What the Organization Policy Constraints Are

The Organization Policy Service provides centralized, programmatic guardrails that govern resource configurations across an entire Google Cloud resource hierarchy. Applying managed constraints at the organization node ensures that preventative security baselines automatically cascade down to all child folders, projects, and resources via inheritance, even restricting users with privileged project-level IAM roles.

How It Meets the Requirements

• Preventing external IP addresses on VMs: Enforcing compute.vmExternalIpAccess with a list policy configured to deny all external IP values (or an empty allowlist) blocks Compute Engine instances from being assigned public IPv4 addresses upon creation or network interface update.
• Disabling default VPC creation: Enforcing the boolean constraint compute.skipDefaultNetworkCreation ensures that when the Compute Engine API is activated in newly created projects, Google Cloud skips the generation of the default VPC network and its default firewall rules.
• Restricting Cloud SQL public IPs: Enforcing the boolean constraint sql.restrictPublicIp blocks the assignment of public IP addresses on Cloud SQL database instances, requiring workloads to leverage private IP networking or authorized proxy configurations.

Key Advantages and Capabilities

• Hierarchical Governance: Policies applied at the organization root automatically cover all descendants while allowing controlled granular overrides at folder or project levels when exceptions are justified.
• Preventative Guardrails: Blocks non-compliant resource creation at API invocation time rather than relying on reactive detection and remediation.
• Separation of Concerns: Decouples organization-wide compliance enforcement from project-level developer administration.
• Immutable Baselines: Ensures standard networking security baselines without requiring custom continuous integration policy scripts for every project.

Why This Is Optimal

Leveraging Google-managed organization policy constraints (compute.vmExternalIpAccess, compute.skipDefaultNetworkCreation, and sql.restrictPublicIp) is the native, platform-recommended mechanism to establish strict infrastructure configuration guardrails across the organization resource hierarchy.
