Ask HN: Where can I see many examples of real companies' software architecture?

All the systems design resources I can find are aimed at L4/L5, where the focus is e.g. on how to implement a rate limiter on a single machine, or at best saying you can distribute it by putting the counters on a cache server.

I'm trying for L6 and can identify many of the issues with a L5 design (redundancy, sharding, global latency, hot spots, local batching), but it's hard not to miss the obvious, and to offer practical/realworld solutions, when my day job is embedded compilers and not large scale systems.

This is mostly a rant but I appreciate suggestions.

I think the building construction analogy might be similar to a home which has seen multiple remodels.

Now imagine a scenario where you have an absentee owner with a lot of money, a permanently staffed architect and a bunch of extremely able, slightly competitive contractors all on staff - each trying to prove their annual salary.

The original one story building would quickly become an ten story nightmare of a building.

The purpose of each episode is for anyone to walk away having a reasonable understanding of why and how a company built and deployed their app with XYZ technologies without needing to know anything up front. There's over 100 different companies / individuals who were on the show.

I tried to make it as efficient as possible to get these details. There's a lot more detail than a few bullet points but it doesn't get super lost in the woods with a million low level details that's specific to 1 company. It's basically an hour or 2 conversation for each episode where we cover everything from building to deploying their app, lessons learned, etc..
