VPN concept

Hi, forks 👋

I open this discussion to share the current VPN concept, and it will continue to improve.

Introduction to AWS-to-site VPN

First, I chose AWS, which has the highest market share. The concept of AWS-to-site VPN refers to creating a site-to-site VPN between AWS and another CSP.

Note: The site refers to VPC, VPC network, and Virtual Network. We refer to this as a "vNet" in CB-Tumblebug.

AWS-to-site VPN currently supports MS Azure, GCP, Alibaba, Tencent, IBM. Depending on the characteristics of CSP, dynamic routing and static routing are supported.

Terrarium can help you configure a site-to-site VPN, like ordering a combo at a fast food restaurant. We’ll handle what’s under the hood to ensure maturity and stability.

Actually, configuring a VPN is very complicated... 😟

This is because each CSP has different concepts/characteristics for VPN, and VPNs must be configured between CSPs.

The following figure is an example illustrating this, showing the various resources, information, and dependencies required to configure a VPN between AWS and Azure. In particular, dependencies affecting different CSPs make VPN control mechanisms more complex.

But don’t worry, Terrarium can handle this challenge. 😎
