Solution overview

The example CloudFormation template can be useful for demonstrating both:

Setting up the environment

The following steps are oriented toward establishing a Site-to-Site VPN connection with AWS Transit Gateway deployment topology. Minor adjustments to the set up process are required if you’d rather deploy a Site-to-Site VPN with AWS Virtual Private Gateway topology.

Conclusion

In this post, I showed how you can you use open source tools in conjunction with AWS services to learn about and experiment with AWS site-to-site VPC capabilities. Using these tools, you can better understand how your organization might use VPN technologies to connect your on-premises network to your AWS environment.
