  • 22 Nov 2017 - A CMDB for IT infrastructures: Can we use a CMDB for the whole IT management? In this post we'll see what a CMDB should be, and we'll see how to import existing network devices into a CMDB using NAPALM. Finally we'll see how to operate on network devices from a CMDB and how pushing configurations. This is a compendium to my speech in Milano for AutomateIT² event.
