Adaptable Decentralized Service Oriented Architecture

摘要: In the Service Oriented Architecture (SOA), BPEL specified business processes are executed by non-scalable centralized orchestration engines. order to address scalability issue, decentralized engines applied, which decentralize into static fragments at design time without considering runtime requirements. The then encapsulated components such as agents. There a variety of attitudes towards workflow decentralization; however, only few them produce adaptable with environment. this paper, producing is presented in two aspects. first one frequent-path adaptability that equal finding closely interrelated activities and encapsulating same fragment omit communication cost activities. Another aspect proportional-fragment adaptability, analogous proportionality produced number engine machines. It extenuates internal among on machine. An ever-changing environment along mentioned aspects may result process versions runtime. Thus, an Adaptable Decentralized Workflow Execution Framework (ADWEF) introduced proposes abstraction decentralization SOA layer. Furthermore, ADWEF architectures Type-1 Type-2 support execution created methods, customized known Hierarchical Process Decentralization (HPD) Intelligent (HIPD). However, mapping current system conditions suitable method considered future work. Evaluations methods substantiate both demonstrate range improvements response-time, throughput, bandwidth-usage compared previous methods.
