What is the difference between Discovery and ACC?

Hi @BoHyun Jung, 

Discovery is agentless, that means you deploy MID Servers in your environment which scans your network IP ranges an gathers data via dedicated protocols, eg., WMI for Windows or SSH for Unix systems. So no need to install anything on the systems you want to discover. Almost all device types with IP address could be discovered. But you need to create credentials with the right privileges to access the device via this protocols. And Firewalls between MID and target needs to allow this communication.

ACC is a agent you install directly on the systems (Windows and Unix only Support) which crawls the data and sends it to your instance. So no special credentials are needed and only 443 ports needs to be opened.

The results in your CMDB are almost the same. 

ACC can be used for devices which are not all time online or where you don't want to open the corresponding ports and don't want to provide credentials with high privileges. Discovery  is scheduled, so you should use this for devices which are online in the scheduled timeframe.
