Cloud bills grow quietly. Startups often over-provision 'just in case' and pay for idle capacity every month.
Begin with visibility: tag resources, enable Cost Explorer, and assign owners for each environment.
Rightsize compute. Many services run fine on smaller instance classes or with autoscaling that actually scales down.
Use managed services carefully — they save engineering time, but watch request pricing and storage growth.
Prefer infrastructure as code so environments can be destroyed when unused (especially staging and demos).
