Introducing AWS Site-to-Site VPN Concentrator for multi-site connectivity

This article introduces AWS Site-to-Site VPN Concentrator, a new Transit Gateway attachment feature that simplifies multi-site connectivity for distributed enterprises.

• Multiple remote sites share single VPN attachment to Transit Gateway
• Supports 5 Gbps aggregate bandwidth per concentrator with high availability
• Ideal for organizations with 25+ remote sites requiring 50-100 Mbps each
• Reduces operational overhead and per-site VPN costs through consolidated connections
• Automatic provisioning of two concentrator endpoints across availability zones
• Setup via AWS Management Console with three steps: create concentrator, create VPN connection, configure routing
• Supports IPv4, IPv6, BGP routing, and accelerated VPN connections
• Does not support static routing, ECMP, or Private IP VPN connections
• Integrates with CloudWatch metrics, VPN logs, and Transit Gateway flow logs

VPN Concentrator enables cost-effective, scalable multi-site connectivity for retail chains, restaurants, hotels, and healthcare providers managing distributed locations.
