Overview of CMDB: why CMDB before we learn about what is CMDB it's important to know

Why CMDB is important in any organization to let's say there is an organization saas now. in order to manage and run IT Services sas now has a laptop for employees desktop for employees servers databases network routers and firewalls and all of these different devices are connected and placed in the network of the saas now an organization. and they are also in the working stage means they are up and running one day some employees of saas now started complaining about some network issues after some investigation it team found that one router was not working in the network however no one had enough information about the router as saas now manages the list of their devices. in an excel sheet that has very limited information, it technician tried to find more information about the router. they found that the router issue could be fixed only by a vendor who actually supports it they call the technician of the vendor and then technicians started working on the issue in the meantime of the issue no one had clear visibility including leadership and people had questions about which devices got issues who supports the device and what applications were impacted, later on, the vendor technician resolved the issue and it technicians of that organization inform the employees and leaders about the resolution of the issue however later itil leadership still had questions like do we know how many other devices were connected with that router and got impacted how many times the same router had issues in last six months however IT team did not know the answer as information about these devices and connected application to the same device the same router was very limited in this whole example issue was definitely resolved however it will not be called as effective and timely resolution of the incident

moreover, there was no possibility of tracking the impacts that occurred during the incident now let's say the sass now company has a database where we can store all the information of these devices rather than in excel sheet devices like laptops computers desktops routers databases firewalls all these different devices now this database can be referred anytime to get the information about any device of the organization whose information is stored and it can also, help to find the connected applications and other devices and this the database is called as CMDB configuration management database then what is CMDB it's really important to know what systems are being used in IT environment and what configurations we have in those systems to manage and improve IT service delivery in any organization
