During application deployment, a number of configuration changes are made to the supporting systems. These changes could be new firewall rules, storage provisioning or virtual machines to run required services.
In an infrastructure items such as storage, firewall rulesets, networks etc. are often reffered to as ‘Objects’.

Not knowing what an object is for can add significant time to projects, especially migration tasks. Take a firewall migration, migrations often aim to reduce the number of rules. Usually this is done by cleaning up depreciated rulesets. However, too often the response to discovery questions is “I don’t know, better migrate that rule”.
