The Configuration Management Database (CMDB) in ServiceNow, often referred to as “Snow CMDB,” is a comprehensive database that stores information about hardware, software, networks, and other assets in an IT environment. It serves as a central repository where all configuration data is consolidated, managed, and maintained. CMDB in ServiceNow is crucial for IT service management as it provides detailed insights into the infrastructure, enabling better decision-making, risk management, and support for ITIL processes like incident, problem, and change management. The CMDB is integral to maintaining an organized, efficient, and effective IT infrastructure.
