Hello Samli,
Good Day!
Regarding your query, the question is focused on identifying the most cost-effective solution to improve connection redundancy. Let’s compare the mentioned answer vs your answer:
—Establish another 1 Gbps AWS Direct Connect connection with corresponding private Virtual Interfaces (VIFs)— involves setting up an additional 1 Gbps Direct Connect connection specifically for connecting to each of the 10 VPCs individually via private VIFs. It provides high performance and reliability, but comes with significant costs and complexity due to the need for multiple VIFs and BGP peering. It is generally more suitable for scenarios where high performance and network stability are critical and budget constraints are not as stringent.
—Establish VPN tunnels from your on-premises data center to each of the 10 VPCs— is generally the most budget-friendly approach. VPN connections typically have lower costs compared to Direct Connect (check out the pricing here versus Direct Connect). Plus, terminating VPN tunnels on the VGW is a simpler setup compared to
managing multiple Direct Connect virtual interfaces (VIFs) and BGP
peering sessions. Even though you’d have multiple VPN connections, the overall cost and setup complexity remain lower.So, for a balance between cost and complexity, —Establish VPN tunnels—is likely your best option. It keeps things simple and cost-effective while still addressing the need for redundancy.
I hope this helps. If you have more clarification, pls let us know.
