To add to what @mturmon said; you'll want to keep in mind that even GUI tools (i.e. consider your favorite database tool that supports SSH connection) that support SSH connection will pick up this configuration so you don't have to manually plug in all of the pieces for each session.

Just specify the alias host name as configured in ~/.ssh/config and the user, identify file, and anything else you put there will be used as set.

This never occurred to me...I don't use GUI tools for database management outside of a local development environment or diagram generation.
