Starting today, Amazon RDS is billed in one-second increments for database instances and attached storage. Pricing is still listed on a per-hour basis, but bills are now calculated down to the second and show usage in decimal form. There is a 10 minute minimum charge when an instance is created, restored or started.
Per-second billing is applicable to instances that are newly launched or already running in all AWS Regions except AWS GovCloud (US). Please visit the Amazon RDS pricing page for more information.
