Google Cloud NAT
Google Cloud NAT (Network Address Translation) is a managed service that allows instances in a Virtual Private Cloud (VPC) network without external IP addresses to access the internet for outbound connections, while preventing unsolicited inbound traffic from the internet. It provides scalable and high-availability NAT capabilities without requiring manual configuration of NAT gateways on individual VMs. This service is essential for secure and controlled outbound internet access in cloud environments.
Developers should use Google Cloud NAT when deploying applications in private subnets that need to download updates, access external APIs, or send outbound traffic without exposing instances directly to the internet. It is particularly useful for compliance and security scenarios where instances must remain isolated from inbound connections while still requiring outbound internet access, such as in regulated industries or microservices architectures.
