A heterogeneous micro-service security enhancement deployment method based on simulated annealing

Abstract

This invention discloses a method for enhancing the security of heterogeneous microservices based on simulated annealing. The method is as follows: S1, Variant Selection: Ignoring nodes, variants are selected only if the constraints are met; S2, Node Deployment: A greedy algorithm is used to deploy the selected variants to nodes one by one according to the runtime dependency chain, maximizing the security of the deployed system while satisfying the constraints. This invention can adapt to different needs by adjusting the parameters of the simulated annealing algorithm. When the system complexity is low, the initial temperature and maximum number of iterations can be appropriately reduced to obtain a faster solution speed; when the system is more complex, a larger initial temperature and number of iterations are used to obtain a better solution. This invention is applicable to situations where there are multiple functionally equivalent variants of the same microservice. By modeling nodes, microservices, and microservice dependencies, and combining the deployment method of this invention, a deployment scheme is generated.
