Thebookconsistsofanintroductionandfivechaptersaddressingthefollowing topics: • Specification and Deployment of Business SOA Applications within a Configurable Framework Provided as a Service. This chapter introduces the main components and features of an integrated framework supporting business processes in a distributed ICT environment based on the Service-Oriented Architecture (SOA) paradigm. The framework’s features are divided into areas that span the whole life cycle of business-oriented ICT applications. The fra- mework provides applications and tools for business requirement analysis and comparison,selectionandcompositionofservices,efficientcommunicationand provisioning of computational resources, allocation of distributed, virtualized environments,aswellasmonitoringandmanagementofresourceutilizationand quality of service indicators. • Platform for Development of Electronic Markets of Sophisticated Business Services. A general architecture of a platform which enables development of electronic markets of sophisticated business services is proposed. The platform consistsofthefollowingelements:(i)ServiceBroker,(ii)ServiceRegistry,(iii) Quote Agents, (iv) Interface Repository, (v) Service servers, (vi) Planner and Task Manager, (vii) User interface, and (vii) Transaction Coordinator. • Applying the Service-Oriented Architecture at the Inter-Organizational LevelandforAutomationofAdministrativeProcedures.Thischapterintro- duces a multilevel SOA architecture, describing its core principles, technical layers,andindividuallevels(knownastheTeamLevelandtheInterorganizational v vi Preface Level).Anapproachtoautomationofadministrativeproceduresisalsopresented alongwithrelevantmodels.Thetraditionalapproachtomodelingandexecutionof administrative procedures is contrasted with dynamic composition. The applic- ability of the proposed concepts is studied in the context of a real-world SOA applicationfromtheconstructiondomain. • Dependability Infrastructure for SOA Applications. The basic services whichcompriseadependabilityinfrastructurearepresented(thisincludesgroup communication, replication, and recovery). Management aspects of SOA dependability infrastructures, including self-configuration and knowledge repository, are investigated. Security problems are also addressed and support forsecuritypolicydeploymentintheformoftheORCAframeworkisproposed. The applicability of all these concepts is analyzed in the context of the Healthcare Integration Platform and the Medical Event and Data Registration Platform. • Implementation, Deployment, and Governance of Adaptive SOA Systems. The goal of this chapter is to propose a pragmatic methodology for adding and managingadaptabilityinmultiplelayersoftheS3stack,andtopresenttheAS3 Studiopackage,whichisacompletesuiteoftoolssupportingextensionsofSOA systems with adaptability features. The adaptability aspects presented in this chapterareplacedinabroadercontextinordertoaddressawiderangeofSOA applications composed of software services (also known as Virtual Services) and hardware components (called Real-World Services).

InChap.1theconceptofdevelopmentandmanagementofSOA-basedapplica- tionswithinaconfigurableserviceplatformispresented.Allcomponentsofthemod- ularandreconfigurableplatformareimplementedasservices,enablingexploitation oftheSOAparadigmforconfigurationandmanagementpurposes.Theframeworkis dividedintofeatureswhichcovertheentirelifecycleofbusiness-orientedICT(Infor- mationandCommunicationTechnology)applicationdevelopment.Applicationsare responsibleforbusinessrequirementanalysisandcomparison,selectionandcompo- sitionofservices,efficientcommunicationandcomputationalresourceprovisioning aswellasallocationinadistributed,virtualizedenvironment.Topicssuchasopti- malresourceutilization,monitoringandmanagementarealsoaddressed.Theunique features of the platform include: business process compatibility, easy reconfigura- tionofcompositionschemes,visualsupportforrequirementsandservicedefinition, QoS (Quality of Service) assessment (including communication services) and ser- viceexecutioncontrol.Moreover,thischaptershowshowtodevelopeffectivetools forSOAmanagementandhowtheSOAparadigmmaybeappliedtoachievebetter interoperabilityandflexibility. The presented framework covers service request processing, from arrival of a request all the way to completion and evaluation of the requested task. The plat- form’s building blocks (modules) assure service request processing, composition of services (taking into account their functional and non-functional requirements), efficientprovisioningofcommunicationandcomputationalresources,executionof servicesinavirtualdistributedenvironmentandtheevaluationofthequalityofcom- posite services. All of the aforementioned modules can be applied as independent dataprocessingunitsorasaggregationsofsuchunits,supportingspecificareasof the requirements and service-matching processes for any given business scenario supportedbySOA-basedorlegacyinformationsystems.Allapplicationswithinthe platform are designed and implemented as open, modular, scalable, and heteroge- neouscomponents(services),integratedinaccordancewithSOAprinciples.Suchan approachallowsforintegrationofselectedapplicationstosupportvariousdecision- makingprocesses. The main contribution of this chapter is a novel approach to service selection, composition and execution. First, the basics of the business process description in 1 Introduction 3 thecontextofservicesareexplainedandanoriginalnotationisproposedtosupport service-oriented process description and SLA (Service Level Agreement) genera- tion.Subsequently,flexibleandadaptivecompositionandprovisioningofcomposite services within the original architecture is presented, allowing the use of various communication and computational services by domain-oriented services. A scal- able service execution environment, including an original service-based execution engine,isdiscussed.ServicevalidationwithinthelayeredmodelofSOAgovernance isaddressed,alongwithamethodforcompositeservicesecurityassessment.Finally, an approach to automatic generation of user interfaces for semantically-described compositeservicesisconsidered. Adifferentapproachtoautomationofsophisticatedbusinessprocessesispresented inChap.2.Itisbased ontheidea thatautomation can beperformediftheprocess of using a single business service is automated first. Four basic phases of using a businessserviceareidentifiedinthiscontext:(1)theclientsendsaquerytotheser- viceproviderandobtainsaquote;(2)anorderisplacedandacontractmade;(3)the serviceexecutesinaccordancewiththecontract;(4)paymentiseffected(thismay occasionallyprecedestep3).Thesephasesareinterrelated,sothatifthefirstphase (query-quote)canberealizedinanuniversalway,thenthewholeprocesscanbeauto- mated.Forthispurposearepresentationoftheserviceenvironment(XSDschemata ofdocumentsprocessedbyservices)isproposedasasemanticmodel(grounding) foradescriptionlanguagewhichcanbeappliedinthefirstphase,matchingservice performancewithclientrequirements. Theauthorsalsoproposeasetofextensionsforthebusinessservicearchitecture related to Web services and the Semantic Web. Within this architecture there are two methods of communication. The first method, used in the query-quote phase, consistsofexchangingmessagescontainingformulasinadescriptionlanguage.The secondmodeofcommunicationinvolvesdocumentprocessingusingWSDLandis appliedduringtheorder-contract,execution,andpaymentphases.Theconceptofa businessserviceandtheautomationofthequery-quotephaseenableautomationof thewholesophisticatedbusinessprocesses,involvingmanyservices. Theproposedtechnologyisspecifiedintheformofprotocols.Thecorrespond- ingprototype(acommunicationplatformfordevelopingelectronicmarkets,called SOA-enT) is generic and may be applied to any application domain if appropriate XSDschemata(relatedtotheproblemdomain)areintroducedintothesystem.

It should be noted that while electronic markets for consumer products are rel- atively well developed, the corresponding service markets are often restricted and focus on simple services provided on a mass scale. The main problem here is that offers and commissions are to be specified in a plain language, implying that the descriptionsofservicesrelatedtotheseoffersareimpreciseandnotformalenough
