Selecting the Right AWS VPN Solution: A Decision Framework

This article provides a decision framework for selecting the optimal AWS VPN solution based on site count, bandwidth, architecture complexity, and cost.

• Five VPN options now available: Standard VGW, Standard TGW/Cloud WAN, Large Bandwidth Tunnel, VPN Concentrator, Client VPN
• Standard VPN supports up to 1.25 Gbps per tunnel; Large Bandwidth Tunnel supports up to 5 Gbps per tunnel
• VPN Concentrator provides shared 5 Gbps aggregate bandwidth for multiple sites with up to 60% cost savings
• VGW suitable for single VPC with few sites; TGW/Cloud WAN for multi-VPC/account architectures
• Accelerated VPN reduces latency using Global Accelerator for latency-sensitive applications
• Client VPN supports up to 7,000 concurrent remote user connections with SAML authentication
• Five real-world scenarios demonstrate framework application: startups, global enterprises, manufacturing, retail chains, hybrid workforce
• Consider AWS Direct Connect for dedicated bandwidth exceeding 10 Gbps or sub-10ms latency requirements

The framework helps organizations avoid over-provisioning costs and performance bottlenecks by matching VPN solutions to specific hybrid connectivity requirements.
