Policy-as-Code VPC Private Subnet Proxy Deployment
The deployment pipeline was silent, waiting for the next commit to trigger the build. One change would set in motion a fully automated Policy-as-Code VPC private subnet proxy deployment, locked down from the first line of configuration.
Policy-as-Code brings infrastructure governance into code, ensuring every VPC, subnet, and proxy follows a defined set of rules before deployment. A private subnet inside your VPC isolates resources from public access, reducing attack surface. The proxy acts as a controlled gateway, enforcing compliance and security policies in real time.
With Policy-as-Code, these rules are embedded directly in your infrastructure-as-code templates. Terraform, AWS CloudFormation, or Pulumi can enforce them on every run. No human overrides. Every route table, security group, and network ACL is set according to the same baseline.
The deployment sequence is clean and repeatable:
- Define VPC with private subnets in code.
- Integrate proxy service into the subnet.
- Apply Policy-as-Code modules to validate configuration.
- Trigger pipeline to deploy only if all checks pass.
Using AWS, this means defining aws_vpc and aws_subnet resources with map_public_ip_on_launch disabled, connecting them to NAT gateways or VPC endpoints, then inserting the proxy—HAProxy, Envoy, or an AWS-native solution—behind strict IAM and security group rules. Policies verify CIDR blocks, route targets, and proxy health before rollout.
The advantage is not just compliance. It is speed without risk. Policies catch misconfigurations during planning. Private subnet proxies stay in sync with security requirements. Environments remain auditable and resilient under continuous delivery.
This approach scales. New services inherit the same governed network layout. No drift. No exceptions. The pipeline itself becomes the enforcement tool.
