An RDS database is growing and free space is falling below a threshold.
Prevent capacity exhaustion while reducing manual storage changes.
Which setting is most appropriate?
Enable RDS storage autoscaling and set a maximum storage threshold so storage grows as free space falls.
Detailed explanation
A CDN cache does not resolve a database storage-capacity shortage.

RDS can automatically increase storage as free space declines, within the configured maximum.

Foundation review
Capacity versus compute
Storage autoscaling changes disk capacity; changing the DB instance class addresses compute resources.
Bounded automation
A maximum size limits cost and capacity growth while avoiding a full disk.
