Amazon SDE here. I'm not sure what internal infra you're talking about. Amazon's certainly isn't one of them.

And AWS, with its design by accretion, makes that an impossibility. Kubernetes by comparison is a paragon of clarity.

Why does AWS insist on building this way? Has anyone tried to get the teams together and say, "stop, let's evaluate and simplify where we can?"

As an AWS customer, I find AWS a huge pile of overcomplicated offerings that is dense with its own jargon and way of doing things. IAM is a trash fire. Everything built on IAM like IRSA is also a trash fire. Why are there managed worker nodes, spot managed worker nodes, Fargate worker nodes, self-managed worker nodes, and spot self-managed worker nodes? Why are there circular dependencies for every piece of infra I stand up making it almost impossible to delete any resources? Why can't I click on a service and see how much it costs me in one or two clicks?

This is a completely insane way of building software to me and I have to eat it.

Amazon has "Invent and Simplify" as one of the leadership principles. However, each team has its own hiring bar and culture, so some will take it seriously and some will not.

I fully agree. I'm speaking exclusively about the internal infrastructure, not about AWS.

As if they are trying to tie them to their proprietary platform to make migration to other cloud providers hard.

I can't even imagine, sometimes I feel like AWS offers this pretty facade of "scale it up easy" and in reality its like "wait, I can't even see why this thing is failing because its a layer below, and AWS support costs mega bucks"

You mean the infra behind non-AWS services like retail Amazon.com?

Or the infra underlying AWS itself?

The first one, but I'm trying not to divulge too many details on the architecture of Amazon - as you can imagine.

Fascinating because I would have thought the whole idea is AWS is dog-fooded by retail. Yet in truth AWS is itself too expensive and / or complex for Amazon itself! (Or at least the original part of it.)

The majority of retail is dog-fooding AWS, but a lot of code was written before AWS existed or before it provided many of the required services.
