A Configuration Management Database (CMDB) is a centralized repository that stores information about Configuration Items (CIs), including their attributes and relationships. It's a key component of IT service management (ITSM), providing visibility into the components that make up IT services, like hardware, software, and documentation
It can be incredibly useful. One example is to have every every process linked to the VM it is running on and the host the VM is running on and the TCP port the process is listening on. If you have all the correct relationships defined then you can write a query like this to find every process on every VM listening on port 80 on a given VM host.
MATCH p = (host:VMHOST {name: 'your_host_name'})-[:RUNS]->(vm)-[:HAS_SERVICE]->(service)-[:EXPOSES_PORT]->(port:TCPPORT {port: 80})
RETURN p
This can save a absurd amount of time for analyzing the impacts of failures and security isolation compliance.
