What is a Configuration Management Database?
A configuration management database (CMDB) is a central IT database that records and documents all of a company's IT resources (configuration items, CIs) and manages their relationships with one another. It enables transparency and control over the entire IT infrastructure and supports IT service management (ITSM) processes as well as IT operations management (ITOM), i.e. the entire IT administration management in the company.
The Configuration Management Database (CMDB) is that central information system for a company's IT infrastructure. It serves as Database for all IT resourcesincluding:
-
Hardware (e.g. servers, routers, workstations).
-
Software (e.g. operating systems, applications, licenses).
-
Network components (e.g. switches, firewalls, IP addresses).
-
Virtual and cloud resources (e.g. containers, VMs).
The CMDB not only records these Configuration Items (CIs)but also their Relationships and dependencies. This is crucial for an efficient IT Asset Management (ITAM), Change management and Troubleshootingas it offers complete documentation of all IT components and their links.
Modern CMDBs are often part of IT service management platforms (ITSM) like ServiceNow and form a Central database for IT Operations Management (ITOM). This enables companies to Automated IT processes and realize their Manage IT landscape efficiently.
Definitions of the CMDB according to ITIL 4 and FitSM
The definition of a Configuration Management Database (CMDB) may vary depending on Framework vary. Two widely used approaches are ITIL 4 and FitSM:
ITIL 4 (Information Technology Infrastructure Library) is an internationally recognized framework for IT Service Management (ITSM). According to ITIL 4 is a CMDB: "A database in which configuration data records are stored during their life cycle. It also manages the relationships between the configuration data records."
FitSM (Federated IT Service Management) is a lightweight ITSM framework designed specifically for smaller IT organizations was developed. According to FitSM, a CMDB is a: "Storage location for data on configuration items (CIs)." FitSM also emphasizes that a CMDB not necessarily a single central database must be, but rather multiple data stores can be put together.
These definitions make it clear that a CMDB is not just a Database for the storage of IT assets, but a Central source of information for IT administration and IT service management represents.
