Finance teams chase cloud bills after the fact. The real levers were pulled months earlier, in architecture.

The expensive defaults

Over-provisioned instances, chatty services, and data moving across regions quietly compound. A right-sized, event-driven design often costs a fraction of a naive lift-and-shift.

Design for spend and speed

Autoscaling, caching, and storage tiering aren't just performance tools — they're cost tools. The same decisions that make a system fast usually make it cheaper.

Treat cost as a first-class engineering constraint and the savings follow the design.
