HN comment order

I’ve been saying for a couple of years whoever builds a tool to one click deploy an AWS alike to run on local bare metal has built the next billion dollar a year company. I know of a lot of big shops that are desperate to get out of the cloud due to 7-8 figure AWS bills but their software and engineering is too tightly wound into AWS tooling.

They still have linked their OpenCollective account, where they have raised $10K and still have a balance of $5K. [0] It's not a lot in the great scheme of things, but, have they been using a platform that's seemingly built for communities and open source to bootstrap their business? Because this is not a 'open core' situation. They just closed the repo and ran away. If they had that idea all along, I feel like it hasn't be very, let's…

I use this project, but calling it 'fully functional' is quite a leap.

Are these re-implementations? Or does Amazon offer the source code for these services? Not meant as a critical question, I don't understand the origins of this repository and really how it can be.
