Massive egress bill

Question

Massive egress bill

James Ralph 46

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

Additional information: Limit Azure egress costs
Choose an Azure solution for data transfer
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?

Hi @Sumarigo-MSFT , cheers for the above!

We currently have a file share (UK South) with everyone connecting to it over SMB. No virtual network for the majority of users. We have 6 users using a VPN to connect instead from Poland. Also connecting over SMB.

I don't think we will have any data transfer within Azure because of this. It is purely from within Azure to the users externally over the public internet. Would you recommend the private links path? Would this not still have an egress charge when the software does a merge/download from the main file?

@James Ralph There are different types of networking charges. If you traverses the public network, they’ll be charged egress out of Azure which is documented here: Bandwidth pricing. If you are using a private endpoint, the private endpoint service has it’s own pricing which can be seen here: Private Link/Private endpoint pricing. If you are using a private endpoint with a VPN, they should still expect to be charged for network egress as described in the first link. If you are using private endpoints with an ExpressRoute, they typically wouldn’t have to pay for network egress, but they are having to pay for the ExpressRoute.

These are networking charges, not charges from Azure Files. We cannot control what the networking charges for these services, and these charges would apply if you are using alternative solutions such as a file server in an Azure VM or Azure NetApp Files, although they may appear differently (i.e. VMs and ANF don’t have private endpoints but do have other forms of networking that must be considered in the TCO analysis). If you are finds egress to be expensive, they should open a support case with the appropriate networking team to point out that egress is expensive. (I would recommend you to contact support, so If you have a support plan, I request you file a support ticket, else please do let us know, we will try and help you )

Please let us know if you have any further queries. I’m happy to assist you further.
