Massive egress bill

Hi,

We have a bunch of really big files on Azure in a file share. And we access the files through a software we use. Which does a download from the master file and regular saves to merge to the main file.

In doing so the bandwidth (egress) charge is a lot higher than we previously thought it would be. Is there any way to navigate this? I read somewhere that you can limit egress through private IPs?

Cheers

    @Anonymous Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
    Is data transfer between Azure services located in Azure Data Center or outside?

    Yes, you can limit egress charges by using private IPs. You can use Azure Private Link to access your Azure file share over a private IP address from within a virtual network. This eliminates data transfer charges between your virtual network and Azure storage, and also provides enhanced security by eliminating exposure of your data to the public internet.

    Additionally, you can also consider using Azure ExpressRoute to connect your on-premises network to Azure. ExpressRoute provides a private connection between your on-premises infrastructure and Azure, eliminating exposure of your data to the public internet and reducing data transfer charges.

    You can also consider using Azure Files premium tier, which provides a provisioning model that guarantees performance based on share size. For more information, see the Azure Files performance documentation.

    Understand Azure Files billing: https://learn.microsoft.com/en-us/azure/storage/files/understanding-billing

    Throughput rate (ingress + egress) (MiB/sec)100 + CEILING(0.04 * ProvisionedStorageGiB) + CEILING(0.06 * ProvisionedStorageGiB)

    I would also recommend to reach Billing and Subscription, this team would be the best to provide more insight and guidance on this scenario: https://azure.microsoft.com/en-us/support/options/ based on your region, requirement and data, it's a free support

    Is data transfer between Azure services located within the same region charged?
    No. For example, an Azure SQL database in the same region will not have any additional data transfer costs.

    Is data transfer between Azure services located in two regions charged?
