IT asset management - Technology
CMDB
(Configuration Management Database)
A database of important technology components and the relationships between them
What's it for?
Keeps a shared record of important technology items and how they depend on one another.
For example…
Before patching a host, the engineer checks the CMDB to see which business services sit on it
During an outage, support checks the CMDB and sees that the failed server supports both payroll and the HR portal, so both services are treated as affected.
Think of it like…
City’s utility map: pipes, substations and buildings linked so diggers know what they might hit
