| Summary: | In order to solve the problem of the lack of heterogeneity and dynamics of cloud application services with a single executor, and the difficulty of dealing with the security threats of unknown vulnerabilities and backdoors, a mimic cloud service architecture was proposed. In this architecture, the application services provided by the cloud platform were constructed into a service package based on mimic defense technology, so that the application services had the endogenous security features and robustness brought by mimic structure. At the same time, two key mimic cloud services operating mechanism，policy scheduling and adjudication mechanism were discussed. The experimental results and analysis show that the mimic cloud service obtains better security and its response time delay can be reduced by reducing the performance difference of the executor.
