There is millions of hours of engineering work in all of the services on AWS.

If you intend to replace it with either self-built or open source tools, you're gonna need a good two dozen people on it full time. Plus 24/7/365 admins to keep it running.

Or you can just take the cost and export the work to Amazon, which is usually a lot easier and cheaper in the long run.

I feel like just build/rum on your own hardware is the "I could build it in a weekend". It takes so much effort and you end up with a worse platform over time.
