The document describes the structure and functions of a CMDB system. The CMDB contains information about servers including basic info, traffic data, and application info. It manages the full lifecycle of servers from commissioning to deployment. The CMDB uses queues, workers, and an interface to integrate with monitoring, alerting, and deployment systems. It stores data in a database. In the future, the CMDB aims to provide more advanced capabilities like traffic analysis, auto-deployment, and elasticity management.
