Performance Optimization for Composite Services in Multiple Networks Environment
暂无分享,去创建一个
With the prevalence of web services, services orchestration evolves from intra-enterprise integration to cross-domain integration and involves multiple networks. In traditional centralized SOA, the execution engine suffers from single point of failure and performance of composite services will be affected by the network conditions because of cross domain message transmissions. In this paper, we present a decentralized orchestration model for cross-domain multiple networks environment. Based on this model, we propose a Genetic Algorithm to find an optimization deployment solution for component services with minimum cross-domain network cost and thus increase the performance of composite services.
