AWS Site-to-Site VPN

Extend your on-premises networks to the cloud

AWS Site-to-Site VPN is a fully-managed service that creates a secure connection between your data center or branch office and your AWS resources using IP Security (IPSec) tunnels. When using Site-to-Site VPN, you can connect to both your Amazon Virtual Private Clouds (VPC) as well as AWS Transit Gateway, and two tunnels per connection are used for increased redundancy.

For globally distributed applications, the Accelerated Site-to-Site VPN option provides even greater performance by working with AWS Global Accelerator to intelligently route your traffic to the nearest AWS network endpoint with the best performance.

Highly available

AWS Site-to-Site VPN delivers high availability by using two tunnels across multiple Availability Zones within the AWS global network. You can stream primary traffic through the first tunnel and use the second tunnel for redundancy — if one tunnel goes down, traffic continues to flow.


With AWS Site-to-Site VPN, you can connect to an Amazon VPC or AWS Transit Gateway the same way you connect to your on-premises servers. AWS Site-to-Site VPN establishes secure and private sessions using IP Security (IPSec).

Accelerate Applications

The Accelerated Site-to-Site VPN option improves the performance of your VPN connection by working with AWS Global Accelerator. AWS Global Accelerator is used to intelligently route traffic to the nearest AWS network endpoint with the best performance.

Robust monitoring

AWS Site-to-Site VPN gives you visibility into local and remote network health, and monitors the reliability and performance of your VPN connections by integrating with Amazon CloudWatch.
