Multi-layer deployment password service system and method in cloud environment

The invention discloses a multi-layer deployment password service system and method in a cloud environment, and belongs to the technical field of password service application. The system comprises a first-level password service subsystem used for executing a first-level password service based on a main target strategy, issuing a secondary target strategy to a second-level password service subsystem, obtaining first-level password service data generated after the first-level password service is executed, and sending the first-level password service data to a second-level password service subsystem; the second-level password service subsystem receives second-level password service data uploaded by the second-level password service subsystem, and stores the first-level password service data and the second-level password service data; and the second-level password service subsystem is used for receiving the secondary target strategy issued by the first-level password service subsystem, executing a second-level pa
