What is the primary architectural difference between HA VPN and Classic VPN in Google Cloud?

HA VPN is a software-based gateway that runs on a VM, while Classic VPN is a managed service with built-in redundancy.

HA VPN uses a single external IP address but relies on Cloud Router for failover, while Classic VPN uses two IP addresses for active-passive redundancy.

HA VPN uses two external IP addresses per gateway to provide redundant tunnels, while Classic VPN uses a single external IP address.

HA VPN uses a single tunnel with automatic failover to a second tunnel on the same IP address, while Classic VPN requires manual failover.
