Cloud prices only tell half the story. Know what you're paying for.
Compare the hardware, architecture, and performance behind the price. CloudCostDB puts the technical details alongside the numbers, so you can see what you're paying for, understand the trade-offs, and compare your options on more than cost alone.

View all- The Bedrock tier ladder: batch and flex at 50% off, priority at +75%
Bedrock charges $0.40 per million input tokens for batch or flex on Nova Pro and $1.40 for priority, against $0.80 standard. On a 10M-input, 2M-output month that is $7.20 to $25.20 for identical model weights. Tier coverage, prompt-cache breakeven, and the models where none of it is available.
- The 13% flexibility premium: Compute Savings Plans vs EC2 Instance Savings Plans
Across 1,360 us-east-1 Linux instance types, the median EC2 Instance Savings Plan rate is 86.9% of the Compute rate at one year and 86.8% at three years. The 13% gap is what AWS charges for the right to change family and region. It is not uniform: c7g carries 8-9%, m7i 10-11%, r7i 9-13%, and a 3-year p5 plan carries a 41% premium.
- Aurora's 21% compute premium is a backup discount
Aurora MySQL charges $0.580/hr for a db.r6i.xlarge against $0.480 on RDS MySQL, 21% more for the same vCPU and memory. Charged backups run $0.021 per GB-month against $0.095, a 4.5x gap, and Aurora storage is 13% cheaper. The breakeven sits at 779 GB of charged backup for a 1 TB database, or 409 GB of live storage per vCPU once backups reach 40% of your data.
