google cloud nat

Cloud NAT is a software-defined solution that lets certain resources without external IP addresses create outbound connections to the internet. Cloud NAT provides outgoing connectivity for VM instances created using Compute Engine without external IP addresses, private GKE clusters, and Cloud Run instances, Cloud Functions, and App Engine standard environment instances via Serverless VPC access. Cloud NAT’s proxy is designed to overcome the problems encountered by typical proxies. Knowing this, how is it different from typical proxies?
