Patent attributes
A technology is disclosed for automated risk analysis for the deployment of software component updates in complex microservice architectures. Dependencies and versions of deployment situations in test setup environments and in a target environment are analyzed and compared to identify a version delta between tested and production deployments. Further, test results for test deployments are used to identify and remove unsuccessful test setups. Successful test setups are ranked according to extend of their version delta against the target environment and one of the successful test setups is selected according to a deployment strategy. After a test setup is selected, a deployment plan considering service versions and dependencies is generated that guarantees a tested and functional state of the target environment after each deployment step.
