Hello, Every night i copy my backup to azure storage account and need information regarding the cost. Which one is cheaper between copy over internet or over private endpoint?

Answer 1

@Handian Sudianto Firstly, Apologies for the delay response here!
You are correct that if you copy data from on-premises to a storage account over a VPN connection, there will be no ingress charges. This is because the data transfer is happening over a private network connection and not over the public internet.

Ingress charges are only applicable when data is transferred into a storage account over the public internet. If you are using a VPN connection to transfer data, you will not be charged for ingress.

However, keep in mind that there may be other charges associated with using a VPN connection, such as the cost of the VPN gateway and the data transfer charges for the VPN connection itself. Make sure to review the pricing details for VPN connections to understand the full cost of using this approach.

If you still have any question I would recommened to please contact Azure Billing and Subscription team would be the best to provide more insight and guidance on this scenario: https://azure.microsoft.com/en-us/support/options/ it's free, and it's the best choice for you.

Hello @Handian Sudianto Let me try to shed some light on the pricing aspect of both of these options to help evaluate the more cost-effective option.

Copying over the internet:

When you copy data over the internet, you'll incur data transfer costs. These costs depend on the amount of data transferred between your source and the Azure Storage Account. The data transfer pricing applies to both inbound and outbound traffic.

Using private endpoint:

Azure Private Link allows you to access services privately on the Azure platform. With a private endpoint, your data remains on the Microsoft network. The cost for a private endpoint is $0.01 per hour. Additionally, you'll pay for inbound data processed when reading from the Azure Storage Account through the private endpoint. The same pricing tiers apply as for outbound data processed.

In a nutshell, if you're transferring large amounts of data frequently, the private endpoint might be more cost-effective due to the fixed hourly charge. However, if your data transfer volume is relatively low, copying over the internet could be more economical.
