I would argue that the single command to begin using the application and the ease of on boarding / querying data was a huge factor in expanding its usage. Elastic optimized for initial spin-up and getting things running fast. It works really well! Until you load it full of data on a public IP, that is.

That single command to spin up the application can easily generate and show a copyable random secret required to use it, so that you can use easily but there's no option to use it that insecurely.
