Based on redundancy and diversity

the method of enhancing system survivability was proposed by dynami-cally configuring atomic modules.According to the history average response time

survivability curves were drawn.The autonomous configuration algorithm was designed based on the survivability of atomic modules

system efficiency and quality of service.The contrast experiment validated the algorithm’s correctness and validity in the condition of atomic modules have different failure rate.The simulation confirmed that this algorithm can enhance the service survivability when atomic module under attack or be ageing
