Companies and network administrators in need of a solution to connect on-premises networks to AWS cloud resources
About AWS Site-to-Site VPN
AWS Site-to-Site VPN is a fully managed service that establishes secure connections between your on-premises networks and AWS resources using IPsec tunnels. Each VPN connection includes two tunnels, each terminating in a different availability zone, to provide increased availability to your VPC. If there's a device failure within AWS, your VPN connection automatically fails over to the second tunnel so that your access isn't interrupted. 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. AWS Site-to-Site VPN supports both static and dynamic routing options, including BGP peering, to give you flexibility in your routing configuration. It also supports NAT traversal, allowing you to use private IP addresses on private networks behind routers with a single public IP address.
