Amazon EBS Pricing: Why Deleted EC2 Instances Never Stop the Volume Bill
EBS is billed across six dimensions — gp3 storage at $0.08/GB-month, separate IOPS and throughput line items, io2 Block Express, snapshots at $0.05/GB-month, fast snapshot restore at $0.75/DSU-hour. Deleting an EC2 instance never stops the volume bill, and the gp2→gp3 migration is one of the cleanest 20% wins in cloud cost.
