A site-to-site VPN allows offices in multiple fixed locations to establish secure connections with each other over a public network such as the internet. This extranet VPN allows the companies to work together in a secure, shared network environment while preventing access to their separate intranets. AWS VPN is made up of two services: AWS Site-to-Site VPN and AWS Client VPN. Each service offers a highly available, managed, and expandable cloud VPN solution to safeguard your network traffic.
