AWS VPN enables secure connections between on-premises networks and AWS Virtual Private Clouds (VPCs) using IPsec VPN tunnels. Each connection includes two tunnels for high availability, terminating in different availability zones to ensure resilience. It supports both static and dynamic routing with BGP, and offers customizable tunnel options, including inside tunnel IP addresses, pre-shared keys, and BGP Autonomous System Numbers (ASNs). Accelerated Site-to-Site VPN leverages AWS Global Accelerator to route traffic through the nearest AWS edge location, improving performance by reducing latency and jitter. AWS Client VPN is a fully managed, elastic VPN service that allows users to securely access AWS and on-premises resources from any location using an OpenVPN-based client. It supports authentication through Active Directory, mutual certificate authentication, and SAML-based federated authentication.

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.
