the effects it imposes on the environment during its execution. The environment is composed of numbers of environment entities. For each entity, we first use the algebraic specification language CASL to describe its data(static) aspect, and then use our new process algebra to formally specify its dynamic behavior aspect. Based on that, a Web Service is specified as a process, and we can easily characterize its interaction with the environment. Furthermore, a behavior equivalence between two web services is established by using the notion of strong bisimulation in the new process algebra, some important properties of this relation are proved as well.

With the rapid growth of Web services, service discovery becomes an important and difficult issue. Traditional UDDI-based and WSDL-based methods of service discovery have low precision, and semantic-based service discovery methods are usually inefficient and time-consuming. We observe that social annotations can optimize both precision and efficiency of service discovery. In this paper, we propose a social-annotation-based service discovery method by using a learning to rank method, and propose two algorithms, Query Annotation Relevance (QAR) and Service Annotation Ranking (SAR), to calculate the dynamic Query-dependent feature and the static Query-independent feature respectively. Our experiments show that our method is effective for improving service discovery performance.

Service oriented computing (SOC) and cloud computing paradigm has emerged as an approach which enables ubiquitous, on-demand network accesses to a shared pool of flexibly reconfigurable computing resources. The increasing trends of electrical consumption within data centres are a growing concern for business owners as they are quickly becoming a large fraction of the total cost of ownership. There are several challenges and opportunities within a data centre to lower the electrical costs and improve the energy efficiency. Since servers and air conditioners represent the top users of electrical power in the data centre, this research sets out to explore methods from each subsystem of the data centre as part of an overall energy efficient solution. In this paper, we investigate the current trends of Green IT awareness and how the deployment of IT equipment and Site Infrastructure equipment optimization techniques which can offer a solution to a global issue by reducing carbon emissions.
