Exploring the reach of ServiceNow CMDB capabilities
Essentially, the CMDB really is the engine of the ServiceNow platform, right? The CMDB contains all of that data about an IT environment. And it's not just hardware and software. It's a definition of business services, right? It's basically made of what's called configuration items. These configuration items can be physical, they can be logical, and conceptual. In addition to that, the CMDB also contains information about other aspects of your environment, such as your organizational structure, right? Which is— can come under an entity kind of a structure, which is part of the CMDB. In addition to that, it has business services. It has financial information. All of that, if you think about what a very rich, robust, amateur CMDB holds, it's more than a list of stuff you own or have. It is really a broken down—when I say “broken down,” it's a really highly logical, highly disciplined set of data about your organization that, through multiple lenses—including security— you can manage your organization through that set of data in the CMDB.
