Architecting for Cost

Finance can't fix your cloud bill.

Your architecture caused it, and only architecture decisions can change it.

A self-paced video course for software architects and engineering leaders.

The savings dried up. The bill didn't.

Your company did the sensible things. It tagged everything, shrank the oversized servers, turned off what nobody used, and bought reserved capacity.

The first pass found real money. The second found a little. By the third, it took weeks of engineering time to find a rounding error.

And the bill is climbing again...

That's the floor. Finance can run the playbook perfectly and still get stuck there. Everything below the floor was set by design decisions. How many services you run. Where your data lives and how often it moves. How fast you need to recover when something breaks.

Each of those choices came with a monthly invoice. Nobody saw it when the choice was made.

Who this course is for

Architects and senior engineers who've been handed a cost target. You can name your five biggest line items. You can't yet say which design decision caused any of them.

Engineering leaders and CTOs who ran the finance playbook, hit its floor, and watched the bill keep climbing. You need your architects to own the next round, and a way to show finance it's working.

Not for: anyone looking for a console tour or a list of cost-cutting tips. This course is about the decisions, not the dashboards.

What you'll learn

  1. Your Bill Is a Design Document

    Why the finance playbook stops working, and how to read a cloud bill backwards, from each line item to the decision behind it.

  2. Cost as a Design Constraint

    Treat cost like availability and latency. Pick the unit that matters, and write cost into your architecture decisions.

  3. The Decisions That Dominate the Bill

    Where the money is. Service granularity, synchronous calls, and capacity sized for a peak you rarely hit.

  4. Multi-Tenancy and the Shape of Isolation

    The decision with the widest cost spread, and the hardest one to reverse. Including the customer who costs more than they pay.

  5. Data Gravity, Egress, and the Price of Boundaries

    Every boundary your data crosses has a toll. Plus what your recovery targets cost, priced rung by rung.

  6. AI Inference Economics

    Why inference breaks your cost model, and the routing, caching and hosting choices that set the number.

  7. Making Cost Visible and Enforceable

    Attribution that survives a re-org, showback that changes behavior, and cost checks that catch a decision before it ships.

  8. Making the Architectural Cost Case

    Turn a design trade-off into a finance argument, write the proposal that gets funded, and defend a number you don't control.
