AWS VPN Gateway
AWS VPN Gateway is a managed service that enables secure connectivity between an on-premises network and an Amazon Virtual Private Cloud (VPC) over the public internet using IPsec VPN tunnels. It acts as a virtual router that routes traffic between the VPC and the customer gateway, supporting both static and dynamic routing via Border Gateway Protocol (BGP). This service is fully managed by AWS, eliminating the need for hardware or software maintenance.
Developers should use AWS VPN Gateway when they need to establish a secure, encrypted connection between their on-premises infrastructure and AWS VPCs, such as for hybrid cloud deployments, data migration, or accessing AWS resources from corporate networks. It is ideal for scenarios requiring low to moderate bandwidth (up to 1.25 Gbps per tunnel) and is commonly used in conjunction with AWS Direct Connect for higher performance or redundancy. Learning this skill is essential for roles involving cloud networking, security, or hybrid architecture design.
