That's what I'm currently using! The downside with configuring via CLI is that anyone who needs to update the cluster has to download the tool, make sure they have the right AWS keypair installed, make sure their config is correct, etc. I guess I could just install kops on a server, but provisioning a server to provision the server that provisions servers is just too meta for me.

A saas that puts a UI on top of kops would be ideal, but that might not exist as a standalone service.
