The host profiles feature creates a profile that encapsulates the host configuration and helps to manage the host configuration, especially in environments where an administrator manages more than one host or cluster in vCenter Server.

Host profiles eliminates per-host, manual, or UI-based host configuration and maintains configuration consistency and correctness across the datacenter by using host profile policies. These policies capture the blueprint of a known, validated reference host configuration and use this to configure networking, storage, security, and other settings on multiple hosts or clusters. You can then check a host or cluster against a profile’s configuration for any deviations.
