AWS to bare metal two years later: Answering your questions about leaving AWS

Unfortunately it's not, and it gets more difficult the more cloud-y your app gets.

You can pay for EC2+EBS+network costs, or you can have a fancy cloud native solution where you pay for Lambda, ALBs, CloudWatch, Metrics, Secret Manager, (things you assume they would just give you, like if you eat at a restaurant, you probably won't expect to pay for the parking, toilet, or paying rent for the table and seats).

So cloud billing is its own science and art - and in most orgs devs don't even know how much the stuff they're building costs, until finance people start complaining about the monthly bills.

We run regular FinOps meetings within departments, so everyone’s aware. I think everyone should. But it’s a lot of overhead of course. So a dev is concerned not only with DevOps anymore but with DevSecFinOps. Not everyone can cope with so many aspects at once. There’s a lot of complexity creep in that.

Yeah, AWS has the billing panel, that's where I usually discover that after I make a rough estimate on how much the thing I'm building should cost by studying the relevant tables, I end up with stuff costing twice as much, because on top of the expected items there's always a ton of miscellaneous stuff I never thought about.

I have Claude, ChatGPT, and Gemini analyze our AWS bills and usage metrics once a month and they are surprisingly good at finding savings.

I have a fair idea of how much our cloud costs. However, others in the org don't want me to actually see how much it costs. Which is bonkers. I can help identify how we could rearchitect or investigate lowering our costs, if I know what they are and where to look first. No point guessing and accidentally optimizing something that will be an order of magnitude or more less beneficial.
