Amazon blog post in which they describe moving off serverless and to a good old monolith with a thought through architecture:

"Moving our service to a monolith reduced our infrastructure cost by over 90%. It also increased our scaling capabilities."

Looks like without the flow of free money, some teams are coming back to their senses.

Scaling up the Prime Video audio/video monitoring service and reducing costs by 90%

The move from a distributed microservices architecture to a monolith application helped achieve higher scale, resilience, and reduce costs.

I'm currently fighting microservices in my current employer!

First thing I said was, "Performance is going to SUCK."

And they said, "But, ... MIRCOSERVICES!!!"

(... entirely missing the point, obviously.)

So they got it working, ...

Aaaaand, ...

Performance SUCKS.

Who WouldA Thunk?!?!?! 🙄

Like, seriously; I'm "a backend guy," and just *watching* their demo makes me cringe. This thing is *Hard To USE*.

Years ago, I got an interview at Google!!!

I flew out. I did the interviews.

For the whiteboard coding interview, the guy kept saying, "You have unlimited memory."

I looked at the requirements and wrote a "traditional" one-pass small constant memory implementation.

He kept reminding me, "You have unlimited memory available!!!"

Well, I'm an old guy.

But I *do know* that *the fastest way* to process data coming from rotating media (or internet steams) is sequential one-pass.

Multi-threading / multi-processing *IS NOT FREE*!!!

Virtual Memory *IS NOT FREE*!!!

Network communication *IS NOT FREE*!!!

So, regardless of whatever "super-impressive ultra-modern technologies" you may have, one-pass with limited working storage is *Freek'n FAST* with all existing hardware.

They did not hire me.

(But I know what kinds of CPUs they buy. And that tells me that they are actually constrained by processing speed, *regardless* of what they may wish to believe, and what they tell others.)
