Cost of Bandwidth with respect to VNET Peering and Availability Zones.

Umar Farook 0

What is the cost of bandwidth for traffic between different VNETs in East US? My resources are in the same Availability Zone (Zone 1) in both VNETs. Will the cost be zero since they are in the same Availability Zone, or will VNET peering charges apply regardless of the Availability Zone?

Whilst data transfer (bandwidth) within the same zone is not charged, there is still a flat cost for VNET peering.
VNET peering in the same region would apply here https://azure.microsoft.com/en-gb/pricing/details/virtual-network/

Hello Umar Farook,

Thanks for your question.

Inbound data transfer is not charged by Azure. However, outbound data transfer incurs a cost, which is typically charged on a per GB basis.

Data transfer within the same availability zone is free. Since data transfer within the Availability Zone is free, VNET peering charges will be as here: https://azure.microsoft.com/en-gb/pricing/details/virtual-network/

Bandwith cost is cited from here: https://azure.microsoft.com/en-us/pricing/details/bandwidth/

Please take a look to have clear details

Also remember to use https://azure.microsoft.com/en-us/pricing/calculator/ for your Total cost

@akinbade abiola @Ben Gimblett Thank you for your response.

I want to understand the Data Transfer within the same AZ is free within a VNET or across VNETs as well?

My use case involves an AKS Nodepool in AZ Zone 1 in East US that sends logs to Elasticsearch VMs, which are also in AZ Zone 1 but located in a different VNET in East US itself. Both VNETs are peered.

Please explain the bandwidth charges that will apply when the resources are in the same Availability Zone versus when they are in different Availability Zones

Umar Farook ,

Wrt, "I want to understand the Data Transfer within the same AZ is free within a VNET or across VNETs as well?"

As long as the source and destination is in same Availability Zone, Data transfer within is free in both the cases

For Data Transfer charges in different Availability Zones within same region, see Intra-continental Data Transfer

Kindly let us know if this helps or you need further assistance on this issue.

Thanks,

Kapil
