Sorry to see you're getting downvoted, but it's probably because that's just too long of a story to put in a comment. The parent you're replying to was being sarcastic: he meant to say, "well if we're going to pay other people to do our job, why stop at Heroku? why not pay squarespace even more money to do more work for us?" A reductio ad absurdum.

Ironically, he's right. But, as someone pointed out: Squarespace is probably not relevant in a conversation about Kubernetes, while Heroku is.

What Kubernetes is, is a long story. Suffice to say: if you don't know what it is, count your blessings. :)
