Hi, i know that one can directly use data stored in an AWS S3-Bucket in an Azure Databricks Notebook. What i wonder is: will there be any additional (apart from the "normal" Databricks cluster costs) costs generated by doing so? I´m thinking about data egress from AWS and/or transfer bandwith etc. If yes, how could we estimate the amount of data that would be billed? Would only data that is physically "saved" to e.g. an Azure Storage Account after processing it in Databricks be taken in to account, or everything that is originally read into Databricks or.... Thank you!

Hello @M_H , There will be no additional charge from Azure Databricks End. If you are saving the data into Azure Storage Account, then you will be billed for the amount of data stored. You need to pay data transfer out from Amazon S3 to internet. From Amazon S3 pricing page, here is the data transfer cost. Hope this helps.

Hi @PRADEEPCHEEKATLA-MSFT ,
sorry for late respone - unfortunately didn`t receive the notification that there was an answer.

Thank you for the answer - does it mean if i create a dataframe from a S3 bucket containing e.g. 5GB of parquet files

this 5GB will be transferred to Azure environment (in some kind of temp storage)

i wil be billed for this 5GB (every time i read the files again)

?

Thank you!

Hello @MH-3502,
You pay for requests made against your S3 buckets and objects. S3 request costs are based on the request type, and are charged on the quantity of requests. There will be no additional charges from Azure. If you are storing the data into Azure Storage Account, then you will be billed for the amount of data stored.

Hi,

When using Azure Databricks with Azure Storage account, I see that you said that there will be storage costs ("If you are saving the data into Azure Storage Account, then you will be billed for the amount of data stored."), but I was wondering if there any egress costs for that? Would hosting Azure Databricks in a different region than the Storage Account, cause an egress cost?

Hello @Raj Rao ,

Every Azure Databricks workspace associated with the managed resource group. This Azure-managed group of resources allows Azure to provide Databricks as a managed service. Initially this managed resource group will contain only a few workspace resources (a virtual network, a security group and a storage account).

If you are utilize the default storage account for storage data it will be charged for the amount of data storage along with ingress/egress charges for accessing data.

Note: Azure Databricks workspace and the managed resource group will be in same regions.

Hope this helps.
