Architecture-centric system is s self-adaptive goal's implementation platform, requirement is processed as business services, which is the driven power, agent internetware is built as granularity service's carrier, achieves autonomous barycenter model about architecture rules, completes its self-adaptive reasoning, in order to get services' discovery and design. About flexible real-time business sequence's logic, service agent's decision-making cluster is the learning adjustment mechanism, which can finish implementation topology's evolution of architecture-centric service.
