For a long time I was adding aliases to .ssh/config manually and managing things that way but a coworker introduced me to a couple of tools which made things much easier!
One is a tool similar to Shuttle to access all our EC2 instances called Elastics[1] (Mac). It provides a menu listing every EC2 instance, showing it's status, IPs, config details, cpu usage, etc and allows you to click to open SSH. It's not perfect but very handy!
I also use an in-house tool which queries the EC2 API to sync my .ssh/config with aliases for every server based on EC2 tags. If you're interested it's built with node.js using awssum [2] to query AWS and sshconf-upsert [3] to update the config.
