Please Explain

Discovery is a horizontal discovery. You point it at a range of IP addresses, for example, and say "Go discovery everything you can about the devices in that range!" It comes back with software, servers, database instances, printers, etc. and their relationships to each other. It is a very 'broad' way to discover your CIs and their relationships. If a CI such as a web server happens to be talking to a database that is not in that IP range, the connection won't be defined.

Service Mapping is a "vertical" or "top down" approach where you give it a starting point and it asks two questions. "What is this?" and "Who do you talk to?" It does this to build a business service out of the CIs and connections specific to that service. If there's a printer on the same floor, but not part of the business service (e.g. it's not in a configuration file we care about), it's not discovered. It's very 'surgical' in it's approach.

I hope that helps.
