With new requirements imposed by SOA-based business models, adaptive security enforcement on the application level becomes even more important. Our work on the enforcement framework to date has resulted in a comprehensive middleware-based solution leveraging on Web services technologies. However, potential merits of hardware-based solutions to further secure application exposure have not been considered so far. This paper describes a method for combining software resource level security features offered by Web services technologies, with the hardware-based security mechanisms offered by trusted computing platform and system virtualisation approaches. In particular, we propose trust-based architecture for protecting the enforcement middleware deployed at the policy enforcement endpoints of Web and grid services. The main motivation is to additionally secure execution environment of the applications, by providing virtual machine level separation that maps from logical domains imposed by Web services level enforcement policies.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124629051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper extends previous work on QoS brokering for SOAs by designing, implementing, and experimentally evaluating a service selection QoS broker that maximizes a utility function for service consumers. Utility functions allow stakeholders to ascribe a value to the usefulness of a system as a function of several attributes such as response time, throughput, and availability. This work assumes that consumers of services provide to a QoS broker their utility functions and their cost constraints on the requested services. Service providers register with the broker by providing service demands for each of the resources used by the services provided and cost functions for each of the services. Consumers request services from the QoS broker, which selects a service provider that maximizes the consumer's utility function subject to its cost constraint. The QoS broker uses analytic queuing models to predict the QoS values of the various services that could be selected under varying workload conditions. The broker and services were implemented using a J2EE/Weblogic platform and experiments were conducted to evaluate the broker's efficacy. Results showed that the broker adequately adapts its selection of service providers according to cost constraints.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128238534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we address the issue where a high-level change (e.g. change in business policy or rolling out of a new service) necessitates external events (generated from other enterprise system) to be handled by running workflow (WF) instances in the WFMS. Current solutions either require a change in the workflow process definition or change in the workflow engine - both being cost intensive solutions from an enterprise 's point of view since they compromise on enterprise backend downtime. HEMM circumvents this by introducing an overlay on top of existing WFMS and abstracting out unforeseen event handling from workflows. At the same time, it employs event transformation to map events to appropriate event handlers of running workflow instances, enabling them to adapt to new events that their process definitions do not handle. We demonstrate our prototype implementation with the example of rolling out a bundled service that is prevalent in telecom industry.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131853437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces some basic features of Web X.o that expands the current Web to the \"highest and brightest\" point. The key concept of Services HyperChain in the Web eXpandoo framework is introduced to provide an enabling technology architecture that supports the future Web, which coordinates multimedia presentations, human interactions, business processes, computing resources, and business applications in a uniform fashion. Today's Web 2.0 technologies are mainly dealing with the presentation and community-based interaction aspects in the Web X.o framework. The boundary among Web, desktop applications, and backend resources are removed by creating Services HyperChain in the Web eXpandoo framework. The IEEE Body of Knowledge on Services Computing system is used as a prototype to illustrate how the Service-Oriented Architecture (SOA) and Web 2.0 technologies are used to to realize the Services HyperChain with unified services resource and services ecosystem enablement architecture of Web X.o.","PeriodicalId":208234,"journal":{"name":"IEEE International Conference on Web Services (ICWS 2007)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114185326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
