Evolution of AWS Site-to-Site VPN

In Part 1, we talked about the origins of the Site-to-Site VPN Service in AWS. As consumers began to scale in the early days, they faced tunnel sprawl, performance constraints, and the need for a simplified design. AWS responded with Transit Gateway. How did Transit Gateway simplify architecture leading to smoother operations, better network performance, and a scalable blueprint for the future network?

The necessity for protocols to keep communication secure has been around since the dawn of the internet. The first ever VPN was jointly developed by a vendor consortium (which included Microsoft) in 1996, and came in the form of Point-to-Point Tunneling Protocol. Although many are skeptical about the value of VPNs in 2022 and beyond, customer consumption of cloud provider VPN services have paved the way for additional features and exponential scale.
