AWS VPC Peering Costs: Key Updates & Free AZ Data Transfer!
Are you curious about how to optimize your Amazon VPC costs? Understanding the nuances of VPC peering and data transfer charges can significantly impact your budget and overall cloud strategy, especially with recent changes in data transfer pricing.
Amazon Virtual Private Cloud (VPC) is a cornerstone of AWS infrastructure, offering a logically isolated virtual network where you can launch AWS resources. Understanding its pricing model is crucial for efficient cloud management. The pricing structure for VPC peering, a mechanism for connecting VPCs, has evolved, offering opportunities for cost savings.
Let's delve into the specifics. Since May 1st, 2021, a significant change occurred: all data transfer over a VPC peering connection that remains within the same Availability Zone (AZ) is now free of charge. This applies even if the VPC peering connects different AWS accounts. However, it's essential to be aware that charges still apply for data transfer across Availability Zones and Regions.
To gain a deeper understanding, let's look into the intricacies of VPC peering and how it impacts your AWS spending. This is where strategic planning is essential. Two popular options for interconnecting Amazon Virtual Private Clouds (VPCs) are VPC Transit Gateway and VPC Peering. While both provide a mechanism for enabling communication between VPCs, they differ significantly in cost structure, scalability, and use cases.
My customer is planning to create vpc peering with different aws accounts and they are confused who is the payer for data transfer in this situation. All accounts are in same aws region (seoul) account a (vpc a) vpc peering account b (vpc b) [scenario] vpc peering data in\/out = 0.01 usd\/gb
VPC peering is typically used to interconnect a small number of VPCs within a single region to establish full mesh connectivity. For larger-scale environments where numerous VPCs need to be interconnected, AWS Transit Gateway and AWS PrivateLink are the recommended mechanisms.
The cost of data transfer across different Availability Zones and Regions is a key factor. Its therefore crucial to architect your VPC peering connections strategically, considering data flow patterns and regional boundaries. This is particularly true if you are dealing with several AWS accounts. You can find detailed information about data transfer rates in the Amazon EC2 pricing section.
To answer the question of data transfer payer: In the scenario described (Seoul region, Account A peering with Account B), with data transfer within the same Availability Zone, the data transfer is free, as of May 1st, 2021. However, if the transfer crosses Availability Zones within the Seoul region, the standard data transfer charges would apply.
When a VPC peering connection is deleted, its visibility differs depending on whether it was created within the same AWS account or across different accounts. The peering connection remains visible to the party that deleted it for 2 hours, and visible to the other party for 2 days. If the connection was within the same account, the deleted request is visible for 2 hours.
The core of VPC peering is the ability to establish secure and direct communication between different VPCs. AWS provides the function that facilitates the smooth exchange of resources and data across various VPCs within the AWS cloud, organizations can leverage VPC peering to create private connections that enable them to do so.

The AWS pricing model for VPC is designed for flexibility and scalability, but it also requires careful attention to optimize costs effectively. Effective cost optimization strategies are essential to managing your Amazon VPC usage and maintaining budget efficiency. This involves understanding the pricing for various components, including data transfer, and choosing the right architectural design.
Let's break down the key elements for efficient VPC cost management:
- Data Transfer Costs:
- Within AZ: As mentioned, data transfer within an Availability Zone is free.
- Across AZs: Charges apply, and the cost varies depending on the region.
- Across Regions: Significantly higher costs are involved.
- VPC Peering Creation: Creating a peering connection itself is free.
- Other Services: Remember that other AWS services used within your VPC, such as EC2 instances, load balancers, and databases, have their own pricing models that contribute to your overall costs.
Effective cost optimization involves several strategies. It includes designing your architecture to minimize cross-AZ and cross-region data transfer, regularly monitoring your data transfer costs, and leveraging cost management tools provided by AWS and third-party vendors. Consider using services like AWS Transit Gateway for more complex networking requirements.

Vpc peering and transit gateway are used to connect multiple vpcs.
One critical area to explore is the usage of VPC Transit Gateway. For scenarios involving connecting many VPCs or establishing more complex network topologies, Transit Gateway can be an excellent alternative to VPC peering. It simplifies network management and provides centralized control, although it comes with its own pricing structure. The choice between VPC peering and Transit Gateway depends on your specific needs, scale, and architectural requirements.

For those planning for complex cloud networking, AWS Transit Gateway offers a more scalable solution compared to VPC peering, especially when dealing with numerous VPCs.
Virtual private cloud peering is known as vpc peering. It is an aws networking function that provides safe and direct communication between different vpcs. By using the vpc peering feature organizations can establish private connections that facilitate the secure and smooth transfer of resources and.
Let's summarize some key takeaways:
- Data Transfer Pricing: Remember that data transfer within an AZ is free from May 1st, 2021. Cross-AZ and cross-region transfers incur charges.
- Peering Creation: No charge to create peering connections.
- Cost Optimization: Careful planning is required to optimize data transfer and overall VPC costs.
- Alternatives: Consider VPC Transit Gateway for complex network topologies.
