Site to Site VPN

Introduction

Site-to-site VPN provides a secure tunnel between two networks. Unlike, say, VPN peering, where you have a connection between one AWS VPC and another AWS VPC, site-to-site VPN allows you to connect two networks that are not even in AWS. You could connect an on-premise network to the AWS network, or you could connect two different cloud providers together, like AWS and Azure.

Here is an example of a Site-to-Site VPN between AWS and Azure

Here is a YouTube video that shows how to set up a Site-to-Site VPN between AWS and Azure.

Conclusion

Site-to-Site VPN is a great way to connect two networks that are not on the same cloud provider. It is also a great way to connect on-premise networks to the cloud.
