Databricks Apps pricing

[deng_dev]

Hi everyone!

I was investigating Databricks Apps as solution for my task and didn't fully understood pricing.

I have found this page and it indicates it will cost 75$ / DBU for Premium subscription plan when using AWS cloud. Is it full cost or will there be any additional costs from AWS side?

Thank you!

The $75 per DBU Premium subscription plan price for Databricks Apps on AWS shown on the Databricks Apps pricing page reflects the charge from Databricks itself. https://www.databricks.com/product/pricing/databricks-apps

However, this is not the full cost you will pay when running Databricks on AWS. 

You will incur additional charges from AWS for the underlying cloud infrastructure

Databricks  + AWS costs simulation example : 

Databricks Apps Premium plan at the listed price of $75 per DBU on AWS. You run a medium-sized app that consumes 0.5 DBUs per hour.

Databricks usage cost for 10 hours:
10 hours × 0.5 DBUs/hour × $75/DBU = $375

Additionally, you run this app on AWS infrastructure, using EC2 instances (at an example rate of $0.10 per hour):

AWS compute cost for 10 hours:
10 hours × $0.10/hour = $1.00

Total estimated cost for running the app for 10 hours:
$375 (Databricks license) + $1.00 (AWS infrastructure) = $376

Thank you for details!
It it known which EC2 instance is used for Medium Cluster Databricks apps? Not sure if it is possible to calculate AWS side costs to get accurate costs for both Databricks and AWS sides for Databricks apps

For Databricks Apps on AWS, the exact EC2 instance types used for clusters such as a Medium cluster are not publicly and explicitly documented

Common instance types used in medium workloads might be similar to m5 or r5 families in AWS (e.g., m5.xlarge or r5.xlarge), which offer 4 vCPUs per instance, and clusters would have multiple instances to meet the DBU usage

Simulation :

Cost Component	Units Used	Rate per Unit	Total Cost (USD)	Notes
Databricks DBU usage	0.5 DBU/hour × 10 hours = 5 DBUs	$75 / DBU	$375	Premium plan DBU charges for Databricks Apps on AWS
AWS EC2 compute hours	4 instances × 10 hours = 40 instance-hours	$0.12 / instance-hour*	$4.80	Example: using m5.xlarge (4 vCPUs) or r5.xlarge instances at approx. $0.10-$0.15/hour
AWS EBS storage	1 TB (1000 GB) × $0.10/GB-month (prorated for 10 hours)	$0.0033 / GB-hour	$2.40 (approx.)	Prorated for usage duration (typical EBS SSD pricing)
AWS networking	Estimated 100 GB data transfer	$0.09 / GB	$9	Approximate outbound transfer cost
Total Estimated Cost			$391.20	Combined Databricks DBU and AWS infrastructure costs
