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.
